[biofuel] 1983 Mercedes Conversion...

2004-03-04 Thread crusby2003

x-charset ISO-8859-1I converted my 83' 300 SD to run on Veggie oil, but it's 
not working.  Anyone 
have experience on a similar car and have suggestions?

I tapped in to the heater core loop to heat the oil in a tank in the trunk.  
The oil 
in the back is fairly hot after 15 minutes--not the issue.  I wrapped the two 
5/8 
heating lines with the 1/4 fuel line until they go their separate ways in the 
engine compartment.  The fuel is drawn to the engine compartment through 
an inline filter and then into a fuel soleniod.  The regular dino input is the 
default when the solenoid is not activated and runs no differently than before. 
 
I was able to suck the oil from the tank of cold oil with little trouble until 
it totally 
filled the inline filter and I dared not to suck one more time before I hooked 
it 
to the soleniod.

When I activated the solenoid after it has been running for plenty of time (30 
min.) the car immediately lost power seemingly unaffected by the pedal until it 
almost died about 5 seconds later, but as soon as I switched off the soleniod 
it 
started right back up.   I tried on and off about a dozen times to no advail.  

There is no lift pump on this model, but is there some sort of vacum line that 
assists or is the few inch that I may not have sucked oil through the solenoid 
too much air?  I'm thinking I 'll get an inline heater also just too be sure it 
is hot 
oil before it goes into the injectors.  Any suggestions?

Hello
It has been my experience that diesels will not tolerate air in the fuel 
lines. It would be my first guess that the pump is having trouble 
getting the more viscous oil to itself via a vacuum. I would try getting 
all of the air out of the system first of all, and then worry about 
delivery problems.
