Welcome to the forum! :welcome5:

What year is your truck? If you take the time to fill out your signature, it will help members give you some better help.
 
Should be the one from FFM to IP. It go's under intake then up to IP. Assuming yours is 94-2000 truck?
 
3/8" feed to the FFM (rubber hose), 1/4" from FFM under intake to the IP (3/8" if one has upgraded to the Feed the Beast Mod FFM to IP).

truck is a 1997 k2500 ext cab. i bought a us engine production drop in. the first steel line runs btween fuel injectors on front of engine to return fuel from injectors to tank. i can see where that one goes. the other line has 90 degree bend on both end of steel line. approx 18 inches long.

on stell line that connects right and left cylinder fuel return lines there is a hose that goes to injector pump return fuel but also another fitting to ?????????? not sure.

i have pictures but cant figure out how to attach them to the thread. sorry my computer skills suck
 
Testing my memory (need to go look at my truck). Sounds like the return line that tee's into the right to left bank return line.
It go's under manifold to rear of engine and connect to return line behind FFM.

Does the line you refer to have clips for bolting it down?

thats it!!! it has two clips for mounting it. i assume it connects to the crossover line between the left and right bank.i have intake off and wanted to ensure it went on prior to me seeting the intake. is there any pictures showing this line and where it actually bolts to?

does it have to be mounted under the intake? or does it go on after the intake is mounted? i knew i didnt take enuf pictures
 
You can just drop on pass side of IP in the valley then install it after the intake is installed.
 
ok. i got another question..... the wiring harness that runs along left side of engine has three connector plugs two go to my air conditioning compressor and the third i marked as crank position snsor when i removed engine over a year ago. i installed a new crank position sensor before dropping in engine and now i am not sure about this third connector(i may have marked it incorrectly) because i had a corresponding connector from the crank position sensor to a connector under intake manifold near Injection pump.

Does anyone know where this third connector in bundle running along left cylinders actually connect?
 
I think, but dont quote me, that third connector might be the coolant temp sensor for the guage, located in the left. cyl. head.
