Fuel Tank Bubbles?

They are connected under the rear of the upper tank. Lift it, you will see them. Two of them have a joint under the seat, very front left. They emerge near the gear lever. Behind the alloy. Clipped in place at the bottom rear left of the sump.

You will have to remove the tank to get to them. The rear of the tank cannot be lifted very much at all because of the large diameter hose that connects the upper and lower tanks. Your '05 is 19 years old - a close inspection of the hoses between the upper and lower tanks is warranted. You do NOT want that big hose to leak, spilling gasoline onto a hot engine. Honda wants us to replace the spring clamp when you remove it and sells the new clamp with a clip on it holding it in the open position. You will need a good pair of channelock type pliers or hose clamp pliers to squeeze the tabs in order to allow removal of the hose (the same goes for the smaller one). IIRC, the hose ends are two different diameters.
