I always sink the barracuda and the hoses and fill them up... I know this part is okay... but I'll look for small holes in hose.

When I saw all the bubbles coming out the jet, I thought of the pump. So I changed the rubber in the cap that we can take off on top.
The old rubber was cracked. But even with a new one, nothing changed.

But will look for the hose... but I don't feel very optimist about this option. Will give comebacks tomorrow. thanks
