4th one my IP - notice the green wire clip on the top, just right of center, that was broken! could be one of my problems - it was like that I didn't do it. Green wire -ground? NO!!! Not a ground!
In general we need a different kind of "focus/zoom" in the pictures. For example a close up picture with the wire in question on the IP would help us better. I really have no idea where this rotted out fuel line comes from or goes as it's on the tailgate. I suspect it may be a return line from the IP and injectors like they do in pickups. The Fuel Filter picture makes me second guess that. The line on the engine in a picture would help us "See" it. Pictures really help us help you.
The IP generally has three wires: Pink is ignition on run: is +12V with key on. Remove 12V engine stops. Next we have two green wires that are tied together for "Cold Advance" and high idle. One wire goes to the top of the IP (cold advance) and the other goes to the high idle solenoid. They come from a temp switch generally in the thermostat crossover. Is should have the two connectors on the switch reading "0" ohms when cold. It opens around 140F I recall. If the engine shuts off when warming up you got the green and pink reversed on top of the IP. Engine running pop the pink wire off and engine should stop.
Green is NOT a ground in automotive wiring. Black may be a ground, but, not always.
