GlowShift 3/8" Quick-Connect EFI Fuel Line Fuel Pressure Sensor Adapter Compatible with Ford Mustang 5.0L 2011+

Worked great to add a sensor to my 6.4 hemi!

With this connecto, on an LS fuel rail, no less. You will need thread sealant (575) for it leaks without some form of dope that is resistant to liquid fuels.

The adapter was used to install a fuel pressure sensor on a non performance pack Mustang GT 2015+. The adapter works well. Just be absolutely sure to use a a thread sealant like Permatex 56521 High Performance Thread Sealant, 50 ml. THIS IS IMPORTANT. THE FUEL PRESSURE IS ABOUT 60 PSI AND WITHOUT A FUEL THREAD SEALANT THAT REQUIRES 72 HOURS TO CURE, A FIRE HAZARD CAN OCCUR AND A LEAK CAN OCCUR AT ANY POINT IN TIME. Plumbing tape sealant is NOT MADE FOR FUEL. BE CAREFUL: YOUR ADAPTER CAN CAUSE A FIRE HAZARD WITHOUT THE CORRECT SEALANT.

Leaks at threads.

needed an adapter for my testing kit to test the fuel pressure on my F150. this worked perfectly.

Little skeptical at First But try the product anyway very happy with it fit right onto my 2011 ram 1500 5.7l Hemi Fuel railAnd allowed me to attach a fuel pressure gauge nice and clean fitment and have no problems so far

I used Permatex Aviation form-a-gasket to seal the threads on the plug and the fuel pressure sensor I was using. 24hr cure time, but I let it cure at room temperature for almost 72 hours. Attached and all seemed well until I goosed the throttle and fuel pressure climbed to around 75psi. Smelled fuel and saw unit dripping onto fuel rail. Removed from vehicle and pressurized. Found leak on port plug side. Port plug was VERY tight and I used a liberal amount of sealant. This unit was installed correctly with proper thread sealant for fuel and still have issues. DANGEROUS. DO NOT USE. You get what you pay for - order from a reputable brand.
