Fuel Pumps - Which One?!?!?!

[tjm73]

I tried searching here and elsewhere, but I can't find any info that would allow me to figure out what size fuel pump would be proper for my car. I expect it to have about 375-400 flywheel hp, but closer to 375 I think.

Anyone know where I can find this information?

255lph,there all close to the same price,so buy the big one.

Is too much fuel pump bad? Like too big a set of valves in the heads or too large of a carb would be?

No.
A bigger fuel pump is good.

I mean it is possable to go to big,like you wouldnt need a A1000,that would just waste power.

But a 255lph is perfect because of the more volume of fuel,which also help keep the fuel cool in the line if its at the same pressure.

Fuel system is return style, so all the extra fuel just ends up back in the tank anyway. Might as well get the big one and only do the job once.

The only problem with going with something like a 255lph fuel pump is it draws more heat in which it is recommended to not let the tank run to low to keep the surrounding gas as a "cooler"...

I run a Walbro 190lph fuel pump in my daily driver...the 255lph would be fine for ya though...
