Lumax LX-1341 Multi-Purpose Oil Pump Suitable for precise dispensing of Fluids in tough-to-reach places in Tools, Equipment, Machinery and Vehicles. 1 Qt. (1 L) Capacity Bottle.

Used this to ‘over fill’ a evo 9 transfer case, the factory fill point with this weight of oil will show full well before it fills all areas of the case. That being said it takes a decent amount of pressure to force 90 weight from the bottom, while slow this pump worked well and moves fluid the entire stroke which the cheaper screw on to bottle ones do not, also hold a pretty good suction so fluid in hose doesnt seem to want to flow out if hose is dropped. Only gripe is it had an open hole on the lid to allow air in and as such if you knock it over it will leak. The hose is supposed to act as a plug for storage, i made up a plug for mine instead. Hopefully this lasts

Absolute Junk!!! I purchased this to help replacing the front and read diff fluids. Worked fine on the rear diff but locked up half way through the front diff leaving me in a mess with half the front diff filled and no way to finish it up. Beware, this product is unreliable and will fail when you need it most.

I bought this pump and used it once. It worked fine. Another couple months I wanted to use it again and the pump would not compress. It stopped working. I contacted their product support and never received a response. Bad product, bad customer support, do not buy!

This thing works great when it works . . . .sometimes the check valve that allows pumping gets stuck and then the pump doesn't work. The check valve seems to naturally reset itself. I could likely also tap the straw inside to get it free. So it really reduces the mess when it's pumping correctly, but doesn't always pump correctly.

One thing to keep in mind, the last ounce of product is not accessible because of the level of the pump and the way the bottle is made so if you need to pump 12 oz, you will need to put 13 oz. in the bottle. It was perfect and very manageable to fill my 2015 F150 transmission with fluid during a drain and filter change. I think I had to pump like 220 times for a quart. It seems like a lot but it really wasn't all that bad and it pumps easy. It is graduated on the side and allowed me to keep accurate track on the amount of fluid I was putting in. It also seemed very sturdy considering the cost. I would definitely buy it again.

Ford stupidly removed a traditional dipstick from many transmissions and you need to refill it from under the truck and have very little clearance. This worked perfectly to pump the fluid up and into transmission. Takes a lot of pumps, about 200 for a quart of fluid, but still easy and mostly quick.

I bought this to add gear oil to the transaxle on an old Porsche I have. I read a lot of bad reviews but decided to purchase it anyway because I wouldn’t be using it regularly and it was well priced. I feel that I used it pretty responsibly but by the time I got into the 3rd of 3 quarts of fluid it had stopped pumping liquid. When I removed it from the bottle the pump had fallen apart inside. I’m actually impressed with how bad this item is. Not worth your time. Just find something else.

I bought this for a project, changing the lead frame in my 6r80 Ford transmission. Got this to fill trans fluid back up. Opened it today, (36) days after purchasing and put water in it to try it out and it did not pump. On phone now for hour with Amazon customer service trying to get replacement. Update... Even though I'm passed 30 day return policy Amazon refunded my money and told me not to ship it back. Excellent customer service. I'm changing my 1 star to 3 stars just for that.

Good quality product

works as it should, no complains

It look good I use it for gear oil for my boat

Broke on the second use. Barely ran 3L of fluid total.
