New to the forum, so hello, and thank you all in advance for any help yall can provdie.

1st item, have a 1973-220D engine (615.912), that we put onto our mulcher, and we have been having a heck of a time finding some parts. Specifically an Oil Pressure Sending Unit, and a Fan (not the fan clutch), just the fan itself. Any suggestions on where such items can be found. Most parts places just laugh when we call, or want to sell us a complete fan assembly, with fan & clutch, etc. Been trying junk yards, but that is like trying to find a neddle in a hay stack.

2nd item, read where others had sent their cards/computers into SpeedTuning, so I did that on my 1999 E300TD. WOW is all I can say, worth every penny. Fuel milage went all to hell, but who cares, thing runs fast as sheet. Thanks for whoever found that place.

3rd item, been runing my 1999 E300TD on every blend of Biodiesel imaginable, and can not seem to find one blend that works better than the others. But the car definatly love bio.

Any help on the parts would be great. Thanks in advance.
