Fuel Pressure Relief Tubing Brass Nut that connects the return line to the FPR housing cap.

Fuel Pressure Relief Tubing Nut
If you have ever broken the threads off the factory FPR housing, you know how difficult it is to get the broken piece out of this brass nut. It is very easy to damage the brass nut in the process.
This replacement nut made by Parker is the OEM original nut. If you have had to cut the flare from the 5/16" return line to remove the broken housing threads, you may need this nut before re-flaring the stainless hard line.
Order of 1 = 1 nut
