Fuel Tank -16 gallons.....why can I only put in 10 gallons?

Try filling up, and run it to 3/4 tank, fill up again. Repeat sequence for 1/2 tank and 1/4 tank.

Post the data her, and we can interpolate for you.

Mine was:
Full = 0 gallons added
3/4 = 5 gallons added
1/2 = 7 gallons added
1/4 = 9 gallons added
1/8 = 12 gallons added.
E = ? Never got that far....


I have the shorter arm on my unit, price I paid to get a 3/8 line. Like mentioned above, stays full for a while, the drops quickly to 1/8 and holds. I have never put 12 gallons in mine, but it is a 16 gallon tank
