Evap Test Failed. Replacing All the Hoses and Gaskets

I failed the cali smog the other day due to a leak in my tank or evap system. i know its not the canister because for the test he pulled the vent hose off the canister and clamped it off. so its somewhere between my tank and the canister. replacing all my hoses and need to know what hoses i need. i cant find anything that just says "replacement Evap hose" or anything like that so any info would be very much apreciated.
thanks in advance

I think those are just regular rubber hoses ?
Take them off and measure how much you need and take a small sample of the hose to a auto store and see what they got. I think you might have to drop the tank though unless you have a big enough body lift to get your hand in to the top of the fuel tank

I would go with fuel injection hose. It's a little more expensive but the fuel vapors attack the rubber on ordinary vacuum hose. It'll last a while but they'll get soft and break down eventually.
