This is what you want, a cheap, rotary, fuel transfer pump.

I borrowed a pneumatic piston diaphragm pump to remove 280 gallons prior to cleaning our 5 tanks X 380 gallons total capacity. Diesel is not volatile so only common sense is needed to handle it. No big deal. If you plan to re-use it, put it any convenient clean container such as 5-gallon buckets.
