Fuel Transfer Pump 3936318 / 4988749 — Direct Fit for Cummins 6BT & 6CT8.3 Engines | Case 7110 & 9310 Tractors

The Cummins 6BT and 6CT8.3 are legendary diesel engines — built tough, long-lasting, and found in some of the most capable agricultural equipment ever made. The fuel transfer pump is what keeps the injection pump fed with a steady, consistent fuel supply. When it weakens, your engine starts hard, loses power under load, and puts unnecessary wear on the injection pump. This direct-replacement transfer pump restores reliable low-pressure fuel delivery, protecting your injection system and keeping your Case tractor pulling at full capacity through the longest days in the field.

✅ Compatible Engines & Equipment

• Cummins 6BT 5.9L diesel engine
• Cummins 6CT 8.3L diesel engine
• Case IH 7110 Tractor
• Case IH 9310 Tractor

🔧 Signs Your Fuel Transfer Pump Is Failing

Hard starting, loss of power under heavy load, rough running at high RPM, fuel starvation during long field runs, or accelerated injection pump wear are all signs your transfer pump is no longer keeping up. On Cummins-powered Case tractors, a weak transfer pump is one of the most common causes of injection pump failure — replacing it proactively is one of the best investments you can make in your tractor's longevity.
