I backflushed for more than the recommended time, and now there is a lot of diesel fuel in my veggie tank. What should I do?
Its perfectly ok to have some diesel in the veggie tank. It will burn off in time. The real problem with backflushing too long is potentially overfilling your VO tank This can be messy! If youre having trouble keeping track of backflush time, consider getting a kitchen timer with a preset buzzer, or upgrade to a fuel system computer that monitors switchover and backflush time for you.
