Do I need to apply Teflon tape to the Fuel Pressure Sensor threads?Updated 2 hours ago

No. GlowShift Fuel Pressure Sensors come with thread sealant pre-applied to the threads, so additional sealant is not normally required during installation.

If the original thread sealant has been worn off or removed, apply a fuel-rated thread sealant before installing the sensor. Avoid using standard Teflon tape unless it is specifically rated for use with fuel systems.
