Simply change out your fuel lines to fresh new ones. Same as you would if it were an old gas rather than diesel rig, (there's alcohol in gas now too, which is what's in the bio that eats at the old rubber lines. Diesel is not a solvent like gasoline, it lubricates - that's one big reason they are such durable motors.) Modern fuel lines are made to handle this. I've been running B-100 or B-99 in my 300TDT since I got it in '99, (some 150k miles ago.) Other than changing the fuel filters regularly (the bio D cleans out the gunk in your system - the alcohol at work, basically,) that's all I've done. Diesel is diesel. You'll love it! Starts and runs better, emissions through DEQ are better, and it smells WAY better! (And the politics are better...)
And I should emphasize - pack a couple extra filters, both primary and secondary. Whether you switch to the bio or not, but especially if you do. You'll likely see, (depending on the condition of your tank, i.e. has it sat a lot,) the clear little plastic filter fill with gunk after a tank or two of Bio - it's cleaning things out and getting ready to run better! And keep spares handy. I've had to change them at the road side as I wasn't checking it regularly - but that was in the early years when I had to buy Dino diesel as often as the Bio, (just an availability issue.) And I use a Sharpy to put a date on both filters when I change them... It was a daily driver until a few years ago, (hence, the 150k over a few years - and at the time I made a point to change the other, spin on that you can't see into, every six months - just to be on the safe side.)
Good for you! And too bad there aren't more posts here yet about Bio-diesel! (At least that I've come across - but I'm new-ish here.)
The TDT is my third diesel Benz - they are unstoppable!
