The Cornwell Fuel Injection Pressure Tester Starter Kit, No. GSI4100, enables testing on most major model vehicle platforms with standard or small Schrader valves. The tester's 3-1/2” gauge has dual-scale dial with ranges from 0-145 psi and 0-7 bar. Its hook-on gauge enables a technician to hang gauge and hose assembly to free his or her hands.
