Well, my GVR 4 is nearly ready to fire.
Oil primed, etc.
Drained tank, filled with 5 gal premium.
Figured I would try firing on old gas in line: nope.
I disconnected the AN fitting at fuel rail and it is dry.
I cranked a few times and nothing.
I will swap the fuel filter but wanted to make sure the pump is actually running first?
Can someone explain which is the test plug or post a pic, please?
