Hand Pump

Question for all,

If you use a hand pump to fill differentals and transfer case,
what do you clean the hand pump with after use?
Would not want to contaminate anything when I use it for the next time!

I would just let it drain out really.

Maybe some paint thinner to clean it and let it dry out completely.

Use brake clean. Thinner or mineral spirits will kill the plastic...

I usually don't worry about it. Before I pump any fluid in, I always have to pump the old fluid out. Pumping the old out first removes any different kind of fluid that may be remaining inside the pump.

I Have a small tank The name is "sure shot" it is a pressurized Tank holds about two quarts @ 60 psi work like a charm. you can find them at lowes
