Cigar hose and biodiesel...to change or not to change?
I am going to put vitons hoses in my 300TD because I use biodiesel. I have seen lots of discussion about what the cigar hose does, and wether it is necessary or not. What have you other biodiesel geeks done, and have you have noticed any difference if you put a normal hose in place of the cigar hose. I have a viton to replace the cigar hose, but it is just a normal shapped one.

Do a search on "cigar hose" - it performs a purpose to reduce fuel "hammering" or some such thing and most likely it is best not to just eliminate it. Get a new one from the dealer, it will hold up to BD for a couple years at least.

Are you having problems with the bio eating your lines? Neither one of my cars had this problem. However, the original Datsun beater truck we tried it out on goes through a set of hoses a month. I think its because there's a lot more rubber hose exposed to the heat of the engine on that truck as opposed to the Benz.

I replaced the cigar hose on my SD when I got it on the road in Oct. I didn't want to spend $10 on a new hose and had regular fuel line in stock to replace it.
I havn't noticed a difference.

I would guess the MB engineers did not just put that funny looking hose there just to get us to ask questions. They obviously thought it necessary and it would have been cheaper to use a regular hose. The hose is not that expensive so just use it.
