I did a search and couldnt find it.Im looking to see if anyone can help me with the fuel system diagram on a 87 gn.Just want to make sure im also asking for the correct thing.A diagram where it shows the lines from the gas tank and goes to the fuel rail and regulator.Which is the feed and return.Thanks in advance

passenger side of fuel rail is feed , driverside at regulator bottom is return
not counting the engine feed and return line assemblies that are attached to the motor the body portion of the fuel system feed is 3 separate pieces of 3/8 steel , the return is two peices of 1/4 steel
from the tank sender the feed (3/8" steel line ) goes above the axle on passenger side in 3/8" steel , short rubber hose then back to 3/8 steel line over the frame to the driverside frame rail where the fuel filter is mounted , then along the driver frame rail through the a-frame to the engine side fuel feed line which goes to up the driverside of the timing cover then over to the passenger side of fuel rail
the return is at the bottom of the fuel regulator on driverside of fuel rail
down the front of engine the engine side return line joins to 1/4" steel line which runs over the frame, then under oil pan , then along the passenger frame rail over frame to over the axle , short rubber line to the steel line that goes to the tank sender
the tank sender has about a foot of rubber hose (3/8, 5/16, and 1/4) from the top of it to the three steel lines that run above the axle
three because theres also the vent thats part of the fuel system
a 5/16 steel vent line that follows the return line path from the tank to the driverside front of frame where the emission canister mounted on the driverside inner fenderwell
