This regulator is totally adjustable from 30-100 psi.This adjustable fuel pressure regulator is made from all new parts and has two O-rings internally, so it will never leak. Any adjustments can easily be made without removing the vacuum line since the adjustment is a separate port on the top.

One big improvement is it has a larger feed and return fittings internally for 30% more fuel flow, which reduces restriction of the regulator. If necessary, the unit can be rebuilt as we will offer diaphragms separately.

Each unit comes with new hardware to attach it to the fuel rail. This adjustable fuel regulator can not only deliver 75 pounds of pressure, but it can also be set below stock fuel pressure, if you run fatter injectors.
