Tioga Won't Budge after long neglect. Help, please.

How's the project coming along? I've been following your thread.Anyway... My E450 has been sitting since last fall so I thought i'd get it running and check things out.Guess what.Crank no start,fuel pump.My setup looks exactly like yours.One question...Was the filler and vent hose covered with some ungodly black stuff that you managed to get all over yourself and everything else you came in contact with,like carbon black?Did you find a source for that hose? Thanks!
