Today, (The 3 of February 07) is my Tenth Anniversary of the start of my veggie motoring--It was ten years ago, that I first took the plunge and added vegetable-oil I bought in Tesco's to the tank of my Mercedes 300 Diesel.....Back then, everyone thought I was mad....

Since then I have built up a vast experience of all types of Diesel vehicle and engine, as well as a variety of 'Conversion' solutions I developed. I have extensive experience of BioDiesel production on a Commercial basis, at my 'Day-Job', as a BioDiesel Plant Manager with Sundance Renewables. Maybe I have proved that  I wasn't quite as mad as they first thought...

Due to recent interest I am now able to offer vehicle conversion kits for most Diesel fuelled vehicles and engines. I can also undertake full installation of the needed conversion equipment to your vehicle --Email your full vehicle details for further information

I am able to offer the SMARTVEG system taylored to your application as well as more economical systems for certain applications. Please Email me with your requirements and the vehicle make/model and age.

Technical Consultancy for vehicle and other Diesel engine conversion as well as Consultancy for fuel injection pump/system modification is also undertaken. Certain Technical Consultancy however will need a Confidentiality Agreement to be signed.


Veggy Oil Conversions for Post 1999 Mercedes-Benz CDi vehicles now available, including Sprinter, Vito and Passenger-cars. Also certain other 'Common-Rail' and HDi types catered for.

- D.I.Y. Veggie Mechanics and Modifications

- Dedicated to all Diesel systems and engines for use on Vegetable Oils and Alternative Fuels.
There is now a huge amount of information on running Diesel Engines with Vegetable oils out there in Cyber-land, Some very good, others very bad! Its difficult for a newcomer to tell good from bad. All the information, methods and modifications Ive detailed on this web-site have been tried and tested by myself, over the last 6 years or so, on a variety of different vehicles and engines. My advice to anyone thinking of converting an engine to use Vegetable oils is research the subject as much as you can. Start here, and the attached links to both Darren Hill's Website, and the Goat Industries sites. There is a Forum at the Goat-Industries site which has a wealth of information, and a list of converted vehicles. This Web-site will deal mainly with the Diesel Injection pumps, Injectors and modifications to them, rather than the best way to set up additional plumbing etc, which has been covered elsewhere at great depth on the Web!. Currently, this web-site is funded by the various banners appearing at the head of pages, I niether endorse or recommend any of the companies or services. You will need to use your own judgement in this.

- BOSCH EPVE Axial Plunger Distributor Fuel Pump
This fuel pump is one of the more popular injection pumps and was the mainstay of BOSCH fuel systems for cars and smaller commercials. It has been nearly superseeded completely by the later VP37 and VP44 "Fly-By-Wire" Electronic systems where cost does not warrant the use of Common Rail and Unit Injector scenarios. The Mechanical EPVE is probably one of the best "Rotary" type pumps for Vegetable oil use, often just a simple re-routing of fuel return to the pump inlet is all thats needed to give good performance. This type, as with most systems benefits from an additional lift-pump fitted near the tank to reduce "strain" under high fuel demand conditions. The later electronic VP37, uses the same pumping principle as the earlier mechanical pump, but uses electrical actuators for fuelling and timing alteration, and care should be taken on the fuel oil quality so as not to damage these components. The VP44 series is quite different, as it follows the same pumping and distribution principle as the Lucas/CAV series. It has shown to cause problems with alternative fuels.


- Delphi Lucas/CAV, DPC Radial Plunger Pump
Made by a number of Companies under Licence, The DPC fuel pump may be named CAV, Lucas, Lucas/CAV, and RotoDiesel This pump was Lucas/CAV answer to the Bosch EPVE above, and is found in the same sort of application. Quite often, the vehicle maker will use both the Bosch EPVE and the Lucas DPC on the same model in their range. It is still fitted to certain new vehicles, a tribute to the design, as it complies with the new emission regulations in force, needing only detail changes The basic design has been around since the fifties in various versions, such as the DPA and DPS. Unfortunately, these otherwise excellent pumps are not well suited to the high viscosity Vegetable oil, and can fail without warning, especially if unheated oils, or the pump is cold when Vegetable oil is used. The usual mode of failure is seizing of the distributor rotor in the hydraulic head, causing the rotor driveshaft to shear. Due to the cost of the affected components, the pump can then be considered unrepairable. However, there are many of these pumps giving good service on Vegetable oil, but nearly always where a two-tank set up with additional fuel heating. The fuel changeover to Vegetable oil only when the pump is completely warmed up. The pump is purged by standard diesel prior to shut down so diesel is present in the pump for the next cold start. The above method of use should be considered mandatory with this make, (and even then, the pump may still fail) unless internal modifications have been carried out to improve rotor lubrication.

- Stanadyne DB Radial Plunger Distributor Pump
This American pump is not that common in the UK, usually found only on the "Japanese Dodge" engine found in some older Renault trucks and minibuses, being made under Licence by Diesel Kiki It follows the same operating principle as the Lucas CAV This pump can suffer the same fate as the Lucas CAV, as its construction of the distributor rotor and hydraulic head are very similar, These pumps should only be used on Vegetable oils where the pump and fuel have been heated to full normal running temperature, if no internal modifications to improve rotor lubrication have been carried out.
