CFM-Tech Fuel Psi Guage Adapter For GM Tbi 2.8/4.3/5.0/5.7/7.4

No more removing your fuel filter - no more climbing underneath your vehicle - no more hassle - when checking your GM tbi fuel pressure!!!

We've asked several gauge manufacturers for years to make an easier way to check fuel psi for the GM tbi engines. They would not do it so , again, we spent the time and $ to do it ourselves.

Our adapter installs directly into the throttle body replacing the OE fuel line to tbi adapter.

It also features 2 x 1/8" NPT ports ( 1 plug included) so that a mechanical and/or an electrical guage can be utilized.

You wanted it - we wanted it. Now we all can have it!

Guage sold sperately.

Note #1: Permatex #2 or equivalent thread sealing compund required (not supplied) for port plug and fuel psi gauge fitting required.

Note #2 - Adapter comes with new gasket on male end where it attaches to the injector pod. Use of thread sealing compound is not recommended in this location.
