Hey guys

Will I need an adjustable FPR if I install the double pumper on a stock fuel system with 1200cc injectors on e85? I know I will need one of I go with a 400lph so that is factoring into my decision. I'd like to keep the stock FPR if I can. Thanks guys

Fred

 

twin 255 pumps with the reliefs pushed in ''as most BR DP'ers come'' you wil lbe just fine with the stock FPR.

 

Sweet thanks Dan! The double pumper will give me more headroom so that's great

 

RS: With the BR Double-Pumper, the secondary pump is staged, as opposed to some other double pumpers wherein both pumps are on full time even at idle.

 

That makes sense. Thanks sparky!

 

Will I need to Rewire the pumps for more voltage to get the double pumper to work properly?

 

Interesting thread. Never know when to get a better FPR or fuel rail for that matter.

 

I was told i wouldnt need a fpr with a 400lph on the same size injectors. are you posative you need a fpr for a 400lph?

 

What turbo, Fred?

 

Sparky, I'm running the ATP stock-location gt35R

 

Sktng22, from the research that I've done so far, most of the guys who go with a 400lph overrun their stock fuel system. Also, the walbro dealers/vendors have a disclaimer that says the AFPR is highly recommended with the big pump.

 

no rewire needed either unless its twin 400s. 255s your fine

 

Don't you mean just the opposite, dan? That is, with the lower volume 255's you may need the 13.8 volts. Probably, I am not understanding your statement though.

 

With twin 255s a re wire is not needed. I am not saying it won't help but its not needed. Many guys running without a rewire. There is plenty of fuel in the system.

400+lph pumps seem to need one. Why I don't know. Maybe the pump is drawing to much for the factory wire? Or is requiring more volts to run properly? Again Idk

 

Thanks, Dan.
