Fuel Injector For HiSun EFI 500 & 550 UTV/ATV - Fits Massimo, Coleman, TSC & More

Got a HiSun, Massimo, Coleman, or similar 500cc or 550cc EFI machine that's running rough?

This fuel injector might be your fix.

It's designed for a bunch of popular UTVs and ATVs, including the HiSun MSU500, the Massimo 500, the Coleman 500, and even some TSC and Bennche models.

The OEM part numbers are 16400-004C-0000 and 16400-004-0000, so you can double-check compatibility.

Now, a quick heads-up: this part is brand new and has never been used, but because it's been in storage, it might have some light scratches or marks.

Nothing that affects function, just cosmetic.

It's a genuine replacement that'll get your fuel flowing right again.
