How cold does it get at night? What fuel are you using? Winter blend? Biodiesel?

If it doesn't fit, FORCE it.
If it breaks, well, it needed replacing anyway.

I think you have some fuel pressure or HPOP issues. You should inspect the rubber check ball above the 'rock catcher' for cracks. I've replaced a bunch of those.

Do you have any diagnostic software?

If not, it might be best to get someone who knows what they're doing to look at it.
