My brother bought a 2004 Kingpin. It needed the shifter ratchet, so I just got done replacing that and the bike wouldn't keep running after the starter disengaged. Coincidence? I pulled the tank and got the fuel pump out. The regulator was floating in the housing- packings were hard as a rock so have them on order from Mopar per another post suggestion. I made a puller for the access plug out of angle iron if anyone is interested in photos/dimensions. Wish me luck!
