You can get a Racetronix fuel pump (Walbro 255lph pump) for 150. You will be reusing your stock sending unit and you have to trim the ribs inside your fuel bucket, but it's an easy install. That pump will support something like 700hp.

will it be to much for a stock motor? I heard that you need to splice wires and stuff with that maybe im wrong. what about a walboro 255lph?

It will be fine for a stock motor and it will leave room for future mods. The fpr will regulate the fuel pressure in the rails, hence the name, lol.

Just as my post says, the Racetronix kit uses a Walbro 255lph pump. You don't have to cut and splice any wires. You do, however, have to trim the fuel bucket a little. There is a write-up somewhere around here that I followed, install is a snap, especially if you do the trap door method.

Yea, you don't have to re-wire anything with the kit, direct swap. I'm running it in mine.

Here is a good pic for a trap door..this is what I did.
