Pumps are preset @ 14 PSI, with a free flow capacity of 110 GPH and a flow rate of 70 GPH at a steady 9 PSI. Pumps use an externally accessible pressure relief valve and weigh only 3 lbs. Serviceable from either the pump end or the brush end. Regulator P12-803 included to reduce your fuel pressure to the required 6 to 7 psi range at the carburetor.
