Description
If your fuel transfer pump is losing prime or not moving fuel like it used to, chances are the diaphragm needs replacing. This is one of those wear parts that takes a beating from constant pressure changes and different fuel types, but when it starts to fail, you’ll know it right away—either from poor fuel flow or fuel showing up where it shouldn’t.
What You’re Getting
- Complete diaphragm rebuild kit with all the seals and gaskets you need
- OEM-quality materials that handle diesel, gasoline, and other approved fuels
- Restores proper pump performance and eliminates fuel leaks
- Everything needed to get your pump working like new again
Built for Real Farm Work
This kit is designed for Fill-Rite 400B Filcon fuel transfer pumps, the workhorses you’ll find on fuel trailers, tank trucks, and stationary fuel systems around farms and construction sites. These pumps see daily use moving everything from diesel for the tractors to gasoline for the trucks and smaller equipment.
Made to Last
The diaphragm and seals in this kit are built to handle the chemical properties of different fuels while standing up to the pressure cycling that comes with pump operation. Quality materials mean you won’t be tearing into the pump again anytime soon.
Installation Notes
This is a straightforward repair job if you’re comfortable working with basic tools. Take a few pictures before you start disassembly—it’ll save you time when putting things back together. Make sure all fuel is drained and the system is depressurized before starting work.
