Elsbett Single Tank Conversion

I am wanting to convert my 82 mercedes 300D to run off of WVO. My daily commute is only about 14 miles round trip, so I'm trying to find a way to convert it that won't require a lot of heat up and purge time. I ran into a website with advertising the Elsbett single tank conversions, which seem to be about perfect for what I want...I little too much so, actually.

Is anyone running one of these conversions? How does it work for you? Does it really make it possible to run most of the year on straight WVO? Have you had to add additional heating elements? Thanks so much for any input you can give!

Hi Ariane,

I was an Elsbett dealer. I did a couple similar conversions to your '82 M-B. It does work well.
You'd have to thin the wvo down to 60% wvo/40 diesel in the winter. But you should be able to run 80 - 90% wvo most of the year in Georgia.
Here is some info on an Elsbett single tank conversion I did:

Elsbett has gone out of business, but Alexander Noack continues to sell parts and may be able to sell you a whole kit. go to www.greaseenergy.com Or email Alexander directly at: noack _at_ anc _dot_ me

Of the two conversions I did, neither had a problem with the kit. Both had problems finding an M-B mechanic. The cars run great, until they need help and then it's hard to find parts.

Before you do anything, make sure you can find someone willing to install the kit.
The fuel plumbing is simple enough, but the glow plug wiring involves cutting into the existing glow plug wiring. And you need to find a BOSCH diesel injection place to rebuild the injectors.

My HOW-TO for my VW TDI details the installation. It's nearly identical for the M-B, but for the g.p. wiring.

Adding a tank ( engine block) heater ( see bottom picture ) aids starting when it's < 50*F out.
It's not necessary, you can just ad more diesel to thin. I doubt you'd get much use for it in Georgia.
There is no heat supplied to the tank. This helps prevent polymerization of the wvo in the tank.
And not needed for you anyway in Georgia.

It's a simple reliable system.
Only problem I have had is plugging fuel filters from algae.
And fixing dirty or loose wiring.



You can email me for help.

Update:
I hit 200K total bd and WVO/SVO miles!!
180K on WVO/SVO blend, 50-90%.
http://ctbiodzl.freeshell.org/votdi.html

The kit: original but for inoperative fuel filter heater. wiring went bad, only miss it in winter.
See my drivers log for a complete detailed documentation of my experiences.

The car: only fuel related problems were a 3rd injector w needle lift sensor that went bad at ~240K miles. And there is something weak in the fuel quantity adjuster, I get a CEL on cold start-up. If the fuel is really thick it might go into limp mode. Other than that it runs great, like new.

Overall: replaced cam followers at 180K total after a cyl head repair. 4 were slightly worn.
gets ~3K miles per quart of crankcase oil. Starts on first try in < 1 sec, as long as fuel not too thick. If too thick needs help with ether squirt or tablespoon of gasoline in the intake and some hand pumping of the ball pump. The cyl head intake was cleaned when the cyl head was out for repairs. The EGR valve has never been cleaned except hand wiping with a rag on the inside. The inter cooler has never been cleaned. All other equipment is original including the fuel injection pump, and 3 of 4 injectors.

Still can get 45 mpg on veggie blend.
Hard to keep track but saved ~$15K so far, relative to my old Stratus gasser or a bd fueled TDI.

Tips: getting 20K miles per fuel filter now that I double cold filter @ 1um, and use a biocide from Stanadyne. 1 gallon jug is $80 but lasts years.

Update: Hit 300K miles total last week in my '98 VW TDI. About 220K on WVO/SVO with the single tank Elsbett. Starts instantly in winter, burns only one quart of crankcase oil in 5,000 miles.
Fuel related problems have only been blockages due to algae or bacteria.
