PLEASE NOTE: We no longer have time to assemble these conversion kits so we are discontinuing them. The cost of the individual components has also gone up drastically. We have ONLY ONE LEFT. It is assembled and has been in a car that has driven less than 1000 miles on a new conversion. All the hard work is done and it is ready bolt into your older Mercedes diesel with all the hoses and clamps you will need. It will bolt directly into a W123 chassis without modification and into a W116 or W126 300SD with only slight modification to the brackets.
It will come with a new FM 100 filter element installed and an extra spare filter. You will receive all the instructions that normally come with out builders kit but you can disregard all the pages relating to putting it all together. This could save you 6 to 10 hours of work. All the following information you can read that did pertain to the kit. Not all with apply. This was assembled personally by Kent. When it sells no more will be produced. PLEASE ALLOW A COUPLE EXTRA DAYS for unit removal from the car before it can be shipped.
The STC 100 builders kit is the heart and soul of all our vegetable based fuel conversions. Its key VFM (Veg Fuel Manager) component is central to every kit we offer. You will need to read all the text that follows to fully understand what this kit will do, what it takes to install it, and how you can modify / upgrade it to operate more efficiently in cold weather. This is not like anything your average SVO conversion company sells. It is easy to build and to install, but reading is a prime requirement for understanding how it can work for you in your climate.
- STC 100 stands for basic Single Tank Conversion: This means you can operate with the factory tank to hold your vegetable oil fuel. No second tank is required. 100 is our entry level kit. To learn more what this all means see below:
- VFM designates the component module that properly filters, heats and routes the SVO fuel. This single compact module does it all and is easy to service, maintain and repair.
- SVO WVO designates Straight Vegetable Oil (new oil) or Waste Vegetable Oil (collected from restaurants).
- Builders Kit means you will have to build some of the major components of this kit before you install them in your diesel. This includes assembly the heat chamber, finding material and building brackets to fit your model, mounting filter and boost heater to bracket, and completing the necessary wire and plumbing modifications. There may be some clamps and small hardware you will have to purchase on your own. This will save you money as well as allow you to modify the kit to fit in many different models of Mercedes up to 1993.
The STC 100 modular component system is well suited for running SVO (Straight Vegetable Oil) in warmer climates or when you do not want to add the second fuel tank. This easy to install kit will convert your Mercedes diesel to run efficiently on WVO (Waste Vegetable Oil) in locations where the temperature seldom gets below 40 degrees F without modifying the fuel or your driving habits. When it gets cold or when you run out of WVO you can mix in diesel in any ration directly into the tank to thin the oil. At any time you can run on straight diesel or biodiesel without trouble. All you have to do is turn off the electric fuel heater at the VFM and reroute your return fuel by changing the position of the fuel return valve.
You can even use this kit if you are using only biodiesel. When running on B100 in colder climates you can change the routing on the fuel hoses to heat the biodiesel BEFORE it goes into the FM100 5 micron filter. This will increase horsepower and extend filter life by eliminating waxing in the filter element.
Our unique VFM (Veg Fuel Manager) uses an electric heat boost chamber to get the oil temp up to over 150 degrees in under 2 minutes allowing for smoother starts and quicker acceleration when cold. This initial volume of hot oil literally purges the cold oil out of the injection pump and injectors in a few seconds.
KIT CONTENTS: Read for reference only as this final kit will already be completely assembled.
The STC 100 includes the following components shipped as a full set along with the instruction manual set. Each component is also available separately if you are building your own or trying to increase the performance of any existing conversion.
FM 100 SVO Filter Kit: To read more or to purchase separately put this title in the search box.
Filter Plate Mounting Kit: To read more or to purchase separately put this title in the search box.
Hand Bulb Air Bleed Pump for SVO WVO Fuel Filter: ONLY available in STC 100 Kit
Complete Installation Manual Set: Includes diagrahms and operations and troublehooting guide. Not Available for purchase separately.
Installation Notes: In STC form this is by far the quickest of any kit on the market to install. Building and bolting together the BMFM takes almost as much time as installing the entire kit. Everything mounts in the engine compartment. No need to work in the trunk or under the car unless you plan to add our heated fuel path upgrade or convert to dual tanks. Expect to spend 2 to 4 hours building the parts and 4 to 6 hours installing this kit depending on our level of mechanical experience. An basic understanding of automotive electrical wiring is required. Our detailed and illustrated instructions and schematic drawings will guide you step by step through the more difficult phases of hose routing and wiring hookups. Follow the instructions carefully and you will have success!
The instructions that come with the STC 100 kit are written for and photographed when installing kits in 116, 123 and early 126 300SD diesels. The kit can be installed in other models but you will have to deal with some “issues” and modify the instructions to fit your application.
