I have a very similar one to that which I used previously. The container fills up quickly though. And since it's pulling on the common return line, the diesel (and/or air) could be from the injectors or the HP pump, if I understand correctly. That being said, when I was priming with the diesel purge, it didn't take much effort from the vacuum pump to get the diesel purge introduced into the inline filter.

I can't disagree. Especially considering that the (potential) fault only happens when the FPR seemingly gets warm. Lower current, higher resistance?
