Fuel rail and fuel line question

[Northup]

Was in the process of taking of the intake and exhaust manifold to get at a freeze plug and have run into a little snag. Mj is a 1991 4.0L There are 2 fuel lines that rune to the fuel rail. The lines don't want to come off the fuel rail. Is there a secret to get these lines off? They seem to be a push on connector but I can't seem to budge them.

Maybe this will help.

If your trying to replace the freeze plug on the side of the block,you can without pulling the intake/exhaust manifolds. I speak from experience. It aint easy but can be done. If your lucky and get access to a installer tool, some auto parts stores might have loaners. I had to use a socket and wobble extension. Took awhile, but worth not having to pull manifolds. Good luck.

Thanks Fiatslug that is exactly what the doctor ordered. Now the next question is anyone know how to realease the fuel pressure? I think I have a wrangler chilton around it should be similar.

There's a schrader valve on the fuel rail, remove the cap and press the stem.

ya i found that and removed the pressure. Fitting still does not want to come off. Going to work on it more in the AM
