Ive changed all my hoses to VITON but wasnt able to source a replacement banjo return hose. What is everybody doing for that?
Will a simple straight hose do any damage? Im sure Fritz put that banjo hose there for a reason.

The "cigar" hose? Just use the stock piece. It will hold up to B100 for years if it is in good shape.

I think he is asking about the clear (well, it's supposed to be clear. it was when it was new... just not any more...) hose that goes from the primer pump to the IP and the secondary filter. I would get some new hose from the dealer for that.

Wow, I had no idea that hose was supposed to be clear!

I have had no problems with the semi-clear banjo bolt hoses or with the cigar hose for 2 years on B100 biodiesel.
