Looked today, its empty thank goodness. So I will put in 25 gallons this week and new fuel filters. I have the big NAPA 4348 filters on it now.

So, your engines actually can't start or barely run because your tank is empty ?

No, in terms of running, it could run, its just barely on "E" . In terms of pumping out 50 gallons of old fuel, at least I wont need to....
