Well, JamesV6CDX's LPG conversion went very smoothly, the kit seems to include everything required and there were no issues whatsoever fitting it to an Omega.
I also heard back from Jeremy today regarding the bulk buy I proposed and he's prepared to offer a discount of 10% on the front end kits giving a saving of about £50 off the EBay price of £495.
Regarding the fitting, James and I were thinking about this at the weekend. 3 of us spent the best part of a weekend getting his car up and running. We did everything except fitting the LPG tank and mounting and connecting the filler and it was pretty hard work. We did spend a bit of time chasing round for parts on Saturday morning and the obligatory breaks for tea, bacon sarnies and (later in the day) beer. I'm not sure that we'd get a lot of kits fitted at an "LPG party" if we were going to tackle complete installs. However, as long as people are happy to tackle the straightforward bits themselves (tank and filler fitting, pipe & cable routing, vapouriser mounting, etc.) I think a party where we finish off the details and do the tricky bits, make electrical connections, check systems over and adjust fuel maps would be a good idea.
Having seen James' install I'm certainly happy to go ahead with it myself. Do we have any more who are prepared to firm up their interest in this?
