Electric Fuel Pump Light

75" is best, you really dont want to be under 70" or else you will have issues with the coupe wanting to lift a wing when landing/takeoff in crosswinds.
If its below that you might need new "donuts" and if new donuts dont bring it up enough then you can add the spacers from alpha aviation.

What is the recommended height from the ground to the top of the vertical stabilizer . . . is it 75 inches

Yea, I wish there was an adjustment switch, but alas there is none.
I’m beginning to think Vernon is going to be one of my best buddies soon.
Thanks for the help.

Also you might check on your pressure switch, there should be a screw of sorts that you can adjust, and by Loosening or tightening it changes the amount of PSI required to open/close the pressure switch

We got ours from Vernon at Skyport

Lawson,
It looks like I too will be rewiring the fuel pump circuit. It turn out that the pressure switch never relaxes so the light circuit is always open (light out) and to top that off there is no circuit breaker on either the light or the pump.
Where did you purchase the pressure switch?
