alright buddy, i'll give this a shot. for the pulley i took a few pics for ya. mine was a factory a/c truck that i took the compressor off of but left the brackets. the pulley on the p/s pump is 1 1/4 thick and 5 3/4" in diameter. heres the pics of the brackets.







now for the fuel... on the tank the ports are a sending unit. there isnt a pump in there unless its been switched to an electric pump. the should be only 2 ports, 1 for fuel feed that goes to the fuel pump on the engine block and the other goes to a charcoal canister mounted under the hood on the driver side fender or core support. heres a couple pics of mine...

vent line...



now if your new motor has a manuel fuel pump which it should then you can plug off the 3rd port. hope this makes sense and helps. Dennis
