On Pigpen 867, Why is gas cap leaking/venting on to bottom of hood?

Recommended Posts

Trina's 867 has some gasoline around the cap on the tank but also on the underside of the hood. Not at all what I would call a profuse leak but obviously something that shouldn't be there.

 

What's the remedy?

New cap gasket, not fill as quite full. I don't know just some ideas.

That's one of the things I was thinking as well. 

How do you check for one of these to have a clogged vent?

Lots of different caps My lawn ranger has an inner cap that is pitched to keep any gas that get splashed up to run back down.Dont't know about yours but simple test blow into the vent hole

The gas cap should have some type of baffle in it. And not be just a hole in the metal cap for the gas to escape when sloshing around. The vent hole in the baffle should be offset to the vent hole in the cap. The gas will have a difficult time getting from under the hole in the baffle to exiting up through the vent hole in the gas cap. Some caps used a paper gasket type of baffle, some were cork and modern caps are plastic with offset holes for the vent

This is L-107 cap 2 pieces ans wallfish said the holes are offset and the inner cap slants to one side to return and splash back to eh tank.

Just spit balling, can you make a gasket with off set hole that stays in place with edge friction? Keeps vent action but does not allow gas to slosh through off set holes?

 

This concept:

Those old gas caps were two piece with a cork or rubber seal is it all still there?  It's probably rusted shut, take it a part remover the rust  poke the hole or holes open oil it provide a new seal.

Here is one off an 8 hp Briggs that is rusted shut.

I wonder if that's just an 867 thing because mune does it too. I just keep the tank at about 3/4.

Trina checked it and cleaned it up a little. We'll see later...
