Re: [Biofuel] Neophyte seeks advice on runing 1983 Mercedes 300SD on BD

Hello Thomas.
Congratulations to a good car choice.
You may have filter clogging problems in the beginning of BD use.
Therefore I recommend you to move the feed pump strainer (it is a strainer,
not a filter) upwards so it can be easily reached from above for swift and
simple exchange. this is done by longer rubber tubes.
This will simplify the filter/strainer replacements.
Good luck to you !

Subject: [Biofuel] Neophyte seeks advice on runing 1983 Mercedes 300SD on BD


 Hello. I am an aspiring biodieseler with an elementary background in
 chemistry. I would like to run my 1983 Mercedes 300SD on biodiesel. Can
 anyone recomend a good formulation to use? Should I make any
 modifications to the vehicle before I attempt to change over to BD? Any
 advice would be appreciated.

[Biofuel] Neophyte seeks advice on runing 1983 Mercedes 300SD on BD

Hello. I am an aspiring biodieseler with an elementary background in
chemistry.


:-) Some/many of us don't have any chemistry at all.


I would like to run my 1983 Mercedes 300SD on biodiesel. Can
anyone recomend a good formulation to use?


If you're buying it, B100. If you're planning to make it, start here:
Where do I start?

... and follow the learning curve.

The common advice to change the rubber parts in the fuel system to 
Viton or whatever's resistant is overstressed, IMO. The disaster 
seldom happens, and even if it does it won't be sudden, you'll have 
time to take action.


Some folks have had trouble with old Mercs and other cars having lots 
of gunk in the tank, which biodiesel loosens up, or rust, if it's 
been standing for awhile, and biodiesel loosens that too. There's a 
particulate filter *inside* the tank which gets blocked, and you 
can't easily get at it. The solution has been to take the filter out 
and refit it or another one outside the tank where you can get at it 
to clean it or change elements until the gunk's all gone. Again, wait 
till it happens, but be forewarned. It's a good idea to fit a 
secondary cheapo filter upstream of the main filter anyway. Apart 
from that, no mods necessary. Lots of folks here have old Mercs, I 
once had a much older Merc (1959), but I'm sure they can give you any 
more specific advice. They all seem to love their Mercs, and the 
Mercs seem to love their biodiesel.


Best wishes

Keith
