On my 89 Iroc where the front crossover fuel line meets the passenger side fuel rail, it is leaking after I changed out injectors. It is making a horrible whistling sound and I was wondering if there is an o-ring in there I could replace and if so would it require I remove the whole fuel rail with injectors again? When I took it out the first time when everything was loose and the fuel rail was kind of pressured up still I was moving it around and fuel was squirting out of that connection.

 

There are o-rings everywhere. In order to replace that o-ring, you will have to remove one of the rails though.

 

Yes there are o-rings in there that should have been replaced. You can get a o-ring repair kit from the dealership that will have all the o-rings for the fuel rail.

 

Thanks for the replies.
How many o-rings are there to replace on the rail itself and how hard is it to replace them. Do you just pull apart the crossover line from the fuel rail in the same manner that I pulled the injectors out of the rail?

 

See attached picture for reference.

 

man I have to get a hold of those GM exploded view diagrams, where did you get it?
