I've been having a problem with a hard start lately on my truck. Its a 370hp n14 in a 96 Freightliner FLD. Sometimes it will fire right up but sometimes it has to crank a little bit to get started. Was wondering where the check valve was on this truck. I took the line off the front side of the ecm where it comes out of the block. There was a 90 degree fitting coming out of it but nothing inside it. Is there suppose to be one there or is it somewheres else? I just switched my filter head over from the upside down filter with the clear canister to a baldwin filter head running a 1259 baldwin filter. Any info is appreciated.
