Tried a shim kit, washers were to big. Started it up, thought the fprv was leaking. Pulled it many times. Turned out to be a oring on an injector wasn't on right. Then tried M4 shims and 3 pushed the cap off. 1 didn't. Still leaked after removing the shims and putting them back. Replaces the oring. Still leaking. More tightening. Still leaking. Any ideas?
Start the truck, it's a drip.
Give it throttle, then it'll be a stream, once you let it idle again
