Secondary Fuel Pump

[Guero]

The Fox came with a secondary fuel pump for the S/C.. but it has a stock pump... If I install a 255 can I remove the secondary pump? It will be less things 2 worry bout if it breaks of something

I would keep the t-rex... With the T rex and a 255 you should be good to around 600 horse.. That way if one DOES go bad, the other will should keep you running..

I dont plan on pushing 600hp.... Im only gonna do Bolt-ons and 12lbs of boost....Do I need it?

Did you say you were keeping the iron heads?

If so then the 255HP will be fine for you. Any more and the T-rex becomes very helpful.

My personal car topped out a NON HP 255 around 380rwhp-ish. I added the TREX and the pressure is solid now.

To know for sure, find a way to log your fuel pressure at the rail and watch it alongside the boost. Most tuners will do this for you on the dyno (hint, hint).

up to 600.. If you already have one, why are you so afraid of using it? I truly like the idea of twin pumps..

The only reason I might consider NOT using it in his case is because of the heat where he lives and the recirculation heat/pressure that builds up.

But I am also on the side of the fence that says I'd rather have too much fuel than not enough.
