1971 part identification Options

EDITED to put smaller pictures below.


Ok, so my sister has a 1971 Porsche 914 that somehow I've been asked to get running again. It's had a few too many people under the hood over the years so there's quite a list of projects to do.

So first question is there a good manual that would be recommended for these so I might not have to ask question like will be below. Haynes, Chilton, ??

One of the first project is new fuel line front to back as they are pretty rotted. Next project is to verify the wiring as there's been a lot of playing around with the double relay.

Since I'm doing fuel lines the tank is out. Under the tank was a vacuum type line that didn't seem to have a home. Any suggestions where this was supposed to go. Come through the floor loops around and ends up by steering shaft.



Next question is what are the correct names two sensors? They are part of the double relay wiring and I'm tracing wires. Blue one, Brown one.


And then for now on this thread. What is this?

Great thought on recording the part numbers. Since its all apart its a good time.

So maybe this will help the wiring mystery. The fuel pump is currently wired from a harness that runs along the wall in front of the engine, from the relay panel. When I was under the car I thought it might of been a previous attempt at making it run by bypassing the relay, but then I saw it went into what looked like a factory harness on top. I've not worked on tracing those yet, but it certainly wasn't hooked to the dual relay.

So was the 1971 FI fuel pump originally powered differently?

I'm guessing if I get the dual relay worked out and this seems to be newer FI that it would be best to power the fuel pump from the relay.
