Is there a gasket or o-ring that goes in between the fuel line and fuel rail connector. I've been to countless auto part stores and no one seems to know what goes in between. Any help would be greatly appreciated.

 

It runs at 60-70psi so there must be a gasket in there, but I couldn't find one listed either.

 

I figured what goes there. It's an o-ring. I used the same type of o-ring that the injector uses. Thanks for your reply.

 

it has an o ring that goes on it

 

I just finished replacing driver's valve cover gasket on a 2001 Ranger SOHC 4 liter V6 and had a leak when reconnecting fuel line to fuel rail. The O -ring
seal at the flange where they bolt together had deteriated. The Ford dealer doesn't list it and I couldn't find it on line anywhere. I visited a n Autozone store and they didn't have a selection of high pressure gas resistant O- rings but the guy said it looked a lot like the fuel injector gaskets for the Ranger..He went back and brought out a card of 4 O-rings for the injectors. They looked indentical so I bought it. I went home and installed one..and voila! no leakes. Hopefully its the same O- ring for the 4 cyl and 3.0 V6. Its Fel-Pro ES 70599 part at Autozone. ( about $6)
