I'm just getting around to hooking up my rebuilt sending unit and new Carter pump. It's out of the gas tank and ready to bench test. When I hooked power up to the sending unit, the fuel guage pegged to full even though the float is hanging down in the empty positon. When I cranked the engine over while the pump was submerged in a pail of gas with a hose going to another pail, nothing, no pumping of gas or anything. There has been no changes to the wiring/eletrical except a new coil last fall.

I no not much about wiring electrics but can follow directions pretty well, what should I be looking for. My volt meter says power is going to the wires for the sender/pump. Help please.

By the symptoms I would say you're missing a ground, but you say you've checked with a meter. It is possible you've blown the fuse, and the voltage you found with the meter is coming through the sender wire.
Wiring is pretty simple:
Blue- pump +
Tan- gauge sender
Black- ground

Thanks Spenser! The Beast lives!! First time around the block in a year or more! It was a disconnected ground wire. The new sender unit appears to be working and the fuel pump seems to be pumping.
Kicking it into gear now for next years Monzaque!

Rick, who rebuilt your sender, what cost and turn around time. Mike

I used Tristarradiators. Here's a link to an old post with before and after pics. Turn around time was less than two weeks if I remember correctly, and they were great to deal with.

Can't remember exact cost but i'm sure it was less than $100.
