I got a pressure tester... and it doesn't work. LAME!
I connected it to the schrader valve (gay sprayed out) turned the key to ON (leaving engine off) the pump primed... the tester needle didn't move.
So I repeated this... Needle doesn't move. So I started the car... Needle doesn't move. I press the pressure relief with the car running (should cause gas to shoot out) Nothing. LAME!!!!
