I was looking at Genosgarage.com. It is $75. I want to know if it is electrical or mechanical. I also want to know if everything is included with purchase of the gauge.

Thanx.

 

I have one. It comes with everything you need including the sender. I got the billet fuel filter cap that the sender connects to also. Made for a pretty easy install. Their FP guage is a decent guage but I sometimes have to tap on it to make it work and it also sometimes shows low pressure until the cab of the truck warms up. Their instructions really suck too.
If it were me, I'd get a different guage. I will probably get some different guages in the future due to this and the fact that they do not match the stock guages very well. The white face guages match in the day but not at night. The black face guages match at night but not during the day....
They are the cheapest guages out there and that's why I got them. I'm kind of a tightwad.....
