Got a HiSun or similar EFI 500 or 550 UTV or ATV with a fuel issue?

This is the injector you need.

It's a genuine new part that was never used, though it might have some light storage marks.
![]()
It fits a ton of models under different brand names: HiSun, Massimo, Coleman, Qlink, TSC, Bennche, and more.

The main part numbers are 16400-004C-0000 and 16400-004-0000.

If you've got a MSU500, HS500, or similar 500cc/550cc machine, this should get you back on the trail.
