Review on OEMTOOLS 24397 2.5 Gallon Manual Fluid Extractor Pump For Oil And Transmissions, With Oversized Handle For Easier Use And Extraction by Chef Buntiloy

It works well, but the assembly instructions are weak. It was difficult to figure out exactly how to attach the suction hose. It looked like it could fit either of 2 ways, but no, it only fits one way. I had to try it both ways to figure that out. It just friction fits (with an O ring seal), but looked like a screw-thingy might hold it. The screw-thingy hold a cap when not using the unit, but it separates into two parts, implying it does more than simply be a cap. I'm guessing the screw-thingy might hold some attachments (possibly a drain spout) that might be included with different model.? I also had a little trouble finding one of the two suction hoses. I was about to return is for missing parts, but then I found it inserted down into a cavity on the top.A nice feature is a suction relief valve, to let you stop after a certain amount of fluid is removed (if not completely draining an item). But, an additional amount of fluid in the hose still gravity-feeds into the container. I need to better judge when to stop (a little earlier), so as not to take out more than I want. Still the suction relief valve is a good feature.It starts to move fluid almost immediately (just a few pumps). You don't need very many pumps in total to accomplish the job. You can see the fluid draining, so you can decide if it is slowing down, and give another pump or two.On an entirely personal note, the purpose I bought it for (and it works well for) turn out not to have solved my problem - in other words, I didn't actually need this tool. But, it is a good tool, and I anticipate being able to use it again, sooner or later. I'm happy to have it.
