I use two 7.5-gallon Flo Fast containers to bring 91-0ctane fuel from an auto service station to the airport to refuel my Rotax equipped plane.
After about a year the fuel began to leak at the point where the pump shaft emerges and where the crank handle is attached. I ordered replacement gaskets from Flo Fast and installed per instructions. Next use was perfect...not a drop of seepage. Second use was different; major leaks. The pump works fine but fuel comes out of the shaft, runs down the handle and gets thrown away when the handle is turned. Faster its turned, farther the fuel gets thrown. Its bad enough now that it is dangerous.

E-mail to Flo Fast has not resulted in a response as of yet.

Any Flo Fast users out there with suggestions?
