LARRY BRUDZYNSKI Posted December 5, 2008 Share Posted December 5, 2008 /forums/images/%%GRAEMLIN_URL%%/scratchhead.gif Check Valves??? The only thing between the lines and the head are the fittings, unless I'm wrong I thought the check valve was at the Transfer/Lift pump on the frame rail.

STROKER_T Posted December 5, 2008 Author Share Posted December 5, 2008 according to the PCED,the check valves are as at the head,and connects to the fuel supply line on both sides,diagonal from each other...they prevent fuel spikes ...page 4A-50 PCED (7.3L) Quote Link to comment Share on other sites More sharing options...

Bruce Amacker Posted December 5, 2008 Share Posted December 5, 2008 Yea, CRS......... I remember the early check valves that didn't have screens in them, and they quickly released the updated ones with screens to keep the rubber chunkies that broke away from the fuel line sleeves from plugging them. When that fitting plugged or restricted, it was a real MF to diagnose, 'cause most guys didn't want to check fuel pressure at both heads. I also remember a small fitting for smaller trucks and a bigger fitting for F650..... /forums/images/%%GRAEMLIN_URL%%/grin.gif Quote Link to comment Share on other sites More sharing options...
