Gas leak from lower unit

[Mikeiv]

I have a Yamaha f115bet 2018 model, which recently developed a gas leak from the lower unit. I changed the low pressure pump the leaks stopped for about a month and began once more . Any suggestions to this issue

there should be no fuel in the lower unit, so why should it be leaking from it

Maybe it’s leaking from up around the power head and drumming down inside the leg and dripping out the lower unit?

But I could see the gas bubbling up from the water

This I will give a check today

So after viewing today I notice that the gas is coming from the carbon canister and down its drain line
