Review on 🔵 YSTOOL Brake Clutch Fluid Hand Pump Vacuum Bleeder Tool Kit for Auto Car Truck Motorcycle with Power Steering Fluid Bleeding Set, Brake Oil Change, and Hand Pump Jar Adapters (Blue) by Tim Hollins

The case it came in was very good and it appeared to be a well made pump. But as you can see from the picture the o-rings were too big and so it was very difficult to maintain a proper seal. Make a good seal, but still not enough to suck oil through the exhaust valves. I've also tried using it to pump oil out of the master cylinder oil reservoir, but that didn't work. This is my experience, it may be different for others.
