My fuel pressure gauge cost 40 bucks....way cheaper than that unit being sold...besides, what is nice about mine is it is attached via a "T" which allows me to take it off and use it on other vehicles for troubleshooting (did this just last Friday)
Expect to see more of this stuff as machine shops loose work in the semiconductor and aerospace industry.....basicly, I think a few machinest started to look into thier engine compartments trying to decide what they can hog out of aluminum to sell.
hmmmm, what shall I do with my idle CNC sitting in my garage
