Elec. Fuel Pump Module EFI In-Tank 73-86 Jeep

The Elec. Fuel Pump Module EFI In-Tank 73-86 Jeep by Holley is purpose-built for classic Jeep enthusiasts converting carbureted fuel systems to modern electronic fuel injection. If you're upgrading a first-generation CJ-5, CJ-7, or full-size Cherokee to EFI, this in-tank module eliminates the need for external fuel pump housings and delivers consistent pressure for reliable cold starts and high-load performance. Holley's integrated design simplifies wiring and reduces installation complexity on vintage platforms where engine bay space is premium.

This in-tank fuel pump module combines a high-flow electric pump with integral fuel level sensor and pressure regulation in a single sealed assembly, eliminating troubleshooting headaches from mismatched components. The design pressurizes fuel to EFI-spec levels (approximately 43–48 psi) while the onboard regulator prevents fuel starvation during sustained acceleration or off-road driving. Mounting directly inside the factory tank minimizes external plumbing runs, reduces fire risk, and keeps fuel cool—critical for carburetor-to-EFI conversions where stock systems lack proper regulation and pump capacity.

Mechanics and restorers working on 1973–1986 Jeep models benefit most from this module when pairing it with Holley EFI engine control systems or standalone ECUs. Installation requires tank removal and basic electrical integration, making it ideal for restomod builds where modern driveability and cold-weather reliability matter as much as period-correct aesthetics. The compact form factor (8.4 × 8.2 × 13 inches) fits original tank geometry without modification, and the 2.3 lb weight has minimal impact on vehicle balance.
