vented box for Honda 2200 generator

Wish it not such a pain to post pictures here. The Honda cap itself will stop fumes for the generator. Gas fumes are heavier than air so a simple vent in the bottom of the box will keep fumes to a minimum.

I am in the process of building a new box for my Honda and will be running the gen in the box. I will have a vent line running from the extended run tank to outside the box, gas tank and gen are in same box.

As long as there are some open drain holes at the bottom or even just a poorly fit seal at the bottom, it's fine.

Gasoline vapors are heavier than air so they drop down naturally and then blow away.

Occasionally they blow up. ;)

Other than in movies where the rules of physics don't apply...

when was the last time you saw a car randomly blow up from gas fumes collecting below the car?

There is a reason gas boats have bilge fans that you run before starting the engine and cars don't.

You are correct, I have never seen a car blow up from gasoline fumes.
However, I have seen gasoline fumes travel across the ground about 20' and ignite from a fire. I think it's called a flashover? I don't know.
I do know it was scary.

I used one of these and was very happy with it. I had mine custom built a bit wider so that I could put a 2-gallon gas can in the same box. One of those tall, wide, and narrow plastic gas cans that people carry on ATV's.

Then a vented box won't solve the OP's issue...doesn't matter if they just have vents on the bottom or also on the side.

Then again, how much fuel was dumped to have enough fumes to travel 20ft and then ignite? Gasoline is a lot harder to light in open conditions than you might think.

Sometimes not hard enough!

Like when I soaked a red ant nest with gas, bent down, and lit it off with my cigarette lighter.

I'm still waiting for all of my eyebrows to grow back!
