Fuel System Question

[S197steve]

Hey guys, I'm currently running the Brenspeed Stage II Saleen kit which came with 39lb injectors. I'm thinking about getting some long tubes or cams but I'm not sure how I'll need to upgrade the fuel system.

I'd like to just get the FPDM Wiring upgrade (http://www.lethalperformance.com/05...09-mustang-gt-fpdm-wiring-upgrade-kit-p-15290) but I'm not sure if that will be sufficient. Would this be able to lower the duty cycles and provide enough fuel to safely tune the car?

I'd rather not have to get the KB BAP or GT500 fuel pumps right now as I'm writing a nice fat check next month to pay the car off.

You can do the wire upgrade your self, its pretty straight foward. Did mine for 15$, heres the info on how to do it,

And i would either replace the oem pump with a ford gt 255 lph pump or do a paxton add a pump kit which brenspeed sells.

which has the higher volume capability...the dual pump or the GT 255lph? i think the dual pump set would be the way to go...

..speaking of which, the GT500 fuel pump set up from what i understand is a pretty straight forward install...though the price may be a bit steeper.

I did my wiring upgrade myself, too, back when it was a v6 w/blower.
But, even being n/a and with the cams I'm running, the wiring upgrade is needed to keep it with enough fuel. When a blower goes on, the wiring upgrade won't be enough.
