Hi, this interests me as well as I am planning to convert mine, just as soon as I get working software. Another forum on the web, www.lpgforum.co.uk has plenty discussion on LPG, but it tends to be answered by installers. However there are some good bits of info. One chap suggested taking the hot water feed from the hose that goes into the top of the expansion tank. Does anybody else know the water circulation arrangement on the Omega ?. Which bit gets hot first and can you tee in to it ?.

Do this !

Hello Paul - you have been on that forum as well I notice - I recognise two other posters one who certified my DIY and one who fitted to my last car.

Thanks Martin. Yes I have been on that forum for quite a while, although I only pop in occasionally. There are certainly some knowledgeable folk on there, likewise for the newsgroup uk.rec.cars.fuel.lpg

Can you suggest a good source for pipes and tee pieces? If I'm going to change the coolant routing I want to make sure I have all the right stuff beforehand as it's such a pig to get to the necessary parts on the V6. I don't actually know the diameter required

Cheers.

Like these!

You also need about 2m of pipe which fits the evaporator and plenty of jubilee clips

Thanks again Martin. I just had a look at your picture (had images switched off earlier, d'oh!) and that's exactly how I was thinking of doing it. I just wasn't sure how the input to the HBV is connected hence I didn't know if I'd be able to tee into it. Hopefully it's not too bad a job reaching round the back of the engine.

Do you know the diameter of hose I need? The vapouriser is currently plumbed into the pipe that goes into the bottom of the expansion tank from the metal pipe that runs along the side of the block, so I reckon that diameter will be ideal. It looks the same diameter as the pipes connected to the HBV.

Cheers
Paul.

Diameter - nope - measure the external diameter and take off say 4 to 6mm, I would guess and 16 or 20mm internal.

I had the scuttle off wipers out and plenum off
