Over the past year I've been slowly trying to improve my engines performance output. Squeezing every little hp out of it I can. I've been wondering lately if its getting enough fuel. I'm still running the stock fuel pump. My car is pushing about 300rwhp right now. Should I upgrade? If I had to upgrade I would prefer a mech. pump. I've heard rumors it won't pull through the existing intake pump, true? The car is carbed with a 750dp at 6psi.

 

Those in tank pumps move some fuel, hard to beat. The mech. puller pumps are some trouble in hot weather from what I've seen. I say stick with what you have.
