Buy a garden sprayer with a hose and plastic wand. Cut the wand to your desired length, then heat and bend the wand as you'd prefer. I do a looping 90 degree angle towards the end so as to reach differentials in vehicles. You could do a bit more than 90 so you could hang it from the fill port while filling. Pump the garden sprayer until pressurized and squeeze the trigger. Way easier and faster than dealing with those pumps.
Basically you're making a poor man's version of this--

Made these two up out of a couple $10 sprayers a couple years ago and they've been great so far. One I use just for Toyota WS ATF and the other for Valvoline SynPower 75-W90.
The same 1 gallon spray bottles now sell for north of $15. At the time I was trying to copy the Motive oil pump which go for $90 or so. There are other companies selling similar on Amazon for $50-$60 now.

Posted these in the 'show us your new tools' thread earlier but figure they fit here just as well. I turned a couple $10 one gal sprayers, 1/4ID tubing, and a couple 3/8 PEX ball valves into a couple oil transfer pumps, one to be dedicated for transmission fluid and the other for gear oil. I also bent some stainless pipe I had scavenged from something at some point and a couple end caps from an assortment for ends that should let me hang the business end in a fill plug instead of me having to hold the hose in place while I pump 12 qts or more in a transmission. The Motive and other pumps like it that I was copycatting do tend to also have a pressure gauge which I contemplated adding too but didn't really see the point or benefit for the added cost. Those commercially available versions tend to sell for $80 and up each. I was able to make both of these for less than half that.

I bought a pump like shown in the OP post. I was changing all the fluids in my Dodge 4WD. Transfer took ATF, diffs were 90 weight. Trouble I had was the pickup pipes kept falling off down in the bottle. Put a longer hose on to hot the bottom of one bottle doesn't work on a different bottle. I guess it was better than using a squeeze bottle that you have to keep filling up.

If it's just gear oil for a diff or whatnot these squeeze bags are wonderful. No pump needed. I have to believe whoever came up with them definitely had actually worked on cars/trucks before.
The only drawbacks I've found for the squeeze bags are 1) it's hard to get the last couple of ounces out; and 2) if you try to refill them from a gallon jug it's easy to make a mess.
But they are way faster and easier than a pump for many applications.Beerhippie

3) Try to set one down with the spout cap off. Clean-up on aisle three!The only drawbacks I've found for the squeeze bags are 1) it's hard to get the last couple of ounces out; and 2) if you try to refill them from a gallon jug it's easy to make a mess.

I've been using one similar to the one originally posted for decades. I do at least 2 outboards every year.
It has a metal fitting and soft flexible clear rubber hose.
I do recall having a couple that the pump failed quickly, they had a plastic fitting and stiffer translucent hose.

Shop I used to work at had a former fire extinguisher -- one intended to spray water using a charge of air. Same idea as a garden sprayer, just another alternative should you happen to have a spare air powered extinguisher handy (they're pretty pricey new, a Motive pump is cheaper). Ours was a reject from a fire department, removed from a truck because of a leak; didn't matter to us it wouldn't hold air for a week.

I just use some tygon tubing and hold the end up above the diff snaking it through the wheel well. Put a funnel in the end and pour away. Best to have a helper and my lovely wife does a great job! If I am using gear oil from Ravenol, they have a nifty flexible spout built in the bottle which helps a lot.
As opposed to a fantasy $400 Fluke multimeter that only a handful of people would buy per year, this is something I don't understand why it isn't available- a $10-20 drill driven pump that screws onto the standard quart jug. Add your own fill hose. Even if it was $20 and only lasted for 20+ quarts, I'd still buy one as it'd last me ~10 years as a DIYer.

I use an older one, similar to what OP posted. Likely close to 20yrs old now.
No issues with it, I did rig it with some longer tubing so I can have the pump on the ground and still get fluid in. Have used it on a vertical plane, basically pressing it against frame/suspension to get it to pump one handed.
Will employ the idea of modded pressure sprayer for a back up unit.

If you don't care about cleanup, or just want to use it strictly for gear oil, the motive or garden sprayer works awesome. I added a 1/4 turn ball valve but I still manage to make a mess. You can fill up a diff in just a matter of seconds with that thing pumped up to 30 psi.
Something odd I noticed, if you leave the gear oil in the jug a long time, something separates out of the oil. I guess its some of the additives...
Its not fun if you trying to clean the pump if you want to use it for different fluids. The only two things Ive ever used it for is tcase fluid and diff oil. I dont recommend using it for brake fluid.

Mobil1 doesn’t come in bags.If it's just gear oil for a diff or whatnot these squeeze bags are wonderful. No pump needed. I have to believe whoever came up with them definitely had actually worked on cars/trucks before.
Same. I greatly prefer this basic style pump for marine lower units. The only issues I've had are with crappy easily replaceable or re-clampable hoses. The one I've been using the past several years is flawless, was cheap.

Yeah, I just changed the oil in both diffs and the transfer case in my truck, and was shocked when I saw $18-19 a quart for full synthetic, even more for the fancy brands. In the end I found some gallon jugs and a 20% coupon; that eased the sting a little. But still.
I've been using the Super Tech full synthetic gear oil at Walmart; it's ~$10 /qt where I live. Valvoline is at least $5 more a quart, Mobil 1 is typically even more expensive, so I've given up. I do still use Mobil 1 in engines.

Back in the day I used an enema bucket. No mess as long as you can catch any overflow.
The only drawback was it took hours. I just let the manual transmission fill overnight.
