Fuel pumps

What's a good size? I know with injectors they can't be too big; does the same principle apply to pumps?

Go with a 190 or 255, your fuel pump size doesn't matter because your fuel pressure regulator will control that!!!

I won't have a power adder for a while, it's my DD. so, can you have "too big" of a fuel pump? The price difference between the sizes is minimal so I'm just curious..

No you can't have too big of a fuel pump, your fuel pressure regulator controls the amount of fuel going Into the engine ! I would suggest a new fuel pressure regulator along with the new fuel pump

Re: Fuel pumps

The problem with a to large a pump is the unnecessary circulation of the gasoline. Too much re-circulation can heat up the gasoline which can cut performance and cause cavitation in the pump. The heat causes the gasoline to expand, meaning you can't get as much of it into the cylinder as when it is cold and the cavitation can introduce air bubbles into the fuel system.

I can see that. I'll just stick with stock for now until the time comes for 24# injectors, MAF, fuel pressure regulator, and dyno tune. Probably go with the 190lph pump.
Sound good?
