Fuel pressure

[scrawny]

I believe the stock fuel pressure is around 40ish. Does anyone know what it is after the FPR mod with the BB??
Thanks

65-75 psi with the BB. But you really need to check it with a gauge after shimming. Some guys have reported pressures as high as 85-95 psi with the BB installed. You can also use a cap screw with a small brass nut behind the spring for an adjustable version of the FPR mod.

FPR Shim Article.

Yeah what he said. Don't go shimming the fuel pressure regulator without a gauge. Running too much pressure is not a good thing..
