I'll be installing a 6psi procharger p1x kit with a conservative tune on a stock engine. My tuner is thinking I should upgrade my fuel system. Hellcat injectors(Already ordered) and he suggests a walbro 450 fuel pump.

What is everyone doing for upgrading their full systems?
Am i going to have to drop the fuel tank to do anything with the pump?

I'm told the stock system is good to 600-650 ish. So you should have plenty of fuel for only 6 pounds. My stock pump has no problem with id1050x injectors and 10 psi

I went ahead and ordered a KB BOP for good measure. I'll run it and only have it come on at 3+ psi boost if that's possible

I ran mine with a Procharger D1S or a few weeks on the stock fuel pump. It worked fine. But I decided since my Jeep has 80k miles on it I would upgrade the fuel pump anyways. It's a good thing I did because when they dropped the tank they discovered an issue with a U-Joint on the driveshaft.

My dyno with stock fuel pump was 589hp.

does anyone know the wiring for our fuel pumps? Looking for a schematic or at least what color the power wire is

On mine, 2014, was a blue with orange stripe wire.

Hi,

I saw your post about being over 80K miles and upgrading your fuel pump. Did you upgrade to the Trackhawk pump? Was it plug&play then, tune?

Thank you!

Which pump did you eventually get

I ended up buying an OEM Mopar pump spec'd for the 6.4 68477870AA (68535771AA) running a gen2 MSD BAP with it.

how has it been holding up

So far, it's supporting my 5.7 gen5 Whipple build up to 10psi, I'm going to be cranking up the boost soon. Going thru tuning now.
