I am wondering if there are any changes that need to be made to a 6.9 Liter so it will dependable run B50 or higher?

 

All that is necessary is to change the rubber fuel line pieces to synthetic lines, and be prepared to change the fuel filter in the first couple of hundred miles.

Biodiesel is a very good solvent and will clean out the "crud" in your fuel system. Biodiesel will soften up natural rubber, so these short rubber lines must be changed to Viton, or another synthetic.

 

Seeing your from Washington state - in the winter months when very cold like this winter you might want to cut back on the % of bio so it won't jell.

 

Where you finding B50 dude? Or are you thinking about starting to brew your own?

Did you see my post a while back about looking for a partner sto start a small brewing operation?

 

I found a supplier up here in Seattle that sells B99. I mix it to about b50. There is suppose to be a commercial dealer in downtown Kent that sells it also.

I would be interested in a partnership but I am going to be moving soon.
