so, if i was to have a D reg 90....

what would i need to do?

and wheres the best way of getting info on making it as i only seem to find long winded info on stuff for using as 20% with 80% from the pump

thanks for the info

I've been looking into running mine on 100% vegetable oil - it's got a Transit engine but it has a Lucas pump like the 2.5 N/A Land-Rover engine I spoke to my local diesel engine specialist (who used to work for Lucas) and he said that a Lucas pump should work O.K. with veg oil provided that the oil is heated up before it goes into the pump (Otherwise the oil is too thick and can damage the internals of the pump). There are heat exchangers on the market which plumb into the cooling system and also electric heaters. The problem with both is that when cold starting the engine the pump is full of cold veg oil and this can break the pump. The solution is to have two fuel tanks and a switch over valve - one tank for diesel, one for veg oil. The engine should be run for a minute or so on diesel before being switched off. It seems to me that it would be very easy to forget to do this. He also told me that he is having to replace a lot of seals on fuel pumps which run on veg oil.
 
yeh i heard about having a tank to purge the system of veg oil

so is that straight veg oil?

did you see the gizmo in LR monthly to help stop fuel and biofuel degrading the components...?
 
Yep he thought it would run O.K. on 100% veg oil with a 2 tank system. I didn't see that gizmo. How does it work? - an additive? My guess is that a 2 tank system would rot the seals slower because the pump would be full of diesel most of the time. Even if the seals need replacing after a couple of years, the fuel saving should more than cover the repair costs especially if you take the pump out and refit it yourself.
 
so literally, neat veg oil from say chippy, filtered? purge the system before you stop so it starts on pump diesel and then have a fuel heater for the veg oil?

umm, it worked via magnets and stuff i think, ill find a link, im not convinced it works, but has a lifetime garuntee as i remember.

looks like the defender iv found may be sat on my drive as of next week
 
It might make life a bit easier if you find a Landy with a 200 TDI engine in it which will have a Bosch pump. People say these pumps work O.K. on 100% veg oil without a 2 tank system. I'm guessing the 300TDI engines have a Bosch pump too.

Damn... that kit is expensive! I was thinking of making my own heat exchanger along the lines of a central heating hot water cylinder, by finding a steel container, coiling some copper pipe inside it (which the fuel passes through, solder up the joints and add an inlet and outlet so that water from the cooling system flows through the container. I think it would be good to fit a thermostatically controled electric heater between the heat exchanger and the pump as it would heat up faster than the heat exchanger. Once the heat exchanger is up to temperature the electric heater would switch itself off.
 
I don't bother anymore btw. I can't be arsed messing about filtering used oil even if I could get it and diesel is a fair bit cheaper than svo now
 
SVO is about 80p/l in Tesco now so it's still a good saving - adding a twin tank is pointless unless your really tight and dont mind doing the (aprox) 50k it will take to recoop your investment

Lucas pumps are ok with SVO however you do have to be sensible - don't expect them to last long if you run high SVO percentages in near zero temperatures and if the seals do go get them replaced with viton seals
 
i've done in excess of 10k in vehicles using lucas pumps on SVO and know people who have done lots lots more, i'm not saying they will last forever but as before if you are sensible you will get plenty of miles out of it - and seeing as you can pickup a good used pump for less than £50 these days it makes sense to run it till it breaks
 
I did it for about 10,000miles too, it does run fine... I just know that some people would not want to think of their pump as disposable.

I got a new one in mine and its running a treat now. I am going to run it on derv now though because I am doing all my miles in the 300tdi.
