I used a
GM Fuel pump It worked out great for my 51. Im running GM fuel injection so it only seemed right.
It was around $350 for everything ( The pump cost $80.00 at the dealership) And I didn't have to cut a hole in the tank. It was a easy install.
Bad 51, my tank is just a little different from yours I don't have the 2 holes in the top just one. the whole in my tank is just 1.75" id.(inside) I can Google the pump to get the dimensions. Do you know what the inside diameter of the wholes in your tank are. And does your tank have baffles?
