Looking for ways to more easily dispense my Fuel Power into my little Lucas 5 ounce bottles, I turned to the "New" Amsoil Hand Pump. When I received the pump in the mail, I took a quick look at it (specifically at its plastics) to ensure compatibility. I thought, "great, this will work." So, I installed it into my 1 gallon bottle and proceeded to fill my several empty baby lucas bottles. I did work great. I filled several bottles without a drip! This was two weeks ago.
Fast forward two weeks to last night, I went to refill a couple bottles. Pump, pump, pump. Hmmm. No fuel power came out of the spicet, and there was no resistance in the pump. Hmmm. So, I removed the pump from the gallon jug, then disassembled it. Upon a much closer inspection, I realized the pump had a nitrile-type seal, and it had softened and torn away from the pump's plunger/piston.
Lesson Learned: don’t use this pump to pump Fuel Power/Lube Control.
Note to LCD: Finding a compatible hand pump for your gallon jug would be a nice complement to your dispensing options.
