fuel pump

[Dave]

Do I have to change fuel pumps in the tank if I put a 350 tbi and blazer that has a 4.3 tbi in it now? I know I will have to put an electric fan, motor mounts and possibly radiator. Oh yeah, what about the y-pipe? Will I have do anything to it?

I think the pump should be OK. Check with somewhere like AutoZone and see if they can give you the pressure rating for what you already have and what one would be for a TBI V8

All the TBI\'s run the low pressure,15psi, and the TPI use the high pressure pump, 45psi. You\'ll be just fine going with a TBI engine if your 4.3L was a TBI engine.

the y pipe should fit fine if you are using manifolds on your swap. Thinkin about using manifolds on my next swap just to make things easier. Greg
