Do i need to upgrade the fuel pump???

[tbird187]

I am wanting to know if im going to have to upgrade the fuel pump, the car is a 91 ex 4 cyc car, still using the stock intank pump with larger feed and return lines, and a regulator to lower the psi, I know i dont need to worrry about psi but what about volume???

definitely man, the stock pumps are already problematic enough with a v8, i wouldnt try to use a 4 cyl version when swapping.

The pumps in most v8s last along time. Youve got to consider the age of them as well, most about 10-15 years. The pumps may be the same lph, but im not positive. Theyre really not all that expensive, so its soemthing that you could get over with now or just wait till that time comes

oh yeah no doubt, i'm just saying for performance reasons its a good idea to upgrade asap.
