Lift pumps and BioDiesel

I have noticed that the factory lift pump on my Ram doesn't like Bio over an extended period of time. When I run B-100 it will only take a couple of weeks to start fluctuating on pressure and eventually quit all together. The odd thing is I can re-install one of the 4 lift pumps that have been in service on it before and that one will work perfectly for a couple weeks to a couple months and then it will act up again. I am not sure what is causing it but a period of rest seems to allow the pump to recover. It might be that the motor windings and brushes being submerged in the fuel have a component that is reacting to the Bio. I have run regular Diesel over the last 5 months and not had any problems with the pump on it now that was beginning to act up at the start of winter. Has anyone else noticed this and if so what pump have you used to replace yours that has an immunity to BoiDiesel, I don't want to go to the trouble of replacing mine with another that will just do the same thing.
