fuel pump too big??

lx5091 · 08-13-2002, 11:10 AM

Hey guys,

I have to drop the gas tank and find a leak and maybe replace the tank. I'm figuring since I'll be there, I might as well install a fuel pump. In the future the mods that I will be doing will require a 155lph-190lph, can I install this now even though my mustang is as stock as they come. I would think that it would burn itself out before I got any mods in. What do you think?

I'm pretty sure it will be fine
I don't think you can burn these pumps out by not using enough fuel.
The only other thing you may need to worry about is the pressure regulator. I think most guys get an adjustable unit but you can run it on the stock unit.

The fuel pump will be fine putting out less than the maximum amount. In fact you only use the maximum fuel on high speed passes with nitrous or a poweradder. Like Conman said though, you should put in an adjustable fpr or your new bigger pump may put to much pressure on your stock regulator or injectors.

Makes sense guys.

Thanks for putting a little perspective on it for me.
