2015 Cougar FTDThis has happened several times….Ill run the port tank down until the motor stops so I can see where my fuel gauge reads….motor stops usually at around 1/4 tank!The last two times I did this I decided to fill the tank to see if it actually holds 26 gallons!I can only get 13 gallons in before it tops out! Two times in a row….13 gallons!Whats up?
