Solimeta Fuel Injection Pump Pressure Gauge, Automotive Injector Gasoline Tester Tool Kit，0-140PSI/10 Bar

The kit adapters include a T fitting for 70s to late 80's 5/16" and 3/8" cut-to-fit fuel injection hoses that many other kits don't include, which is what I needed for my restored vehicle. There are many other adapters included for newer vehicles that I haven't used but would be difficult to buy individually. The molded case is great for keeping the gauge and adapters together. Many other gauge kits come in cut open packages that leave you storing the gauge and adapters in an unmarked plastic bag that is hard to find when needed.Fuel pressure gauges show not just the running fuel pressure but also how the fuel system holds pressure once the pump is shut off which helped me quickly solve a fuel problem that I'd been guessing at for weeks.

Love the kit. But doesn't work. Tried on multiple cars and for some reason it doesn't show pressure. I tried all fittings and found out that it's the female adapter on the end of the gauge. It doesn't push on the valve on any car. I have pressure and no matter how tight I install it, it doesn't read pressure. After testing it, the threaded fitting on the end of the hose doesn't reach the valve to open the line for pressure testing. Sad to try the product now just to find out I can't return it. I would love a replacement or return this one. I like the quality and want to keep it but it doesn't work. If anyone else can let me know if your set works. Mine only works when I force air into the gauge fitting.

Very few instructions you need to know how to use.

Did not come with small Schrader for most marine engine test fittings ? And most GM automotive….every other adapter in the world that fits ???
