fuel pump limit on a 90 L98
My planned mods are:
SuperRam (I have)
accel/Lpe 219 cam (not yet)
Trick flow heads (i'm ordering..)
hooker LT headers (I have)
with the mods I have already (in my sig).
Do you think I need to update my perfectly working in tank Fuel pump?
I know that on 84 models the first thing to change is the fuel pump when yuo upgrade the engine, but i never heard of it for upgraded L98 engines...
Thanks in Advance

Anyone that has had an improvement by upgrading the pump, would have had the same improvement with a stock pump, because they NEEDED a pump.
