    I don't know a definitive answer to your question, but consider this. you will need to use a block off plate where the mechanical pump goes, Is it the same as a small block, so you could just use an SBCs? Is a block off plate even made if not an SBCs? Can you make one? the pump is on an angle if I remember correctly and is bigger than on an SBC. you will need a regulator. I believe the mechanical pump only delivers the fuel to the electic pump on the intake at a very low PSI, then the electric gives the injectors the proper PSI. I would think that if you had the regulator for your added electic pump calibrated perfectly, you could get away with it. but for 20 bucks for a new mechanical pump, maybe just replacing it would be best.........js

    Oh the pump on the intake is an eletric, I thought it was mechanically driven also. Anyway I'll give a new mech. on the block a shot. Thanks for the information

    I, would get rid of the mech fuel pump. You can buy the plate from Chevy. Oneday, buy yourself a good inline electric pump, you won't have any complants. It helps when you change filters, or run out of fuel! GOPHERKILLER
