Well Gang and OP,
As many of you on here have seen and read of my post of the same exact situation. You also saw and read of my remedy to this so that it (retraction of fuel, back into the tank, during a filter change)NEVER HAPPENS AGAIN. And my remedy was, install two, shut off valves in the system. One installed before the ONLY filter I have and, the other shut-off valve, installed on the output side of that same filter.
This way, you can shut both of those lines down, right at the filter, unscrew it, take your time in prepping the new one, and install it. Then, open the valves and, absolutely "0" starting troubles from that point on. It's a cheap and easy fix. Well, I say cheap, meaning about $20.00 plus or minus, depending on where you obtain the parts. But, Brett Wolf and I discussed my situation and, he, CAT, and Freightliner all agreed I had to pressurize the fuel tank and lines, all the way to that filter before mine would start.
I still had to pressurize the line from the filter to the lift pump on the back side of the HEUI pump before it would start. So, with my system, I'll never have to do that again.
