Anyone ever use this fuel system treatment? It has nothing but good reviews. I put a can in my Land Cruiser and it really made a difference. When I change the cool fuel filters, I’m going to put a little in the module directly to give the injectors a good dose and 2 cans in each tank. It’s on sale now also on Amazon.

    I would be careful putting it directly in the module itself.  Someone on my dock did the same thing last year with  seafoam and had issues right away. I believe the product is meant to be diluted. You can maybe run a richer dilution but I would probably not run it directly in the cool fuel module itself.

    I wasn’t going to put a lot in the module just a splash. But I probably won’t now.

    I'd also be careful if still have the original cool fuel modules, as they were known to have the coating inside flake off (mostly due to ethanol).  I'd just make sure this would effect that coating.

    @Dream_Inn both of my modules have been replaced.
