I recently wanted to test the fuel pressure and pump on my Granddaughter's 3.0 v6 Ranger.
I was not happy with all the expensive kits loaded with a gazillion adapters that fit "most" vehicles. Consider that I had just spent nearly $40 on a new compression gauge kit only to find that it didn't work on the Ranger's heads. That meant another trip to town and searching the parts stores for the correct adapter. The 4th store (a NAPA dealer) had one. The babbling idiots at the other three brand name stores couldn't even understand what I needed.
Anyhoo, I didn't want to spend the money for a store kit so I looked around my shop for gauges that might do. I wanted at least 100 psi. Voila, I found it, a leftover cheapo a/c freon installer with a gauge that read up to 300 psi.
Simply cut off the end fitting of the installer that grabs onto the vehicle system. Bleed the pressure off the fuel line Schrader valve and remove the valve core. Using an approriately sized small hose clamp, fit the repurposed freon installer's hose over the Schrader and clamp it down. The trigger on the installer even allows the fuel pressure to be bled off into a container when the testing is over.http://www.ranger-forums.com/rf/images/icons/icon3.gif
