I installed the blue spring upgrade a few days ago. The truck has been and still is running great. However, tonight the fuel pressure regulator is buzzing real loud. I'm thinking maybe a restriction somewhere in the regulator?? Any ideas?

Hey Benny. Yeah it went together great. Thanks for all the help. Its been running good. I just noticed the buzzing today. Sometimes you can hear it with the engine running and the radio off. I'll pull the cover off Saturday. I'm wondering if something fell down into one of the fuel lines while I was working on the truck.
