Hello everyone Im working on a 96 Jimmy and need help with routing the gas lines.I have the major line with fuel filter complete.Underneith there are 2 lines with rubber fittings near the back.1 is has a high pressure fitting and the other isnt.I suspect one of them goes to the out line to the engine but where does the 3rd line go?Help please.

 

3/8" line is fuel pressure to the injector housing. 5/16" line is fuel return from the fuel pressure regulator back to the tank. 1/4" line is fuel vapor to the vapor canister.

 

I`ll try and get a pic sometime today so I can show you guys what Im talking about.2 of the lines are the same size none of them are 1/4er inch.

 

Ok this isnt working help trying to upload photo
