Next week I will try to get the new fuel pump and sensor in the fue tank. I plan to bolt the fuel pump on the sensor, if that’s the correct location for it.

I might suggest the 87 V6 (EFI) sending unit & pump assembly. Holley says the stock pump may not provide enough volume & they have a replacement unit

thank you. Other fuel pump I’m installing is a Holley 19-369. How should it be fastened in the fuel tank.

I used the V6 unit, (replaced with the Holley pump) in tank, and it has quietly done well.

This is a brand new 19-369 pump. what’s the issue that won’t let it work in my fuel tank?

My fuel tank is a Spectra not a V6 tank. It doesn’t have a plastic cups in the bottom. How should I mount the Holley fuel pump in this tank?

What material does the electrical connector need to made of to stand up against the gas and seal the fuel tank so it won’t leak?

Sorry I don't have the answers you're looking for. I used the V6 drop in fuel sending unit/ fuel pump and it had the electrical connections.

Mine has electric connections for the fuel sender, I just need to make a hole for the fuel pump wires to come through to connect to the EFI system.

Can you locate a picture showing the top of sender where the wires come out of it? It might help me see where I need to put it in.

Will it work to remove one of the tubes out of the old sender and put it in the top of the new sender,to be used as a return line?
