Fuel Tank Selector Valves

As well as developing our own solenoid valves for vegetable oil, BioTuning are the authorised UK distributors for Pevekoil.

As described in the parts section, the fuel select valve is used in twin tank systems to select between the startup/ shutdown tank and the vegetable oil tank. They can be manually operated by the driver using a switch or a more sophisticated automated control can be used to select the fuel (eg a temperature based controller). The valves we stock have strong pedigrees in the automotive industry and are highly regarded internationally for use with vegetable oil.

BioTuning 3 port solenoid valve for vegetable oil conversion of diesel cars

BioTuning 3 port solenoid valve for vegetable oil conversion of diesel cars

After a great deal of work on design and testing we are pleased to offer our 8mm 3/2 way vegetable oil solenoid valve. Designed especially for fuel tank selection in twin tank vegoil conversions, they have better specification than any other 8mm solenoid valve on the market. Our valves are ideal for conversion of smaller engined cars and light vans such as golfs. For larger vehicles, the BioTuning LARGE BORE valves or Pevekoil valves are better suited.

BioTuning LARGE BORE solenoid valve for vegetable oil

BioTuning 3 port solenoid valve for vegetable oil conversion of diesel cars

BioTuning 3 port solenoid valve for vegetable oil conversion of diesel cars

BioTuning 3 port solenoid valve for vegetable oil conversion of diesel cars

The BioTuning LARGE BORE solenoid valve for vegetable oil conversion. This valve is ideal for use in twin tank vegetable oil conversions on vans, pickups, 4x4s, campers and light commercials. It has an especially high coefficient of flow to minimise flow restriction and reduce the chance of fuel starvation - ideal for fuel hungry vehicles when running on vegoil which is slightly thicker than diesel fuel even when heated. It has anodised aluminium construction with stainless steel internal components and Viton seals. The valve can easily be opened and reassembled in case of blockage or to service the valve and replace the seals (see below for the Viton replacement seal kit).

Supplied with a clear connector block housing an LED to indicate when there is power supplied to the valve - this is a great when installing and testing the valve to check your wiring and switch are functioning. These valves have very high closing pressures and 12mm internal bore.

  • 3/2 way solenoid valve
  • Specifically designed for vegoil conversions
  • LARGE internal bore for larger vehicles (12mm)
  • choice of 8mm or 10mm OD brass fuel ports
  • choice of 12 volt or 24 volt DC
  • VITON seals: -20°C to +130°C fuels
  • Very high closing pressures
  • Stainless steel internal components
  • Anodised aluminium body material
  • Weather tight clear connection housing including LED power indicator
  • Integrated M5 mounting holes
  • Also suitable for petrol and biodiesel
  • Supplied with installation guide
  • Easily serviced. Replacement Viton seal kit available

Twin solenoid valve control (switch and LED)

Control pack for twin tank kits. Comprising Double Pole, Double Throw ON-OFF-ON switch and dual colour LED for controlling a pair of solenoid valves giving 3 modes.

Supplied with easy-to-follow wiring instructions to give the following operation.

  • Diesel mode. With the switch in the O position (0 valves powered) both the supply valve and the return valve are unenergised (off). The fuel is drawn from and returned to the diesel tank. The LED is off.
  • Vegoil mode. With the switch in the II position (2 valves powered) both the supply valve and the return valve are energised (on). The fuel is drawn from and returned to the vegoil tank. The LED is green
  • Purge mode. With the switch in the I position (1 valve powered) the supply valve is unenergised (off) and the return valve energised (on). The fuel is drawn from the diesel tank and returned to the vegoil tank. The LED is red

Operating a solenoid powered twin tank kit with this control pack is as follows;

Run the vehicle in the diesel mode until the engine is warm. Switch to veg mode when the engine has reached operating temperature. Run in this mode for the rest of the journey. If the vehicle will be left to cool down before the next journey a purge is necessary. Run the vehicle for around 60 seconds in purge mode and then switch to diesel mode and run for a further 30 seconds. The vehicle is primed and ready for the next cold start.

The switch fits a cutout of 22mm wide and 30mm tall. this is the size of typical blanks in many vehicles. The photos show the switch installed into a blank space in a 2003 VW Polo.

The LED comes with a mounting bezel which pushes into an 8mm diameter hole. It is connected to a pair of flying leads and is surge protected. The LED gives good bright and clear indication of which mode the valves are in.
