I found a place a couple yrs ago that has all kinds of fuel hoses when I was at work and have it saved on my work computer...I had to have a hose I couldnt find anywhere for my C30 when I built the bed for it..they had what I needed.. I "think" the site above is it... I'll verify tonite when I'm at work..
