Problems with Bio-Diesel

From contributor E:
"You have to replace fuel line, filters and sometimes pumps because of this solvent nature. Solvent isn't the term I want, but I think corrosive is a bit overboard. It is something else - I just can't think of the term. If you ran petro, then switched over to bio, there are going to be issues because the bio is trying to clean the resides left behind by the petro. You are the first person I know of to have any serious problems by switching."
The above is what I'm seeing around here, too. Numerous guys here are using it, and once the fuel system is cleaned out, no more problems. The filters are catching all the crud and they need to be changed a couple of times.

It was the bio-diesel. I bought some anti-fungal treatment and pured about 10 times what was recommended into the tank. I would let it idle at full throttle for about an hour a day. You could hear it progressively getting better. After day four I was at full RPM and back to operating. Thanks for all the help.

Thanks for posting what corrected the issue.

Some state this dead matter can lead to needing to change the fuel filters as it gets filtered out.
