Installed a Dan-mark last month and today noticed  some gas dripping from the out fitting, went to tighten the clamp i have on the hose which seemed loose and found the Dan-mark almost burned my finger tips off. The motor was running for about 10 minutes. Is this normal or something else?

Sounds like this issue needs more investigation. I've never noticed if my Dan mark's get hot. I'll check them out.

I thought they were opened and closed by an electro-magnetic thing a bob ? Doesn't seem like it would get hot.

Yes, it's just a solenoid but current would be needed to hold it open.

It consumes about 15 watts of power. Over time it will get hot. The cool fuel moving through the valve will help to cool it a bit, but the hot engine area will add to its temperature. After about 20 minutes mine reached almost 190 F and was still climbing.This will definitely burn you but is entirely normal for the valve.

Ok thanks. Thinking about it more it does make sense that current is flowing to keep it open which generates the heat. Thanks for the help BonS.

Yikes!  That is kinda spooky considering gasoline is constantly running through it.

Dan-Marc is a reseller of the Advanced Fuel Components solenoids for automatically cutting off fuel flow when the ignition is off. It's normally on when the engine is running. A popular model is the #111. It's added inline between the petcock and the carburetors.

Do you think something like this would be useful?

I am guessing that would make it even more efficient at absorbing heat from the area above the engine.
