Review on WENBIAO 0 140PSI Injector Injection Pressure by Josh Whitehead

While the gauge works and is fairly accurate, the adjustment range is a different story. I've used it on 10 different cars in the last week and for some reason the threads on the adapters match the gauge but not the fuel line fittings. I had to use rubber hose connectors on 8 out of 10 vehicles tested because the fittings did not match the vehicles. Otherwise there are no fittings for a standard Ford Schrader valve. However, it has diagnosed every car I've tested, faulty fuel pressure regulators, clogged fuel filters, faulty fuel pumps, etc. So for the price it's a good investment, it just takes a little longer to build a leak-free plug adapter to the fuel system.
