I added the edge this past summer and no problems. My truck fuel pressure has been good 14-15 psi, when idling and the other day it dropped to 3-5 psi for about 5 seconds then went back up to 14-15 psi. Then last night when i was going to work i was going bout 35-40 it was at 12-13 psi then dropped to 3-5 for bout 15 sec. I pulled over shut the truck off. Waited about a minute and started it up fine. Didn't do it again but im still puzzled by this. Any help would be greatly appreciated.
