Hand Vacuum Pump Pressure Tester Brake Bleeder Kit | One Man Brake Clutch Fluid Bleeder Tool Kit Compatible with Automotive Tuner Tools Adapters

I have used this pump several times on carburetors and other items to test for leakage either by pressure test or vacuum test. Has a selectable collet at the front of the pump to switch pressure or vacuum. Nice kit plastic holder to keep all your different fittings in .. Works very well and would recommend to others needing this tool.*** Issues: the only issue that I have had is the bolt that holds the trigger to the housing - screw some how came unscrewed and fell out.. and the pump was not working until I replaced the new screw to the handle.RECOMMEND: If you purchase this pump I do recommend to remove the screw and Loctite into place to eliminate what happened to me wont happen to you.

Within the same day I ordered it i tested if it would hold pressure using my finger it doesn't it seemed already used the audacity to send me one thats been broken and used is infuriating since now I have to waste time returning it.Leaking

Used to pressure test outboard lower unit gearcase. Works very well. Good quality product. Good price.

I used this to pressure test the lower unit on my outboard motor. Saved me a trip to the “fix it” shop and the cost of having a technician perform the same test.

used this to bleed my trailer brakes that had too much air to bleed traditionally. Switched it over to negative pressure and put the tube over the bleeder valve. I recommend a hose clamp on the tube over the bleeder valve and dripping brake fluid over the whole mess to prevent air leaking in around the tube or around the bleeder threads. Let me get my trailer brakes working quickly, didn't have any issues with it holding pressure or anything.

Its junk dont waste your money used 4 times and now wont hold pressure

This pump works ok but does not hold pressure. I had to put a small ball valve in line to stop bleed back.

works good
