  • Running premix threw fuel water separator

    So I was wondering if you can run premix threw a fuel water separator and if I was able to could I leave my inline fuel filter connected also thank for the info.

    It would have to be a pretty damn fine filter to filter mixed oil out of the fuel.....

          A water separating fuel filter is like a man wearing suspenders and a belt. The suspenders might not be needed but he knows for sure his pants won't fall down.

          Given that fuel related issues are the number one problem with Yamaha motors you might be well served to have both filters. Think of it as very cheap insurance.

            I would definitly keep at least the fuel / water separator (10 micron).

              Mercruiser (I work at a dealership), who also uses a 10-micron, specs running the "fogging" mixture (which contains 2-cycle) through the fuel system for winterization. One of the ways to do this is by hooking up an external tank (with the ****tail mix) before the filter. Yup, you can run pre-mix through just fine. Think of it this way - if premix was LARGER than 10 microns, and a filter is designed to keep things out of the engine (that are 10 micron or larger), wouldn't pre-mix then be considered 'bad' for the engine?
