The first step to replace the fuel tank pressure sensor requires removal of the fuel sender assembly. Removing the fuel tank pressure sensor should be your next step when working on the fuel sender assembly. When installing the new fuel tank pressure sensor it should be placed on the fuel sender assembly followed by reinstallation of the whole assembly.

The first step to replace Fuel Tank Pressure Sensor (NT7, NU5) requires removal of the rear compartment liner. First remove the cover bolts from the fuel sender access hole before taking out its cover. Once you disconnect the fuel level sensor wiring harness electrical connector from the fuel tank pressure sensor the sensor with its seal assembly will become removable. The new fuel tank pressure sensor installation requires you to position both the sensor assembly along with its seal then connect the fuel level sensor wiring harness electrical connector to the device before securing the fuel sender access hole cover. Fasten the fuel sender access hole cover bolts with 2 Nm (18 lb in) torque. Finish the procedure by reinstalling the rear compartment liner.

A technician must use ch-48027 or do not use it to eliminate fuel system pressure before Fuel Pressure Sensor replacement on the fuel injection Fuel Rail. The first step involves extracting both the Intake Manifold and the foam insulator situated on the fuel rails. Clean the location where the sensor attaches to both the fuel line and fuel injection Fuel Rail yet ensure you avoid contaminating the area then exercise care when handling the plastic sensor housing. A 27 mm socket should be used to remove the Fuel Pressure Sensor from the fuel injection Fuel Rail after sensor discard. Absorb all remaining fuel from the Fuel Rail and sensor area before drying this area and the sealing cone inside the rail with a lint-free cloth to ensure complete absence of fuel and debris. Apply gm p/n 12345610 (Canadian P/N 993193) silicon-free engine oil or equivalent to both the sealing cone and threads of the new Fuel Pressure Sensor along with the Fuel Rail. Replace the new Fuel Pressure Sensor at the fuel injection Fuel Rail with hand tightening but remove it and relubricate according to earlier directions. Fasten the new Fuel Pressure Sensor onto the fuel injection Fuel Rail until torque reaches 33 nm (25 lb ft). The replacement process includes putting back the foam insulators into both the fuel rails and the Intake Manifold. Replacement of the Fuel Rail is necessary if the fuel leak occurs at this Fuel Rail component. To inspect for fuel leaks turn on the ignition with engine off for two seconds while checking for any fuel leaks followed by turning off ignition for ten seconds before checking for further leaks when re-turning on ignition with engine off.

The first step to replace the Fuel Tank Pressure Sensor requires uninstalling the rear compartment liner. Start by removing the cover bolts leading to the fuel sender access hole followed by removal of the cover itself. After disconnecting the fuel level sensor wiring harness electrical connector the pressure sensor can be removed from the fuel tank. It is essential to install the new sensor while using the NEW seal that comes with the replacement. Use the fuel level sensor wiring harness electrical connector to connect with the new fuel tank pressure sensor before putting the fuel sender access hole cover into position. Fasten the fuel sender access hole cover with bolts that should be tightened to 2 Nm (18 lb in) before putting back the rear compartment liner.

As a first step to replace the Fuel Pressure Sensor on a 3.6l engine one needs to relieve the fuel system pressure. Start by removing both the cross vehicle brace and Intake Manifold before taking off the foam insulator from the fuel rails. It is important to avoid touching the plastic sensor housing with direct force yet you can use its hexagon for the tightening or loosening process. A 27 mm socket will be used to remove the Fuel Pressure Sensor from the fuel injection Fuel Rail for disposal. Deplete all fuel from the Fuel Rail and sensor location before using a lint-free cloth to dry both the sealing cone inside the rail and its surrounding area. Check that the sealing cone remains free of fuel as well as debris while being burr-free. Apply gm p/n 12345610 (equivalent to Canadian P/N 993193) silicon-free engine oil to the threads and sealing cone in the Fuel Rail followed by new Fuel Pressure Sensor treatment with the same lubricant before installation. Screw the new Fuel Pressure Sensor into the fuel injection Fuel Rail but only achieve hand tight contact then remove it to apply lubrication once more. Finish the process by installing the sensor to the rail while tightening it to 33 nm (25 lb ft). Fasten the new Fuel Pressure Sensor onto the fuel injection Fuel Rail by torquing it to 33 nm (25 lb ft). The foam insulator should be installed before the Intake Manifold takes its place. The replacement of the Fuel Rail becomes necessary when a fuel leak develops from this area. The ignition should be turned on when the engine is off for two seconds before being turned off for ten seconds then turned on again with the engine off to check for fuel leaks. Everything will finish with reinstallation of the cross vehicle brace.

The procedure to change the fuel injection Fuel Rail Fuel Pressure Sensor starts by using an appropriate method to pat the high side fuel system pressure. The first step includes disconnecting the fuel injector wiring harness electrical connector from the fuel injection Fuel Rail Fuel Pressure Sensor but avoiding any movements of the foam insulator to prevent damage. Use a 27 mm socket inserted through the foam insulator access point to grasp the fuel injection Fuel Rail Fuel Pressure Sensor but apply pressure only on the hexagonal mount to protect the sensor. Install a shop towel under the sensor position before you pull out and dispose of the exhausted sensor to allow fuel to drain. Inspection of the Fuel Rail sealing cone requires drying it first before checking for any residue or dirt. Apply silicon-free engine oil gm p/n 12345610 (Canadian P/N 993193) equivalent to lubricate the threads and sealing cone of the Fuel Rail as well as the new fuel injection Fuel Rail Fuel Pressure Sensor. Before final tightening to 33 nm (25 lb ft), hand tighten the new sensor then remove it followed by a lubrication procedure of reinstallation. After installing the new high-pressure fuel line the technician should connect the fuel injector wiring harness electrical connector and place the new low side fuel pressure service port cap. Check for fuel leaks by first placing a paper towel between the sensor and generator then start the vehicle for five minutes before cessation to evaluate the towel for fluid presence. Repetition of this series of steps is needed when wetting is identified.

The first step to replace the Fuel Tank pressure sensor requires properly elevated and supported vehicle position to reach the Fuel Tank through the wheelhouse liner. A vehicle with crew cab configuration requires reducing the Fuel Tank position. Move on to remove the left rear pickup box wheelhouse liner. The pressure sensor needs removal from the Fuel Tank module by disconnecting its chassis wiring harness electrical connector and pulling it directly upwards. The sensor requires clean engine oil for light lubrication before installation where it should be fully pressed into the Fuel Tank module. Insert the pressure sensor into the Fuel Tank module before connecting its chassis wiring harness electrical connector and placing the left pickup box wheelhouse liner back in position. The Fuel Tank installation process should be performed prior to dropping a crew cab vehicle.

The first step to replace the fuel injection Fuel Rail Fuel Pressure Sensor requires removal of high side fuel system pressure. Cut the electrical connection of the fuel injector harness from the Fuel Pressure Sensor on the Fuel Rail. A 27 mm socket should enter through the foam insulator opening to connect with the fuel injection Fuel Rail Fuel Pressure Sensor but the plastic housing can't experience any manipulative force. Position a clean towel under the sensor area before taking out the fuel injection Fuel Rail Fuel Pressure Sensor which should be safely discarded to drain possible fuel from the region. Check the Fuel Rail sealing cone for cleanliness after drying it with a clean rag. Silicon-free engine gm p/n 12345610 (Canadian P/N 993193) or equivalent oil should be used for lubricating threads and sealing cone areas of the Fuel Rail as well as the new fuel injection Fuel Rail Fuel Pressure Sensor. Tighten the new sensor by hand first before unlatching it to re-lubricate. Finally tighten the sensor to 33 nm (25 lb ft). The fuel injector wiring harness electrical connector needs attachment while you install a new high-pressure fuel line and cover the low side fuel pressure service port. The technician must start the vehicle after installing the new fuel fill cap then idle it for 5 minutes before checking for leaks by observing a paper towel resting between the sensor and generator. Never skip testing again when wetting occurs. Perform the same previous procedures.

The replacement of Fuel Tank pressure sensor (NU6) requires completing the Fuel Tank replacement (NC7) procedure which eliminates the Fuel Tank. The technician should disconnect the wiring harness electrical connector which controls the Fuel Pressure Sensor. The operation of replacing the evaporative emission (EVAP) canister does not require its removal. A flat bladed tool should be used to gently extract the Fuel Pressure Sensor from its position in the evap canister. Before installing the Fuel Pressure Sensor into the evap canister apply a tiny drop of clean engine oil to its fuel pressure seal. To complete the installation connect the electrical Fuel Tank wiring harness onto the Fuel Pressure Sensor before putting back the Fuel Tank following the Fuel Tank replacement (NC7) procedure.

The first step for Fuel Tank Pressure Sensor replacement on the 2500 Series begins with cleaning all fuel and evaporative emission (EVAP) line connections along with their surroundings to avoid contamination before starting. The next step involves removing the intermediate fuel line together with the EVAP line. A straight upward force will help you safely detach the fuel pressure sensor. The new fuel pressure sensor requires lubrication of its sealing mechanism before being inserted into the line. The replacement procedure ends with reinstallation of both intermediate fuel and EVAP lines. Rephrase this step using the appropriate procedures for the listed Fuel Hose/Pipe Assembly Replacements.

The first step to replacing the Fuel Pressure Sensor involves removal of the front propeller shaft if the vehicle operates with 4 wheel drive (4WD). You must disconnect the chassis wiring harness electrical connector which serves the Fuel Pressure Sensor . A shop towel should be used to soak up fuel leakage while removing the Fuel Pressure Sensor from its fuel line position before discarding the Fuel Pressure Sensor o-ring seal. Start by applying clean engine oil to the new o-ring seal of the Fuel Pressure Sensor before installing it onto the fuel line fitting. Place the shop towel around the sensor fitting of the fuel pressure line to prevent fuel from leaking. Follow these steps to attach the Fuel Pressure Sensor onto the fuel line by tightening it to 15 nm (11 lb ft). Install the Fuel Pressure Sensor by connecting its chassis wiring harness electrical connector and then lower the vehicle. To detect leaks in the system turn the ignition switch on with the engine power off for 2 seconds after which you must turn the ignition switch off for 10 seconds followed again by turning the ignition switch on with the engine power off while checking for fuel leakage. Front propeller shaft installation should be performed only if the vehicle contains 4wd functionality.

Vehicle owners must detach the front propeller shaft when replacing the Fuel Pressure Sensor only on vehicles with 4 wheel drive (4WD). First disconnect the chassis wiring harness electrical connector from the Fuel Pressure Sensor. Then use a shop towel to cover the Fuel Pressure Sensor fitting which will absorb any leaking fuel. To replace the Fuel Pressure Sensor you should first remove it from the fuel line and discard its o-ring seal. Clean engine oil must be applied to the new o-ring before you install it on the fuel line fitting. Place another shop towel on the fitting of the Fuel Pressure Sensor to prevent fuel leakage before fitting the sensor to the line. Fasten the Fuel Pressure Sensor to its fitting on the fuel line by torques to 15 nm (11 lb ft). The chassis wiring harness electrical connector needs installation onto the Fuel Pressure Sensor before lowering the vehicle. Check for fuel leaks by first keeping the ignition on while the engine stays off for two seconds and then making the ignition off for ten seconds followed by another two-second ignition on period with the engine still off. During this sequence inspect for any fuel leakage. After installing the front propeller shaft you must reinstall it only when the vehicle includes 4wd.

A proper replacement of the Fuel Pressure Sensor begins with elevating and supporting the vehicle. The Fuel Pressure Sensor requires removal of the chassis wiring harness electrical connector. A shop towel should be wrapped around the Fuel Pressure Sensor fitting to catch leaking fuel but remove the sensor from the fuel line after which discard the o-ring seal. Apply clean engine oil to the new Fuel Pressure Sensor o-ring before placing it onto its corresponding fuel line fitting.
