Manufactured for carbureted street and maximum performance/race applications, these electric fuel pumps and regulators are made to the highest quality standards. They're machined from aircraft quality aluminum to aerospace tolerances for extended life and performance. The pumps are available in both a 120 gph and 160 gph (gallons-per-hour) configuration. The 120 gph pump (good for 600 HP) preset at 6.5 psi so no regulator is needed. The 160 gph pump (good for 1000 HP) requires the fuel pressure regulator, which has 3/8" NPT inlet/outlet and is adjustable from 5-10 psi. Premium performance fuel system components from Edelbrock.
