Link to my photobucket. The first five or so pictures are the fuel pump and level sending unit. There are also pictures of the car for those who are interested.

Looking at pics 4 and 5 it's clear that is just the pickup, not a pump. Try to get things working by replacing the suction hose from the pickup/sending unit in picture 4, 12MM I think or 1/2" if you're in a pinch, then with everything installed, pull the air boot off and with the ignition on, push in on the AFM flap. You should hear a click from the combo relay and it should be pumping, that's how it's switched.

Early to mid are the same, late are an internal one and not the same or interchangeable. I think it will be obvious as to go/no go.

Just to follow up, I got the new pump and replaced all the rubber lines. It fired up almost immediatly, but it needs some work. I am building a new engine for it now. I also picked up some rial mesh wheels.

I have a build thread over on bf.c, am I allowed to link it?
