Just replace the line

thanks fasteddie383, i had already checked with the library (actually, i've checked three different LARGE libraries, no luck!) i've even had two different friend's that i went to school with check around @ the two GM dealership's where they work-one's the service manager, the other's the shop foreman-no luck! i thought about looking @ those sites that charge a fee for a year's worth of access, but they have no guarentee i can find what i'm looking for, and no refunds.
as for our "guest" on Jan.02........"i have a 86 2.5 liter , i dont know the vacuum routing and i with i knew where fuel pump prime wire terminates within the vehicle. "????? what the hell?......first you're talking about a 2.5 (4 cylinder) that's in (eithier) a S-series Blazer/Jimmy, or p/u............did you not see that it's for a Suburban with a 350. different truck and different engine equals different diagram, but thanks anyways.

SOURCE: How to install a fuel line on rear fuel rail (back of engine)

I did this job on my 3.1 about 2 months ago and i forgot to put the ("O") ring on back fuel rail. had a fuel mess!! had to tear down plenum to fix, in my case i lost the o ring on rail and forgot to put 1 on. I had to order 1 from chevy garage, and replaced it. cost 9.00 just for 1 little o ring. mine fit tight also!! see if o ring is ok, and check line. car runs fine!!

Use a industrial vacume tester, check each port coming off of the manifold, run your lines.
