Description
When your electric fuel transfer pump starts acting up—losing pressure, running constantly, or not shutting off properly—chances are it’s the bypass valve giving you trouble. This little internal component is what keeps your pump from over-pressurizing and helps it maintain steady flow when you’re filling equipment. When it wears out, you’ll know it, and this rebuild kit gets you back up and running without replacing the whole pump.
What You’re Getting
- Complete poppet assembly that seals tight and responds properly to pressure changes
- Heavy-duty spring that maintains correct tension for reliable bypass function
- Bypass cap that threads on securely and keeps everything contained
- All OEM-quality components that match original factory specs
Built for Real Farm Work
This kit works on Fill-Rite 600, 1200, 2400, 4200, and SD series electric transfer pumps—the workhorses you see on farms and shops everywhere. These are the pumps handling everything from filling diesel tanks on tractors and combines to transferring fuel from bulk storage to smaller day tanks. Whether you’re running a portable setup or have a permanent fuel station, this kit keeps your pump working like it should.
Made to Last
These aren’t cheap aftermarket parts that’ll leave you doing this job again next season. The poppet, spring, and cap are built to handle the constant cycling and pressure changes that come with fuel transfer work. They’re designed to resist fuel contamination and maintain their seal even when dealing with today’s fuel additives and biodiesel blends.
Installation Notes
You’ll need to disassemble the pump head to access the bypass valve assembly, so have a clean workspace and keep track of parts as you go. The old poppet and spring usually come out together, and the new ones go back in the same orientation. A thin coat of clean fuel on the threads helps everything seat properly during reassembly.
