Fuel pump recomendations
Stock vehicle: '91 4.3 TBI
New engine: ~350HP Vortec 350 (w/TBI from 7.4L BBC)
My stock pump is just not up to snuff. Fuel pressure at idle is ~23PSI (roughly where it should be), but hitting the throttle just standing there, it's dropping to about 13! Uhhhh... not good.
I can get a new in-tank pump from various cars.
Is one from an MPFI setup that ran stock about 50psi about what I'm looking for? Any one in particular that's better than the next?
