Holley EFI Filter Regulators

When converting your fuel system to a return-style EFI setup, the biggest challenge can be plumbing the fuel lines. Holley has found a way to make this job easier! They offer EFI filter regulator assemblies to simplify your installation—by combining the fuel filter and regulator in one unit that can be mounted in the rear of the vehicle. Mounting in the rear means less line to run for a return and less mess. These regulators feature a 175 gph, 10 micron fuel filter built-in. The regulators are preset at 59.5 psi. They're available with 3/8 in. NPT or -8 AN port sizes to match most common EFI fuel systems. Simplify your EFI conversion, or clean up the plumbing on your current EFI system, by installing a Holley EFI filter regulator. (Diecast EFI fuel regulators are also available by Holley.)

Holley Safety Fuel Pressure Switches

It's always a good idea to place a safety switch in the circuit when installing an electric fuel pump. Holley safety fuel pressure switches will ensure the electric pump will not work unless the engine has oil pressure. It will prevent the pump from running in a situation where the motor may stall with the ignition on. Wiring the switch through the starter solenoid circuit energizes the pump on engine start-up. After the engine is running, the switch continues to provide power to the pump as long as there is oil pressure to keep the switch turned on.

Holley Fuel Pressure Regulators with Pulse Damper

Holley fuel pressure regulators with a pulse damper offer several benefits for performance and reliability. Fuel pulse dampers are designed to act in tandem with the fuel pressure regulator to further control the fuel pressure in an EFI system. These devices help stabilize fuel pressure by absorbing the pressure fluctuations (pulsations) caused by injectors opening and closing, and by the fuel pump. This leads to smoother fuel delivery, improved engine performance, and can help prevent lean spots that can cause stumbling or hesitation, especially during acceleration. Features: * Engineered to stabilize pressure pulsations caused by the injectors opening, ideal for applications with large fuel injectors and high-volume fuel pumps * Compatible with any fuel—full anodized billet aluminum construction with stainless steel springs and Fluorosilicone diaphragm * Fittings included for damper/regulator's and direct mount dampers * 1/8 in. NPT port on body for easy installation of mechanical pressure gauge or pressure transducer/ * Vacuum fitting and one foot of hose included with all dampers for vacuum referencing

Holley Ford 7.3L Godzilla High-Pressure Oil Pump Springs

For certain applications, higher than normal oil pressure is required. Typically, the oil pan must be removed to change the pressure spring on an oil pump. The Holley oil system allows direct access to the spring through the access port on the bottom front of the pan. Holley's high-pressure spring for Ford 7.3L Godzilla engines with their oil pump and pan can be purchased and installed to increase oil pressure by approximately 10 psi at higher rpms. To change the spring, remove the port plug, spring, and plunger. In some cases, the plunger may stay in the port. Make sure when reassembling the plunger is on top of the spring and oriented correctly.
