Sorry, I missed this thread before!
Yes, I am the infamous U-Haul guy, and also the occasional driver of the DirtyMax truck.
As far as electronic fuel pressure gauges, we already make them as part of the Performax system (which requires a control box which works for up to 17 gauges). The standalone version is going to be launched in a few weeks at SEMA. I've been running one in my gasser race car as an oil pressure gauge (I wanted to test the higher pressure ranges and see how it responded compared to a mechanical gauge). It is actually more responsive than the old mechanical gauge in the car! Now that we have production parts available, I'm getting more of them built for my truck (I didn't want to hog all of them when we were scraping parts together for Beta testing).
