f4 excell with tank under front deck. so when it gets down to about an inch left it runs out of fuel; pickup tube isnt all the way to the bottom... seem to be having water issues ( who woulda thunk it) -problem is i cant seem to get all the fuel out which has to be water laden. tried blowing air into fill hole, tried just pumping bulb, decided it aint coming out without pulling tank which is virtually impossible per the factory!!! very frustrating is there a product that will evaporate the water in the fuel left inside the tank? is there a way i could drill a drain hole and a product to insert as a plug/ drain that would hold? ? dont want to ruin the tank but tired of draining the f/ w seperator, and having a crappy running motor thx if you can help
