Wondering if this is a place to reduce restriction in the stock system?

I see K&N offers one.

I am at or near the maximum for the Racetronics 255 pump with hotwire.

I have made 565 rwhp with it and expect just over 600. Hoping I do not need to do a whole fuel system, though I know that is a possibility.

Thanks for any input.

In for answers as I have the same issue with the 255. I searched before for the same thing but couldn't find anyone that really tested each one. I've just been using ac delco.

Why not just upgrade the pump to a 320 or 340, whats your duty cycle now?

Hoping not to upgrade as I have a 7 day race in 4 weeks. Hoping to be running this weekend. Running all new fuel lines would not be time friendly.

Have a ton to break in as well. Clutch, diff, motor etc!

I made 700whp through the auto with a Mann brand fuel filter

And if you are worried about running out of pump, ditch the 255. I am running a single 450
