Both of my Jeeps have limited top clearance for adding differential fluid from a one quart squeeze bottle.

I have an old Sta-Lube (CRC) fluid oil pump that fits on wide mouth Sta-Lube containers and one gallon oil/differential fluid jugs. Rather than transfer new differential fluids to the old one quart Sta-Lube bottle, I'd rather find a bottle pump that fits on a regular squeeze lube bottle. The cap dimensions of a one quart squeeze lube bottle are identical to a regular one quart oil or transmission fluid bottle.

My alternative to my old Sta-Lube jug/bottle pump would be to use an empty gallon or 5 quart oil jug. I'd rather not mix motor oil and differential fluid. I'd also rather not mix residues of differential fluids of different viscosity grades and synthetic/dino. I also have an old suction gun that's messy and very hard to clean. I'd rather keep the suction gun as a little used curiosity piece and heirloom.

I have looked high and low for a replacement lube bottle pump. Any advice will greatly appreciated.
 
Amsoil makes a Lube Pump, check there website or contact Gary Allan or Pablo, I think it goes for about $10.00

Yep, and it's a good one. I've used mine several times now, still works like new.
 
I just use a metal body suction gun I bought from the auto parts store several years back. Works well...
 
Just make sure that you put a zip tie around the hose on the spout of Amsoil pump. I have had it pop off on me.

I think the pumps are pretty universal in size. I would not go near squeeze bottle with a ten foot pole.

A decent auto parts store should have the pumps. If they don't that is pretty lame. Yes those suction pumps really suck in a bad way.
 
I actually find that suction guns (at least the one I use) work really well for gear lubes, it's the ATFs that get messy.
 
Ben99GT,

My suction pump is at least 35 years old, still looks fine, but never worked without spilling all over. I see that they are still commonly available, but I don't have the fortitude to take on the mess any more. I'm glad your suction pump works well because that is the simplest way to go!

My Sta-Lube pump has a two foot long vinyl tube with a gripper pour spout to latch onto the filling hole. The long filler tube can flail around and get a little pesky! Fortunately, there is a place to latch the end of the tube to the pump when you're maneuvering in a tight spot.

I haven't checked for them in years, but I found what you're looking for at Autozone. It looks like the Amsoil pump above, but fits the smaller bottle opening. I originally got it to pump ATF into a leaky manual trans. Most auto stores seem to have a selection of pumps like this.
 
Rhymingmechanic,

Thanks for the suggestion. The Autozone pump (on the internet) looks like the device my well stocked Ace Hardware store sells. The packaging on the Ace pump states that it will pump oil to 20w. ATF, and of course, gasoline, would be fine. It will be worth it to see what they have on display at the Autozone in Waukegan before I begin work. That includes removing the differential covers. Three of the four diff covers have no drain plug...

I suppose that there were more of these DIY tools back in the olden days when I bought my Sta-Lube pump. I suppose it would be best to be less picky. After all my dealer a while back charged me $99 per differential to change the fluids on my Cherokee. Even with a new, less than perfect pump, I would be $$$$ ahead! And the weather is nicer too for working under my cars. That's why BITOG is so successful.
 
I still remember the tall 1 qt gear lube bottles with a tiny spout you cut the end off. What a nightmare, especially with dino gear lube in cold weather........

Seems like I would be lucky to get two thirds of a bottle out.
 
I have owned 2 Jeeps and managed to change the diff fluids without using a pump to refill em. I just keep refilling the squeeze bottle until I get enough in the rear diff.
The 2006 Laredo front diff is the most challenging. I filled it from the engine compartment using a funnel with about 2 ft of hose going into the diff fill hole.

The weather is better now out my way, but the squeeze bottle isn't exactly a squirt gun for getting the lube where is belongs!

The interference of my track bar on the Cherokee begs for some kind of pump arrangement. Even worse for general tight fit in the front of the Liberty.

BTW, you ought to post a picture of your funnel and tube device. You will probably get some genuine applause for the idea!
