On the Andair fuel valves that most RVs have, would this turn off the fuel flow completely?
Sounds like in this case, fuel was likely to have been fed from the left tank while the selector was in that condition.
Examination of the fuel selector revealed that the selector was between the left and right fuel tank. Pressurized air was supplied to the fuel selector and it was discovered that when positioned between both tanks, fuel was only supplied from the left tank. The fuel selector was placed in the right tank position and pressurized air was supplied through the lines and the air moved to the right fuel tank line as noted on the selector.
