I've read of people replacing the cigar hose with a longer section of normal fuel hose. Their thinking was that the longer section created extra volume and would serve the same purpose as the cigar hose. Most, if not all, reported success.

Can anyone reference a picture of what this cigar hose looks like? I'd like to make sure someone didn't lazily replace my return hose from the filter housing with regular hose.

It starts skinny, baloons out, and goes back skinny. Like a big cigar the bad guys have in the movies

I replaced the cigar hose soon after I got my 85 300D with regular hose, since it sure looked "swollen". Ran that way for a few years until I read here that it was supposed to look like that so bought the correct hose. The engine did later fail, but I doubt anything to do with that since I noticed no extra vibrations or such either way. I don't know the exact timeline.

Yea, mine definitely doesn't have that. It's an 83', it's only 11.50 on Pelican. You guys think it's worth changing back?
