I have a 2006 Tohatsu 6hp four stroke. I bought a Tohatsu tank and hose 18 months ago. I had to replace the engine side hose connector when the O-ring was damaged a month ago. All I had access to was an aftermarket connector. The tank side is the “coax” type.
If I disconnect the hose from the engine during a sunny day I see fuel leaking out of the engine side hose connector. If I release the cap to release pressure, later in the evening the tank collapses from the negative pressure as the fuel cools.
Should the cap vent be closed during the day when the engine is between uses?
when should I disconnect the engine side connector?
when to disconnect the engine side?
Any other tank and hose considerations?
thanks,
harry
