72 AC truck with two inlets on tank sender - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Can someone confirm the line routing for me on the two inlet tank sending unit?

On the two inlet sender units, I believe the smaller one is for the return line from the fuel pump. I cannot find any information on this setup and I would like to know if this is the correct routing.

I have not been able to find a listing on the fuel pump for the trucks but I am sure the later cars have them. My 69 El Camino has the return line coming back off of the fuel filter and I have seen fuel pumps on the mid seventies Corvettes with the fuel pump that has the return line on it.

Any help would be appreciated.

Mike,

I had not thought about checking Autozone! The Autozone site says that my local store has one for $12.99 with limited life time warranty.

Thanks for the information.
