On your 68 1 ton does the fuel pickup go in through the top of the tank with the gage sender and use a rotating ring to compress the Oring seal? If so find a simular depth tank out of a later model GM - bet it'll bolt in and you got an instant in tank pump conversion with the correct GM fittings to run the line upto the TBI.. Marc
