Besides checking the valve for function, its a good idea to occasionally check the entire system. Disconnect the hose at the intake & put a vacuum on it. The vac-hose sections at the front & back of the under-car hard line tend to crack from oil inside, usually in an area where they can't be seen. Occasionally you'll find a Pantera where someone has substituted cheaper fuel hose for nice stiff vac hose, and the more flexible fuel hose collapses under vacuum.
