I recently installed a home generator to provide power during outages (Kawasaki 351cc, 11 hp, single OHV 4-stroke if anyone cares) and searched out this neat siphon pump
, preferring to store fuel in my car than in a tank in the garage. This pump should allow me to refuel the generator when it runs low. Note the neat feature of a squeeze bulb to provide initial vacuum to get the siphon process going. Siphoning does require that the destination is lower than the source.
Anyway, it occurred to me this might be of interest to those who like this sort of thing in their tool kit.
I paid $20.48 for 2, shipping included.
