Weber Fuel Pressure Regulator
(1.5-12lbs)
The regulator's job is to keep the pressure in the fuel system at a constant psi. Your Toyota fuel pressure regulator controls the amount and speed at which fuel is used by your vehicle. A faulty fuel pressure regulator can cause poor fuel mileage, rough running engine or starting problems. This is a simple way to keep your fuel system running right. Weber carbs work best in the 2.5-3psi range.
NOTE: The factory fuel line from the mechanical pump is roughly 1/16" smaller than Weber Regulator/Carb fuel line. Slight pressure is all that is needed to fit the smaller line. If you're running the Weber electric fuel pump, see Part #: 1035046. If your application is a boosted blow thru carburetor setup, see Part #: 1035059.
