IMPORTANT:
12V electric fuel pump with solid-state control and 1/8"-27 NPT fittings. Self-priming capability up to 12 inches of fuel lift. Fits John Deere 5000 Series tractors: 5200, 5300, 5400, 5500 confirmed models (1990-2026 production span).
Failure symptoms: no priming buzz when key is turned to ON position, hard starting, engine stalling under load, fuel starvation at high RPM. The solid-state control module can fail independently of the pump motor — test for 12V at the connector and listen for pump activation sound before condemning the entire unit. NPT fittings require thread sealant (Teflon tape or pipe dope) during installation — do not overtighten.
⚠️ Confirm 1/8"-27 NPT thread size matches your fuel line fittings.
