Re: Tohatsu 5 hp 2 stroke outboard fuel problem
With a problem like that, the first thing I always do is to carefully inspect the fuel line, squeeze bulb and all the fittings. Check for even the slightest leaks, and check the hose and the squeeze bulb for cracks. If there's the tiniest crack, it can let air into the line. The squeeze bulb is there to pressurize the fuel line. If air can get in through a crack or a loose fitting, it will de-pressurize the fuel line and the engine will be fuel-starved. Cracks are most likely to be found where the hose is connected to a fitting. I have occasionally made an emergency repair that is adequate to get back to the marina by cutting an inch off the cracked end of the hose.
