I'm swapping my 6.9 to a 1992 7.3. Just a few changes, nothing major. Oil cooler,engine mounts, few brackets,etc. My question is on this '92 engine [ out of an E350 ambulance ] at the injector end of #3 fuel line there is what may be a regulator of some sort. The 6.9 does not have one and I don't believe my '88 7.3 had one either. Do I need this thing? I took it off and used the 6.9 fuel line. Should I put this little gadget back on or leave it with the 6.9 fuel line? Just not sure what it is.
