  Q: How to replace the Fuel Tank Filler Neck on Cadillac DeVille?

  A:

  One must start fuel filler neck replacement by draining fuel from the tank until it reaches the level of the hose. After that raise the vehicle until you can access the wheel house filler pipe opening cover properly. At the beginning of fuel filler pipe removal start by removing both the Fuel Tank filler pipe ground wire bolt and the fuel filler pipe clamp before the pipe can be taken out. The first step for installation involves placing the fuel filler pipe while following it with the fuel filler pipe clamp which needs to be tightened to 4.2 n.m (37 lb in). Set the Fuel Tank filler pipe ground wire attaching bolt at 9 n.m (80 lb in torque) then put on the wheel house filler pipe opening cover. After lowering the vehicle you should fill the tank with fuel before installing the Fuel Tank filler pipe cap. To check for leaks, turn the ignition on with engine off for two seconds before turning it off for ten seconds followed by another turning on with engine off for leak inspection. Attach the fuel injector sight shield after finishing the installation process.
