Looking at putting the Lane on LPG and just wondering whether a 6 cyl setup will suit or not?? If not whats the rough price on a new system??

Not sure about the 6cyl system, but I paid about $2,800 a couple of years ago for a new system for my Lane. Got the $2k grant from the gov't, so all up $800 out of pocket.
I have heard that the grant has been reduced or even axed entirely. Not all bad, the install price will probably come back to respectable price without the grant feeding the greedy pricks pockets
