Im trying to cut costs and have removed all the boot lining etc and most of the front interior linings and panels for wiring installation and will be integrating the duel fuel switch into the console myself.

Its never given me any problems in over 50k miles. Cost was Ł1000 fitted, which included a loan car for 3 days whilst the work was carried out. I was using the car on company business for which I was paid a car allowance and mileage allowance, so I recouped the cost in just a few months. As the 2.6 uses a K-Jetronic fuel injection system, it wasn't possible to fit an injector system, which would have been much more expensive anyway (around Ł1750 fitted). I get around 23-25 mpg average, so probably a slight reduction in fuel economy, but it's still a lot more economical than petrol. Main drawback is losing the spare wheel well to the LPG tank and only being able to cover around 230 miles on each tankful. Suggest you do as much research as possible before purchasing a compatible system rather than having it fitted professionally. Hope this helps.

Im going for the biggest tank they can fit which he said was 110 litres across the back of the boot, the 90 litre petrol tank gets about 400 miles on a run so im hoping for about 450 miles on LPG given that it is slightly less efficient. That said it will be about a Ł55 fill up rather than the bank breaking Ł95 to fill it with petrol. havent even thought about the filler location though, probably gonna be in the side of the bumper.
