ADJUSTMENTS



Electric fuel pump pressure is 28 psi. Fuel pump pressure is determined by a pressure regulator which diverts part of the fuel pump output to the gas tank when 28 psi is reached. The regulator, located on the engine firewall, has a screw and locknut on its end. Loosen the locknut and turn the screw to adjust the pressure. Do not force the screw in or out if it does not turn.
