Got another one for you, the fuel connector going into the motor. A bad seal between the fuel line female end and the outboard male can cause fuel to leak from the connection, air to be sucked in, and the bulb to be squishy. This is happening to me on a brand new (after market) fuel hose/connector...apparently the o-ring seal is a weak point. Ever happen to you? Do you get a 'click' when attaching your fuel line to the motor intake? I don't get a click, and my fuel connector just looks like it is 'hanging off' or pulling away from the attachment. Luckily I have the internal tank that has saved me in this situation...

Ciao, ho un Mercury 3.5 portato a 5 cv con elica in alluminio e carburatore, ora vorrei mettergli un serbatoio esterno, ma non avendo la pompa benzina può funzionare? Alcuni su YouTube dicono di si, ma video OnBoard non ne ho mai visti
