Any thoughts on what to use to seal the gap between the fuel line and the generator cabinet (where the fuel line enters the cabinet)? In our setup, we have rigid black pipe (cast iron I believe) entering the generator to make the propane connection to the generator.

I was originally thinking of using copper scouring pads (no soap.) :) I have used this in the past in other areas with great success since they can be easily formed and do not rust. However, with the vibration associated with a generator, I am reluctant to use this since the pad is rough and vibration could cause wear on components that touch the pad. With colder weather, I want to keep critters (probably just field mice) out.

We caulk all openings with NP-1 and keep mothballs inside the units keeps all kind of critters out.

NP-1 is a good idea. I've used polyurethane based caulks/sealants (they're excellent), and our roofer swears by NP-1. Thanks :)
