Five star product worth every penny
If you have a turbo, youโre running a catch. Can you really need these check valves itโll save your motor. Install was real easy and you can save me thousands of dollars all metal construction very strong. Very sound part a must have if you have a turbo

Solid well made product
I installed a set of front disc brakes on my 1960 Volvo PV544. Had to install a vacuum booster. Had to install tubing to the intake manifold. The instructions said that in some cases a check valve in the tubing run would improve brake performance. I installed the check valve and now brakes work great. Check valve works. Well made.

Works as intended.
My zero turn would crank a little longer than I thought it should before it would start. I suspected the fuel was siphoning back to the tank after shutdown. This was cheap and easy to install so why not give it a try. Glad I did. Much better now.

Not a strong check valve.
These have a very flimsy rubber diaphragm that will dislodge more than it'll stay in place and cause fuel flow problems because it rolls into the outlet nozzle and blocks fuel flow. Happened on 3 different ones in a 55psi fuel injection system gas line. Toss them. Not robust.
