Recommendations for Gear Oil Transfer Pump for Transfer Case and Differentials? (1 Viewer)

^^ the pump above fails often. I am on my 3rd, sometimes it wont pump. I think the best is the 1 gallon pressure bottle as stated above. I can see the cleanliness of using it even without using it. Does HF gallon pump do the job? I bought a gallon for my dad and he said the O-ring failed within 2 months of use.

This is what I saw. Mostly complaints about those failing. Also, with the pressure sprayer, you're only trying to pump air. With the hand pump, you're trying to pump the gear oil, which is harder.
