There are plenty of aftermarket inline fuel heaters out there, but you'd be better off with a fuel/coolant heat exchanger.
No, assuredly UK BX's were indeed fitted with the electrical diesel heater in question, my grandfather purchased an early MK2 19RD estate when it was about 3 years old (registered late '86 IIRC) which was fitted with a Bosch pump and the electrical diesel heater. I believe C15D vans of the same period were also so equipped...

Phew, I was certain I had seen one on an early RD, My G reg TRD however had the other nasty heater at the back of the block which had to be bypassed as it was sucking air on the mildest of inclines

My dilemma with veg oil is the fact that I have a weekly source of around 80l of WVO for the princely sum of £12

You need to do a Bosch conversion Ed. Not difficult, just get a pump, the pipes and the injectors as a set, along with the pump sprocket and woodruff key. Lucas pipes, sprocket and injectors are not compatile with the Bosch.

The pump cradle will suit both types of pump although when fitting the Bosch it's necessary to unscrew the mounting studs and move them to their alternate positions.

Electical, fuel supply/return, coldstart and throttle cables are all pretty straightforward.

Have any new pump you get hold of overhauled and resealed before fitting.

Timing and pump fuelling will need a tweak once it's all up and running.

Instead of knackering up your BX with the veg, consider a Mercedes 190D. As David said in the other thread they run seemingly without harm on veg, and you needn't worry about *when* (not if) your pump will die. Winter particularly is a bad time for running on the veg...

With the Merc you should be able to run 100% wvo with little problems, provided the fuel is filtered and reasonably de-watered.

Right I've been a good boy this year so no reason why Santa shouldn't deliver this:

Preferably not by Parcel Force as I would like it to arrive in the above condition

So did Santa bring you one Ed?

Now, the one in the picture is one for a Turbo engine as it has the LDA (UFO) on top. More than likely it's for a 1.9 Turbo

These will work on the 1.7 NA engine but as a guess they'll overfuel a bit in standard set-up and it may be better to tweak it down slightly.

Better if you can get a pukka non-turbo Bosch. They look much the same but don't have an LDA.

This is a non-turbo one...

Absolutely. The top image is from a 1.9TD engine. Although it would work on a non-turbo engine, it seems a bit of a waste of a turbo pump.

Likewise, it will work on a 1.7TD, with the fuelling wound in a touch. The "genuine article" 1.7TD injection pump (with the extra waxstat unit on the front) is a more robust pump though, and allows you to manually adjust the injection timing too (rather than relying on the electric advance unit on the pictured pump)

Err ummm, didn't mention it but mine is a 1.7 TD

. That pic and others, plus interesting veggie lubrication issues to be found here

In that case Ed, the one shown in your original picture will be fine with the fuelling wound back just a tad

Did you get the Bosch set up ok? I've now moved to WVO with the Xantia, which is running suprisingly well on it...

I've been running my estate with the Bosch pump on SVO whenever I can find it cheap enough (seems that the used stuff has all been snapped up round here) just lately Tesco have had it for £7.50 for 10 litres which is a reasonable

saving in my book. This was the KTC stuff which was in a cardboard cube with a placcy cube inside it. I rarely (especially in the winter) run any more than 50% mix and do indeed find the car runs very well ( if not better) on it. I've got a feeling that that offer finished this week so just eep an eye out for the next one. I did see that Asda were doing 15 litres for £14.53...(same brand).....which is still cheaper than the diesel round here...just!

Don't forget running a car on new vegetable oil means you should declare it and pay the appropriate amount of tax. Which is the same as tax on diesel fuel. I therefore think some of you are getting confused and must be running your cars on recycled vegetable oil which means you can use 2500ltrs per year free of tax

i had been under the impression that it did not matter wether it was new or used oil you were still intitled to that allowence
BTW the reason the allowence was brought in was because so many people registered they could not cope or afford to administrate it

My understanding was that the allowance applied to people manufacturing up to 2500 litres of biodiesel, not using up to 2500 litres. I wonder (and this has probably been done to death on the internet somewhere) whether it could be argued that simply pouring 25 litres of SVO into your fuel tank constitutes 'manufacture' of biodiesel?

Its perfectly legal to use either SVO, WVO or Bio-diesel or in combinations of any & not need to declare it unless you are making or using more than 2500 litres per year.

You can use 2500 litres a year of any oil (SVO/WVO) without paying anything to the taxman.........my mate who was a long distance Trucker tells me they used to do an oil change on the side of the road on a long trip sometimes and pour the used engine oil (about 20 litres )straight into the fuel tank....no probs.
