I have read several negative posts re: Prime Loc on 24 valve engines so decided to try something different. I eliminated the check valve(2 min job), replaced the small, restrictive fuel lines and 'filter adapter ' and used the larger, 90 degree elbows and lines that came with Max flow kit, and now get 15 # FP at idle, 11 at WOT, and about 12 at 60 mph. It is a rather tight fit, tho, but all works. Only problem is getting the fuel in water plug to work with stock wiring harness!! Anyone had this problem? Numbers are right, I think. My part # is 185200-S, fleetguard #. What do you think? thanks.
