Nice to see how the "professional" kits work. Looks nice n clean down there to.

When I made my conversion up I didn't want to confuse thing with auto switching temp controls to start with, now I can understand that a company producing "universal" kits would need to keep the temp above a certain point to stop Lucas pumps self destructing.

Being able to switch manually offers the chance to experiment and use the best data logger invented, the space between our ears.

The "Bosch" pump fitted to the Bongo is temperature tolerant unlike others..............Nudge nudge wink wink, and will cope with thicker oil. Now I hold my hands up and admit I have no experience of using waste veg oil with the water and fat contamination that it brings into the equation.
It is possible CV would have problems switching at the temp that I do and his system provides a safeguard but from previous posts I suspect his system WOULD work well down to a heat exchanger temp of 35c or lower. As long as there is a good purge before stopping for long periods.

The only "fault" that I can find design wise is the point the IP return feeds back into the system.
IMHO feeding it into the system just before the heat exchanger makes better sense, this warms the cooler veg offering the heat exchanger less work and a higher outlet temp.

Thanks for your reply tgp.

Yep your right ...if i was doing a diy conversion i would loop the heatexchanger thus heating both fuels.It DOES have a benifit and i did this on my lucas berlingo conversion.
I had a much bigger heatexchanger fittet to that and a heated filter.

It would be heated fuel filter b4 valves and looped h/e in circuit.The prob with this is it take ages to flushas your not only flushing a larger loop you have the h/e to flush too.

On my lucas conversion i had a temp thermister/gauge of ip return just off off the pump,and a coolant temp senser probe as well.
The ideas behind this is not only you know your heatexchanger is hot the return from pump is hot,and only switch over when that gets to 50 oc.The idea here was to make sure everything was hot b4 switching over not just fuel.


On my kit(bongo) I van get away from looping heatexchanger as the little glow heater(not glow plug) comes on to aid warming the oil on the return if its low,like a top up.

I too can changer over whenever i like,there is a manual switch or auto.But lately ive been switching over when coolant is upto temp and engine using the aid of my hydon alarm which is on back of block.

[chipvan]

Ps you could alway make a senser that pings on a led on dash when coolant/fuel or both is hot.

or have a guage/gauges

You could get a temp contraoller so switches at your set temp as well,loads on ebay ar ethey called pid?

I have switched over to veg as soon as started engine on diesel from flush down,the veg goes into loop slowly and by time engine up to temp running on 100% veg.BUT i dont do this often tbh,just did it as a trail.
It worked fine when engine was cold 9 oc.spose its on a blend when 1st starting then more and more veg is mixed in loop..still it was fine and no diference to driving at all!! and thats on almost 100% wvo!!! from cold.

But dont think its good to do this often

Hi there chipvan,

finally got my supply of WVO sorted, Thanks for the advice re filtering and settling very helpful.
have now put together my own conversion kit
got a question for you
Which hose did you use to your heat exchange? was it the 12mm bottom of header tank one? That's the only one I can see that is standard 12 mm?

The problem for most of us average joes is even if we got to grips with fitted a conversion kit, we've no idea where to reliably source suitable veg oil at a price that makes economic sense of the whole thing. If only that little problem could be sorted
