How much fuel pressure do you need?

FB II

not fully sure yet. i just know i need it to work with atleast 8 lbs of boost on a carb'd motor.

Yes, it'll work but you still need a fuel pump.

yes, that should be more then enough.

That's not a RRFPR. In the description it says "Features include a 1:1 pressure rise when referencing boost." By definition, a Rising Rate Fuel Pressure Regulator was a rising rate, ie (2:1, 3:1, 5:1, etc.). All FPRs reference manifold pressure, so almost all will work for both turbo and non turbo. (Note: there is usually a limit to the highest manifold pressure that it can handle, this one handles up to 25 lbs)

But you don't want a RRFPR, that what getto EFI turbo setups use, when they can't properly tune the engine to run the boost they want. Carbs can't use a RRFPR, period. They'd overflow the float bowls every time you hit boost.

Then what would you use for a turbo fb? Not the stock fuel system???

I would have to disagree with you fatboy7.

What are you basing your opinion on?

I have a turbocharged carbeurated car with a RRFPR and have never had a problem with overflowing the float bowls.
