Come on Terry I get at least 625 k's for 160l, 600 is just ridiculous.:p
I forgot to add the OA tank was at least $600 cheaper fitted as well. Though I would gladly have paid the extra to have it fitted by competent mechanics instead of the monkeys that fitted mine.
I also had to replace the large breather that was supplied as it was not fuel compatible and was de-laminating. The monkeys also plumbed it into the vent for the charcoal filter instead of the tank breathers and I was getting fuel leaking and my fuel vapour recovery system was filled with fuel.
