Where can I get a new fuel pump for an RX1 with an MPI stage One supercharger?

I have one similar to this Walbro unit. You are using a fuel pressure regulator aren't you ? Whatever you get you need high pressure and high volume so you never starve the engine when the boost is up.

I have the one that came with the kit. There have been no problems for years. This year,there are times it is missing. Last weekend it would die after a couple hundred yards. The sled will idle forever,but when I hammer on it,It shuts off. Was hoping that the fuel pump was bad, but i did a pressure check last night. It has 10 pounds of pressure at half throttle. I can't figure out if this is fuel,or electrical.

4.5 pounds at idle and it should add 1 pound per pound of boost as it builds. That's with a turbo and I don't know why it would be any different with the SC,
it's still carbureted.

I guess im wrong I thought that's what the guy from full power performance told me
I agree with Givemeaboost on 4.5lbs, fuel pressure reading is taken before the carbs. As the regulator knocks the pressure the pump will make.

I guess it was probably 12-14 at full throttle that would make sense

Fixed. Power lead to the pump was broke. When I was doing wheelies it would loose contact. That was hard to find. Thanks everyone.
