General purpose pumps
P32 is on the right track here, I too have one of these pumps, it could actually suck the chrome off a winch if necessary. The fact that it is manually operated makes it an ideal choice minimizing moving parts to replace. Most importantly, you should not use a electric pump for removing liquids with low flash points, can you say BOOM (as in explosion) not the thing you hit your head with during accidental jibes?
Discounts are nice but you can''t collect them if you''re in the morgue!
