Fuel Injection Pump Injector Pressure Tester Kit 0-140PSI for Car Truck Motorcycle, Schrader Fuel Rail Pressure Gauge Diesel Petrol Engine Diagnostic Tool
LXNEER
Why we love it
Versatile hoses for multiple connections.
Accurate pressure diagnostics for vehicles.
Ideal for fuel system maintenance.
Main Highlights
The set includes various fittings and hoses to connect. 15 inch hose is used for hooking up directly to the 1/4 inch SAE standard Schrader valve on fuel pump, 5-1/2 inch hose for small Schrader valve (compatible with some Ford), and 8 inch hose for M6 fuel pressure test port, and there are also M8/M10/M12/M14 adapters for the corresponding test port on fuel rail. The aluminum tee can splice in-line between the fuel pump and engine for most vehicles.
Designed to test the pressure in the fuel system, help you to diagnose whether there is leakage or fault in the fuel system based on the gauge readings. Perfect for older low-pressure systems with mechanical fuel pumps. One way to keep your high-performance engine in good condition is to invest in a high-performance fuel pressure gauge.
Gauge range: 0-140psi / 0-10 bar. Suitable for most types of petrol / gas / gasoline engines (no more than 140psi). Attention: Bosch, CIS Jetronic, Throttle Body Systems on GM vehicles are excluded. And not for diesel high pressure injection pump or direct-injection engine.
Applies to most vehicles equipped with petrol injection pump (gas engine) but not for high pressure diesel injection pump or direct injection.
