to piggy back
since my episode of pressurizing and draining, i have had zero issues with WIF light.
but i drained, pretty close to 2 galons of fuel. you may have to go through the drain,install a new filter, install cap and do the key on x3 to refill it, drain again, key on x3 again, drain, do this untill its pure fuel running out no littl epieces or gell, then change out the filter once again.
its expensive -mad , oriellies here has fuel filters for the best price, but warranty will not cover bad fuel, it only takes a little bit of water to screw it all up.
we put in 8 oz of power service now at every Full fill up over 30 gallons.
i geuss its making a big difference, i ahve had no more lights or fuel issues.
