Here is a possibility in a cheap pump that uses garden hose fittings that will allow you to pump up to a larger size container like a 5 gallon. You could use it at the bottom with a piece of 1/2 inch garden hose slipped over 1/2 copper tubing, or even at the exit end of a siphon. I would think it would work with oil too and last for your job.franco b wrote:A siphon also has to be lower than the bottom of tank and any hose in the tank will tend to bend and float on top of the oil.NJJoe wrote:Probably cant drain it all in one shot. I envision my coworker making multiple trips to my house to refill all sorts of containers until all 50 gallons are out. Would the top pipes be better in this scenario? I don't think I see a valve on the bottom boiler feed pipe. I think once I cut that, the oil will continue to pour out.

Be sure to remove the old fill and vent on the outside when done. It has happened that oil companies have tried to fill by mistake.

I would go this way ... using this type of pump .... I would buy 2 in case 1 craps out on ya. 50 gallons is about 400 lbs.-to heavy to move in the tank w/o killing yourself. Looks like a cheap peristaltic pump.
