So I'm about to order my sending unit for my k5. I'm going to be running a carb for now bit might eventually get a ls or do fast TBI conversion. Anybody know if I can change the in tank pump to a higher pressure pump? The stock tbi pump is 14- 25psi. If I were to go to a faast TBI I nneed at least 45 psi. Would a in tank pump work from a 90's vortec chevy?
