Upgraded Fuel Pump?
A friend of mine recently purchased a Paxton for her V6. The kit includes larger injectors. When I datalogged for her, I discovered the fuel pump is attaining 100 percent duty cycle at the top end.
I was thinking the GT pump may be better but just found out it is the same as the V6 pump! What are the options for a larger capacity fuel pump?

Faber turned me on to this - he did it on his car, I did it on mine in prep for e85:

It's only good for about 10% reduction in duty cycle, but it's cheap parts and goes together pretty quick. I already had the wiring in the back for the amps, so I just hooked into that with some 8 ga wire. Got the relay from Merles.

Thanks for the info guys. Chris, I've done something very similar on my (former) IROC-Z but instead of wiring to the battery, connect it directly to the alternator output. This results in the most voltage you can humanly get to the back of the car. It's an old Chevy trick..... oh, that's why no one here knows about it...![Rollinglaugh](https://themustangsource.com/forums/images/smilies/rollinglaugh.gif)
