If you want to be proactive, replace the regulator as soon as you get it and put the old one away as the spare. That way, you have a brand-new regulator for the trip and you have a known good regulator as a spare.

Carry 1 quart of diesel fuel or your favorite diesel additive. Handy for filling the secondary filter before you install it, eliminates a lot of cranking to purge the air from the fuel lines.
