I have now fitted the fuel heater to enable the engine to run on vegoil (SVO). It’s fitted between the fuel filter and Kenlowe Hotstart, and uses engine coolant running to the cabin heater matrix to heat the fuel to over 80oC. This means I can now take advantage of the UK government’s decision to exempt users of duty on 2,500 litres of bio-fuel per annum. By gravity filtering used vegoil from take-away food shops, I hope to run on free fuel all year round, just using enough diesel to warm the engine before changing over to run on SVO. I’ll post some photos when I write a report on how it runs on the SVO.
