Help with fuel transfer valve

The fuel flapper/ball/whatever it is in the fuel neck can seep/leek when over filled. Ask me how I know. I would put some kind of shut off, electric solenoid valve or like to keep from over filling.

X2!

Common complaint on gassers. With capless systems on gassers as time goes on, dirt, grime eventually builds up on the filler door and gasket leading to the dreaded Evap system "slight" leak code and light.

Handling Diesel is even a dirtier more grimy affair so I suspect leakage may be even a bigger problem with them.. But most won't know since the Diesels do not have a evap system test..

Common fix that works is to replace the capless filler neck with a standard filler neck with removable cap..

Motorized valves are out there but they add in a motor control circuit board and some sort of spring return to shut the valve when powered off.. Solenoids by their nature also use a spring to snap the valve shut when not powered.. Both versions can be prone to mechanical or electrical failure.

I would go with manual fill valve for mere simplicity whenever possible. You HAVE to eventually stop somewhere for rest stops and meals, just open the valve and transfer some fuel while you are taking a break..

That is what I do with my gasser, I carry a 15 gallon landscaper tank and use a electric fuel pump and hose to manually transfer to the vehicle tank..
