Gastank conversion fron intank pump to mechanical, on engine pump

[av8tr33337]

I hesitate to even ask, but I think I have seen some reference to this in sombodies build thread. Im using a 1984 Carberated 305 with a mechanical on-engine fuel pump on my build. The guy who owned my 94 S10 Chassis before I got it, removed the in-tank pump and left me with just a shell with no inlets or lid, etc. I Know I could replace all that, but I would like to use the mechanical pump. Does any body have info on how to convert the 94 S10 gas tank to allow me to do this??? I.E. creating a pick up system with Screen etc. Do most gas tanks have the same type of lid, etc to where I could slap an older "pick up style" lid on it?

Thanks in advance
