Better yet, why not use the Ford electric vacuum pump of the `99 diesels? They weight about 12 ounces and barely larger than my fist. At 200 bucks they are a lot cheaper and lighter than an aircraft pump. And I put 280K on my truck before the pump went out last winter. It ran the 4x4, the heater controls and some of the turbo controls. I would think it could run a pair of gauges??

They were used on the Chevy pickups with the 6.2 litter diesel engines. I put well over a 100K miles on one with no problems. They could be belt driven or a coupler could be easily made to drive them direct. Just a thought.
