So when I first put this together, there was a gasket around the upper square glass window where the light shines down into the cylinder. This gasket was trashed and I, thinking it was only there for when this held gasoline, did not replace it.
Well, in a hard blowing rain, water found it's way down through the globe mount, past this upper glass and into the cylinder causing the cylinder to fog up.
So last weekend, I tool the top apart, got the hair dryer out and made sure the interior of cylinder was completely void of moister and I installed that gasket.
Not a week later, all fogged up again!!
Anyone else ever have this issue with a pump outside?
