Hello Everyone, I would like to test the fuel pressure on the VST system on my 2000 Challenger 2000 with the Merc 240 EFI engine. I see reference material stating to hook up the gauge to the schrader valve which is pretty straight forward, however, the mercury part number for their gauge is outrageous.
Interested in knowing what others are using, the mercury tool looks like it has a hose to it, I appreciate there will be some fuel flowing from the valve, so is the hose there to simply get rid of what could be there. I see people are hooking up the gauge and measuring the pressure but not sure if there is more involved with the hose I see on the mercury one.
Thanks in Advance
