High Pressure Electric Fuel Pump

Multiport EFI systems require a stable fuel supply to maintain best performance throughout the engine's rpm range. This high pressure and high flow Fuel Pump features a roller vane pump mechanism which is extremely resistant to clogging and jamming. The pump mounts in-line (out of the fuel tank) with two supplied cushioned clamps for a quick and sturdy installation. The nipple inlet is 3/8" with a 5/16" outlet. The wire terminals feature brass studs for secure connections. Made in the USA, the pump is ideal for use as a "booster" for nitrous oxide applications, or as a stand alone pump for multiport EFI systems on engines up to approximately 500 HP. Capable of 43 gph at 40 psi.

Approximate flow is 43 gph (282 lb/hr) gasoline (specific gravity 0.788) @40 psi and 12 volts/5.4 amps. Has 3/8-in. hose nipple Inlet, 5/16-in. hose nipple Outlet. Includes 2 cushioned mounting clamps and 4 mounting bolts.

When the supply voltage is maintained or increased, the fuel pressure and flow of the pump is maintained.

Fuel Pressure Regulators

Maintaining accurate fuel system pressure on any multiport EFI system is crucial to performance. MSD's Adjustable Fuel Pressure Regulators allow you to fine tune the fuel pressure to meet the demands of your engine and injection system. Both Regulators are adjustable from 36-45 psi with a flow rate of 9.2-10.5 gal/hr. The inlet and outlets are 5/16" and a jam nut is supplied for special threads on the bottom to ease mounting to a bracket. These rugged Regulators are free standing so they don't have to be mounted directly to a fuel rail and can be installed in any position. Fuel pressure is set with an adjusting bolt and is locked in position with a locking nut.

Boost Adjustable

This Regulator is designed for turbo or supercharged engines. As boost pressure increases, more fuel is required by the engine. This regulator features a boost reference circuit that adds more fuel in relation to boost pressure.

Fuel Pump Booster

Adding a turbo or supercharger to your engine is a great way to improve the power of your car. But you have to remember that when more air is being pushed into the engine, the need for additional fuel raises proportionally. Meeting these new fuel demands could mean larger injectors or ECU programming, both which can be pricey. This new Fuel Pump Booster is the economical (and easy) answer for your engine’s new fuel demands.

The Booster will supply the electric fuel pump with increased voltage in relation to the manifold boost pressure. As boost pressure increases in the manifold, the MSD Booster will increase the voltage to the electric fuel pump. The amount of voltage is adjustable with a potentiometer from a range of an additional 1.5 volts to a maximum output of 22 volts over a range of 5 – 30 psia.
