Product Overview
An EFI Sportsman that cranks but will not start, loses power under load, stalls hot, or no longer gives a normal key-on prime may have a fuel-pressure problem. Once voltage, relay operation, injector pulse, tank venting, and actual pressure are checked, this assembly replaces the in-tank pump module on matching six-bolt tanks.
Seller fitment lists for early Sportsman pumps conflict, so the original part number and six-bolt flange pattern are the deciding checks. Clean the tank before installation because dirt or degraded fuel can quickly damage a new pump.

Frequently Asked Questions
Q: Does this fit every 2005-2007 Sportsman 700? A: No. Use the original number and six-bolt flange pattern because listings and production setups vary.
Q: Can a bad relay look like a failed pump? A: Yes. Check power, ground, relay output, and pressure before replacing the module.
Q: Why clean the tank? A: Water, rust, and degraded fuel can restrict the pickup and shorten the life of the replacement pump.
