Videos (1)
The Marty's Diesel OBS E-Fuel Bosch kit converts 1994-1997 Ford 7.3L OBS Powerstroke trucks from the mechanical lift pump and valley fuel bowl to an electric pump with external filters and a regulated return.
It ties into the factory selector valve so both tanks still work, and it feeds the rear of the heads through the factory rear lines, so the stock turbo stays in place. Marty's lists the Bosch 69136 pump as tested up to 180cc/30 percent injectors.
- Electric Fuel Conversion: Replaces the mechanical lift pump.
- Fuel Bowl Delete: Removes the leak-prone valley bowl.
- Keeps Both Tanks: Integrates at the selector valve.
- No Turbo Removal: Reuses the factory rear feed lines.
- Complete Wiring: Relay, breaker and Molex terminals.
Technical Specifications
- Kit: OBS-E-Fuel-Bosch
- Manufacturer: Marty's Diesel
- Pump: Bosch 69136
- Injector Support: Up to 180cc/30% per Marty's
- Hose: Parker 801 push-lok, crew cab long bed length
- Bracket: Laser cut stainless steel
Vehicle Fitment & Technical Installation Notes
- Fitment: 1994-1997 Ford F-250 and F-350 7.3L OBS Powerstroke. California emissions trucks also need the Marty's California plug, T4 turbo setups need different fittings, and regular cab 4x4 trucks mount outside the frame rail.
- Installation Tip: Hand tighten any NPT fittings in the heads, then go only 1.5 to 3 more turns with clean ports. Overtightening can crack a head.

Purchased the OBS e fuel kit and it showed up extremely fast and everything was packaged well and high quality. Definitely recommend full force diesel and this kit for anyone that has a stock fuel system on their 7.3.
