Review on Fuel Rail Pressure Gauge Adapter For GM/Chrysler Schrader Valve Service Port by Sean Spence

Revainrating 5 out of 5

Good alternative to buying a new gauge

It seems for me that the small rubber seal inside the fitting is always the problem with a fuel presser test gauge.I replaced mine with this fitting. It works really well and no leaks. I use it on GM and it's the correct size for that application.

Pros
  • ‎1 ounces
Cons
  • Limited Usefulness: If you only need to check your fuel rail pressure once in a while, this adapter may not be worth the investment, as it may sit unused for long periods of time
