HX Mod Question
I ordered the HX Mod from Diesel Innovations early this week for my "new" 97 F350 PSD CC 4x4. It arrived day-before-yesterday (great service!). Unfortunately, I ordered it without looking at the engine. When I went out this evening to survey the install, I found that the #5 port has a line that runs from the high pressure pump outlet block. I believe the normal connection point for this line is the #3 port, which on my truck is plugged. Since the HX Mod is supposed to connect between the #5 and #6 ports, I'm kinda stumped. I'm wondering whether this may have been done to serve the same purpose as the HX Mod? I'd appreciate any advice....
Thanks,
Keith
