Changed mine out the other day. I was on a return trip from Atlanta to Wilmington and the fumes were killing me. Stopped at stealership in Columbia, SC. $26 for two meters of hose
. Will be ordering Viton from McMaster-Carr asap as I'll be running my new 300sd on b100.
Anyway -- my old hoses came off with a slight tug, They were fuel-soaked to the point of being be mushy!
