Appreciation post: The cheap digital pressure gauge from Harbor Freight
I was sure the $35 digital pressure gauge from Harbor Freight would be junk for checking fuel rail pressure. A guy at the shop in Tucson convinced me to try it on a stubborn 6.7 Powerstroke last week. After three tests, its readings matched our shop's $800 Snap-on unit within 2 psi. Now I keep one in my box as a backup. Anyone else find a budget tool that actually works for diagnostics?

But is fuel pressure really that big of a deal?
