Revive stubborn diesel engines in seconds! Engineered exclusively for Jo hn Deere 4040, 4050, 4055, 4240, 4250, 8570, 9400, and 6081H tractors, the SUGGESGIVE JN Hand Primer Pump seamlessly replaces worn-out RE65265 units.

Forged from cold-forged brass and chemical-resistant polymers, it withstands diesel exposure, vibration fatigue, and -30°C freezes without cracking. The oversized T-grip delivers 30% easier pumping force versus stock pumps, reducing hand strain during extended priming. Direct bolt-on installation reuses factory fittings—no modifications! Stop cranking dead engines and restore reliable starts in blizzards, harvest season, or dusty fieldwork.
