My one day old FPR failed after just 15 minutes of driving. Is it possible that the fuel return line is blocked and the pressure builds up and blows the diaphragm in the reuglator? Just really odd that the FPR keeps failing.
 
I'll answer my own question just so some other guy can find it some day. YES, if the fuel return line is kinked or blocked, the FPR will fail because of the back pressure in the line!
 
Reviving this to say thank you.
Hoping this is my problem, so it can be the last of my problems.
