cheers for the replies guys some good info there, im not running duel infection but i do have a return to the tank, looking at the answers it makes sense about the hot fuel returning and i suppose the less fuel in the tank the more it will heat up as a whole.
just wondering if there is a quick fix like a vented cap, both mine say non vented, i know the proper way would be to remove the tank and unclog the breather spout but that’s a mission in itself due to my modified filler neck, i would have thought that by the amount of pressure encountered it would have forced fuel past the shut off valve in the carb?
