Took 'em a while, I think half a day, they had to purge the fuel system, pump out the tanks and fill at least one with the proper diesel fuel. We know a couple lads who were involved and they told us that once the fuel systems were purged and the old batteries replace, the beast fired right up. Don't know the story yet on the IS 2 but it was probably the same drill, purge, new fuel, new batteries and up he fired.
