I am looking to replace a leaking fuel injector rail for 1993 fifth ave chrysler new yorker p/n 4554109


The rail is most likely not the problem, the fuel injector "O" ring seals are likely the problem in the rail.

1993 dodge dinesty 3.4 fuel rail leaks how can i repair


If the metal fuel rail itself has a leak, it should be replaced. If it is leaking by an injector, the O-rings on the injectors need to be checked and probably replaced. If a fuel line to the rail is leaking, that will have to be repaired. There will be two fuel lines at the rail, the feed line in from the gas tank, and a return line from the rail back to the tank. If there is a pressure regulator on the fuel rail (it will have a short vacuum line hose to it), the regulator may also have an o-ring to keep from leaking where it mounts.

MY 1998 CHEVROLET CAVALIER WILL NOT START


sound like the o rings are worn out on fuel rail when you pull the rail out slightly you are pinching the bad O ring making a seal car is starting. I would replace all O rings check fuel injector seals too, any and all vacuum lines and the seal on the fuel regulator especially if it is connected to the fuel rail.
also check and see if you are moving a wire connections when moving the fuel rail possible loose connection.

My 1996 cavalier is leaking fuel from the fuel rail how do i fix it?


Well, it could be leaking through damaged o-rings on the fuel rail at the fuel injectors. Maybe get a new set at the local salvage yard and install it on the car. Clips hold the injectors onto the rail.

This is a very dangerous condition, and if not experienced with working around gasoline, maybe should try to get a technician to do it for you.

Most definitely, relieve the pressure before removing the fuel rail from the cylinder head and removing the injector from the rail along with the o-ring.

After removing the fuel injectors and rail to remove the manifold, how do you reinstall the fuel injectors?


the same way you took it apart. put a little grease around the rubber seals so they will slide in easier. just tap on the fuel rail while lightly tapping it into place.
