Until now, testing a fuel system was a 2-person job.  The Stant 12265 Fuel System Tester makes it a one-person job.  And you don't even need to start the engine. 

Designed especially for fuel systems utilizing threaded caps, the 12265 has built-in devices to avoid system damage and is easy and effective to use.  Simply thread the special cap of the 12265 in the filler neck of the fuel tank, tighten the cap and pressurize to a maximum of 50 inches of pressure as indicated on the built-in gauge.  Within two minutes, you know if the system is leak free.

The Stant 12265 comes with instructions in its own attractive carrying case.
