Default Fuel pump question

If I try to go bigger than a 75hp shot on my nitrous system my fuel pressure cut off switch turns off my system. Does anyone sell a hi output fuel pump or do I need to put a second pump in line? My fuel regulator is opened all the way and my nitrous system is gets it's fuel from the schreader valve on the fuel rail.

Go to racetronix and get a 255 Walbro.

There is new High Performance In tank EFI fuel pump out on the market now worth checking out..........

Made by Areomotive.
The Stealth series fuel pump.

I seen it on display at the Chicago Drag Expo this past winter.

It flows much more LPH or GPH than the Walbro 255lph and is competitive in price.

Fits in the stock fuel pump hanger where the AC Delco FP usually resides.

I picked up the "Stealth" EFI fuel pump and examined it closely.

Its heavy for its size.
That tells me it has Heavy Duty Permanent Field magnets and stout Copper wound armature within.
Nice Anodized Smoke Black- Gray casing.

I believe the Stealth EFI pump flows somewhere around 350LPH @ 45psi.

I have the flier around here somewhere on the Stealth pump I picked up from the Chicago Drag Expo on it.
I'll Look for it in the morning.

guys when I change this pump is there a kit that can also deal with the fuel slosh in our tanks when we turn. As long as I am in the tank I might as well deal with that issue also. How do you get to the fuel pump to remove it from the tank, is there an easy way of doing this or is it an all day kick in the boys?

Take the fuel filler lid off (4 torx screws). Remove the fuel line clamps and hoses. Remove the zillion 10mm head bolts holding the top of the fuel tank. Disconnect wires and pull the whole unit out. A fuel cell will let you run till the last drop. I put a 5 gallon in my car for bracket racing.

no one out there has come up with a DIY on how to fix our fuel slosh problem when taking corners with less then a 1/4 tank of fuel?

The easiest way to avoid fuel slosh is fill your Vette up with 93 octane or 110 race gas.

Works great.
