Engine Compatibility
Suitable for gasoline-powered engines and fuel systems where a storage stabilizer is needed. Best positioned as a general gasoline fuel stabilizer for marine, small-engine, and other gasoline-powered equipment that will sit between uses.
Serial Number Fitment Notice
This product is a fuel treatment rather than an engine-specific hard part, so serial-number fitment is generally not the deciding factor. The key check is confirming that the application is gasoline, since the SDS identifies KLEEN-FLO 790 specifically as a gasoline additive.
When This Part Needs Replacement
Use this fuel stabilizer when gasoline will be stored for an extended period, during off-season layup, or any time you want to help preserve fuel quality before equipment sits unused. Kleen-Flo's product claim specifically centers on extended storage and easier starting the following season.
Installation Notes
Add according to the product label directions for the fuel volume being treated. Because this is a chemical fuel additive, follow the container instructions and standard fuel-handling precautions. The SDS classifies it as a consumer product gasoline additive and provides current safety and handling information for normal use.
Alternate/Superseded Part Numbers
The manufacturer identifies this product by code 790. The retail package is listed as 790 350mL 12, with no current evidence of a superseding product code.
Parts Desk Insight
Fuel stabilizer is one of the easiest preventative items to overlook during seasonal layup. For boats and other gasoline equipment that may sit for months, using a stabilizer before storage can help reduce fuel-related starting trouble when it is time to get back on the water. KLEEN-FLO's positioning is straightforward: keep fuel fresh during storage and support easier starting next season.
