I recently had to drain my 15 gallon wing tank through a 1/8 NPT drain valve that had to be held open. If done by hand the fuel would have run up my arm, so I held a short length of rubber tubing in a wrench and levered it over the edge of a funnel into 2-1/2 gal. fuel can. This worked, but it took 3 hours of holding the wrench to drain the tank. The Saf-Air 1250 will solve this problem in the future, as it can be locked open. The products (2) arrived quickly, intact, and will be installed soon.
