What size (diameter) are the hoses?

The outer thickness of the hose is 13 mm. I have 2 cars, I could insert the pump hose(s) in the pipe going into the transmission oil tank only 1 inch after which the pipe gradually narrowed so I could not use the pump on any of the 2 cars.

Can it be used for potable water?

Biggest issue I see is the grease/oil they use inside it. It feels like vasoline, but they might have used something else that isn't food grade/you wouldn't want in your water. I'd suggest washing it with a dish soap de-greaser, then sanitizing it completely, and lubricate it lightly with a food safe oil (coconut, vegetable oil, etc). Even then you're doing it at your own risk. I would consider this for pumping water that will later be filtered and/or treated and not pumping post-treated/filtered water. For that consider one of those hand pumps for water jugs they use on watercoolers (3/5gal).

Has anyone used this to fill differentials? How did that work out?

After looking at some options I went with some $5 option from a local auto parts store for my differential and transfer case. Worked just fine and saved a few bucks.

Worked perfectly for differential gear oil service.

I bought this pump to do front and rear differential fluid changes on my 2003 Toyota 4Runner. I needed to purchase both a gallon jug and a quart jug of gear oil for this service. The pump fit the quart jug but not the gallon jug. The gear oil is Valvoline 80W90, also purchased from Amazon. I transferred the oil from the gallon jug to the quart jug using a funnel and this method worked fine. The pump worked perfectly. I recommend this pump.

Good product

The product is good, but don’t make my mistake and try to use it with a bottle of bleach. It will corrode the spring and turn your bleach brown.
