Bill Reference: Using a fuel pump to remove crankcase oils; I would not use an automotive type fuel pump as a used oil transfer pump. I am assuming you were referring to a standard electric fuel pump as used on cars and trucks. The valves in these pumps are not up to handling grit and other particles suspended in the pumped fluid. Another reason is that some of these electric fuel pumps have the motor right in the pumped fluid, probably for cooling and so there is no requirement for shaft seals that could leak. Anything made expressly for handling flammable liquids is going to be far more expensive than run of the mill pumps. On the other hand, lubricating oils are not low flash point liquids and so there is little fire danger from using a non-rated pump for this service. For insurance and other purposes though, I wouldn't recommend using a pump not rated for flammable liquids to pump lubricating oils. I used a small rubber vane electric driven pump for a number of years to drain the crankcase oil until the motor finally gave up. It gave up because I was running a 6 volt motor on 12 volts and it just didn't like it all that much. Yes I knew it was a 6 volt motor, but I had to try it anyway to see if it would work, and it did, sort of, for a few years anyway. This pump was similar to any of the small recirculating pumps of that type which have a neoprene impeller. If it had a 12 volt motor, I would probably still be using it today. I bought a small plastic hand pump specifically designed, and sold to drain the crankcase oil and it worked, except for the lack of a decent seal where the piston rod to the handle comes out of the top of the pump. the one time I used it to change the oil, It leaked the black stuff all over the place out of the top and that one too will go into the scrap heap. A pump of this type should have a metal piston rod that can be more easily sealed than a cheap plastic rod or tube. Russ Hughes Slo-N-Easy Richland, Wa.
