Inclined to Tank You

One end of a fuel tank stand has settled causing the tank to be sloped at 10°00’ from back to front. This prevents some fuel from draining out of the bung at the bottom of the tank’s front.tank1

The tank is cylindrical with a 48” diameter and 72” length (inside dimensions). The bung is 2-1/2” diameter and its opening is located 1” above the inside tank bottom.

How much fuel, to nearest 0.01 gallon, is left in the tank? Assume 10% ethanol fuel with 89 octane rating (R+M method), tank wall roughness is 0.00015 ft, and meniscus effect is negligible.
