Hey all,

Well i installed my elec. fuel psi gauge and it doesn't work, i checked the gauge and it's getting power and its grounded right and the light wires are connected but the lights don't come on. So pretty much i'm SOL because i can't think of what could be wrong.

What pressure range is the gauge?

what does it start at and where did you hook it to

I'm suspicious of ground if your lights and the gauge don't work, but you have power to the unit

If your lift pump is only making 3 or 4 psi (which is in spec) you are not going to be able to see that on a 40 psi electric gauge.

no this is with the airdog II 165 which should at about 15 psi it is connected to the cigarette lighter. My guess would be its the ground right now.
