Re: bio-diesel fuel lines... where to find? (pdxcaddy)

Possibly your question should be: Where can I find injection pump seals that will not be degraded by biodiesel over 20% concentration in petroleum diesel. I hear that the magic word is Viton rubber. I'll need some new seals eventually.

good news you will not need new seals for your ip the only thing that
needs to be changed is the return lins form you injectors to the ip replace these with viton and you are good to go
