all interesting answers, but i dont have the bosch pump in mine anymore, it faild a few months back and i replaced it with a spurious one. so that kinda sorts that one out.
im gonna keep looking in to the bio diesel thing and see how hard it would be to make a kit to do about 100Lts at a go. i mean i have access to nearly an unlimited supply of the stuff no point in a company charging me money to take it away when i can use it for myself.
Well - did you go the Bio route?
I started with 20% WVO then up to 50% in the summer. When the vehicle got harder to start - time to decrease ratio.
I then converted my P38 using a 20l startup tank. The main tank holds the veg. I have pipe in pipe heaters from the tank to the engine bay, where the WVO then goes through a flat plate heat exchanger, then a heated fuel filter before the final changeover block where there is a small electrical heater (thermocouple controlled).
I probably went overkill. Even putting a small pump in to cycle the WVO back from the final changeover valve to the heated filter. This was to ensure that all WVO was heated before it went to the injection pump. The pump only cycles for 15 seconds before the changeover from startup diesel to WVO.
The original fuel pump in the tank failed after about 3000 miles of pumping veg. I removed it and fitted an external gear pump which works fine.
I monitor the WVO temp at the heated filter using a thermometer with a remote probe which is pushed under some pipe insulation that I surround teh heated filer cannister with. Generally at this point the readout indicates 60+ c, having checked this with an infrared probe its underreading by around 8 - 10 c. so I really have oil heated to 70+ C.
Now - filtering - that' a whole different story!
Cheap fuel
- I tell myself that anyway the vehicle still swallows lots of cash in other areas - latest one is an ETC problem which means I cant get it MOT'd.
