• Fuel starvation under load or at higher engine demand
• Low fuel pressure in carbureted gasoline systems
• Stalling related to inconsistent pump output
• Driveability issues from an aging OE-style fuel pump

Installation Notes and Tips

Verify inlet and outlet hose bead sizing before installation, and confirm the vehicle’s fuel system uses a 4 psi mechanical pump specification. Replace the gasket during installation and follow the included instruction sheet for proper mounting and fuel line routing. Confirm exact year breakpoints, including 03/1987 cutoff applications, before ordering for Dodge Raider, Dodge Ram 50, and Mitsubishi Mighty Max models.
