Plug and play 03’ Cobra pumps

[JamiesonKid3132]

Can I run these pumps in my stock hat? My pumps are original from 02’ and although the car only has 17,000 miles it’s time for new pumps.

Simple question, will these 340 pumps work in my stock hat with no mods?

You would need a tune to run those pumps. Only stock replacement pumps work with the stock tune.

I should’ve added the car is tuned, I assumed a re tune will be necessary.

I think anytime you run aftermarket pumps with the stock hat you're just asking for problems.

And you will need either dual FPDMs or a Black306 FPDM but not sure if the 306 is enough. You can get to 650hp on a black306, dual supercar pumps and a wiring upgrade.

If you want to replace the stock pumps, best bet would be a full replacement hat from RockAuto. Plug and Play and will last another 20+ years if you don't plan on adding more boost.

If you want to turn it up, then it's time to look into a good return style fuel system.

I’m going the ported Eaton, bolt ons with full exhaust route and aiming for 525-550RW with my Cobra on 94.
For fuel I’m upgrading my injectors to 60s and installing the dual supercar pumps with proper lines and clamps.

I feel it’s enough additional fuel for my needs.
If I was going Whipple etc and 600+ I would be installing a proper fuel system to support it.

Adding GT Pumps to the stock hat is not ideal. First, the wiring is too small to support the extra load that the GT pumps draw. Second the outlet from the hat needs to be larger to take advantage of the extra flow rate. Third, you will need to upgrade the FPDM to either a Modded one, or better, Dual FPDM setup. Better bet would be to go with a Fore Hat designed for the GT pumps and upgrade to the Dual FPDM setup. This will work perfect like OEM.

Thanks for the info.
I will look into the Fore hat.

I have a Fore returnless hat that I'm not using anymore if your interested. I recently switched to Fore return setup. The hat is complete with gt40 pumps and the fuel line adapter already on it.
