[QUOTE="PSDJunky, post: 1550801, member: 31422"] Idk for sure about the DEF. But, I'd expect it to be crystallized, especially in the lines. You could see if you could blow through em... maybe... if you've ever done that with a sealed gasser fuel filter, same principle. Surely there's something you could use with compressed air to clean em out, like carb n choke cleaner [emoji848] brake cleaner, sensor cleaner...something that will evaporate. [emoji2371] I'd hope ya wouldn't have to replace em. Your tank probably needs some TLC or replaced as well. Then, there's the DEF injector(s?) to contend with too. Nah, you can wipe of the dielectric grease, no sweat. However, I'd check them to make sure they're not corroded, especially after 6 yrs, & get them cleaned or replaced first. Once they all look good, I'd put fresh grease on em before connecting all the connectors. I put that chit on all my connectors that are exposed to the elements. [emoji1688] [/QUOTE]
