  • Great parts

    I couldn’t find this part any where it was very easy to find it on glow shift’s web page.

  • Perfect fitment

    Only gripe are the directions...even though it's a no brainer. The main instruction book shows to use the lower port, but the instructions with the adapter shows the upper port. I used the upper port, but after priming the fuel bowl, I had to crack the cap to bleed out a minimal amount of air because the gauge was slammed at 100 psi. After bleeding air, gauge is reading 85-90. Remove the spring loaded crap in the filter stem, and throw a bb in the regulator with a new filter while you're at it.

  • Good customer service

    I am using it as an adapter to add to my fuel injection pressure test kit for Ford 7.3. it works well and had paid for itself. I have already used to isolate issues on two trucks this week.

  • Needed if you have a 7.3 Powerstroke

    Easy to install. Needed if you have a 7.3. If I were to install it again, I would install the adapter, then the pressure sending unit. I installed mine post-filter so I can tell when my filter needs replacing.
