Hey guys,
Today I pulled in the garage and smelled a big whiff of gas from under the hood. Looked around and sure enough my fuel rail is leaking!

It is leaking from the tube that connects the sides of the fuel rail in the back. This is the small tube that runs left to right, around the #4 and #8 injector.

Is there an o-ring in there I can change or is it ready to be thrown in the trash? I am curious if anyone has run into this and what they did to fix it.

Thanks!

 

There are o-rings in there. You can get a kit from the dealer or a parts store that actually carries parts and not just oil and filters.

 

So your saying the dealer sells a kit that will allow me to essentially rebuild the fuel rail? It doesnt look like the rail comes apart very easy though.

Have you done it before?

 

The rail is held on, by I believe 4 bolts. Once you pull the rail off, you'll have the injectors off with it. Now would be the time to replace them if you wanted to. Otherwise, you'll want a fuel injector o ring kit, the 2 o rings for the cross pipes and possibly o rings for the 2 fuel lines you'll be disconnecting to get the rail out.

Why all those? You're pulling the rail out, and if any of those rings are in bad shape, dried up, cracked, whatever, you'll need to go get em anyway. You may not know till you put it all back together and find a fuel injector leaking cause the old seal isn't sealing anymore. I'd definately put some new injectors on though. Who wants to yank the rail off again when/if one goes bad when you already had it off? You can get the o rings from most auto parts stores or the dealer.

 

Not to steal the thread, but how do you remove the injectors once the 4 bolts from the fuel rail are removed. I'm trying to get them off before i junk my old block.

 

Well, once you have the rail out... Each injector has a c-clip. Turn it till its no longer blocking the removal of the injector. Might need to use needle nose pliers or some other small tool to turn them. Pop off the clips and put them on the new injectors, as long as you are using stock style injectors. Otherwise they won't fit on say, SVO injectors or the like. You don't really need em, but if you can still use them, it can't hurt to have the extra help keeping the seals sealed.

 

If you go to our sponsor at the top of the page (TPI Parts) they stock the fuel rail o-ring kit. I believe it was 11.00 dollars plus 3 or so shipping.

They are great, I just ordered a o-ring kit, 2 sensors and a thermostat, they charged me 4.00 s/h combined via priority mail and got my order out the very next morning.

 

When you get the four bolts out and the fuel supply & return lines disconnected, you just lift off the rails and the injectors pull out of the manifold with the rails.

If you've never had the injectors out you'll probably have to work at it a bit since the injector o-rings will be somewhat stuck inside the intake manifold bosses.

It usually helps to clean the little space around each injector where it goes into the manifold with some cleaner and compressed air first. Then maybe put on a drop or two of oil in that same space before trying to pull them out.

If you have not done this before, be sure to remove the two "hidden" bolts (one each side) holding the runners to the intake manifold before you start prying on stuff. No, I didn't wreck anything, but almost...
