Re: I Dunno What It Is
You mean the hole in the floor? Actually, maybe it's someone's attempt at reducing the fuel smell in the cab...

Re: I Dunno What It Is
Is it mounted to the floor? It kinda looks like a breather on front of the engine oil fill.

Re: I Dunno What It Is
Could it be one of those air freshners you buy at the parts store, that just got left behind after the truck seat was removed?
Seriously, I never have seen anything like it other than a breather on a engine. But the fuel vapor idea seems logical..

Re: I Dunno What It Is
I think it is to let the farts out of the cab without putting the window down, see the location?
Rigging ingenuity at it's best!!!!

Re: I Dunno What It Is

Re: I Dunno What It Is
What happend to the rest of the truck? could it be some kind of a vent or a breather for a vac booster under the cab.I saw a 3500 gmc once that was supper HD it had 18" wheels with a big bolt pattern like a c 50 or 60 and it had a brake booster under the cab on the frame like my old c60.I dont know why it would need to vent inside the truck though,just throwing it out for consideration.

Re: I Dunno What It Is
You know,Old Chev,that could be it.I never saw the rest of the truck.I believe it was a race car hauler.It`s a Custom/air cab.I didn`t think about those HD 3500s having different brakes.
Maybe Big Al`s right.That was my first thought.Maybe it`s like propane injection but with methane.

Re: I Dunno What It Is
I have seen them before in c-40 and bigger trucks, but never paid attention to the reason.

Re: I Dunno What It Is
What would you vent into the cab? I haven't a clue!Maybe it was to keep the air tight cab from sucking in on the driver!

Re: I Dunno What It Is
It could be for something that needs venting like a rear axle does. For example, an axle does not give off any harmful fumes and it has a vent that is attached to the frame rail to keep it up out of water if crossing a wet area. Maybe there is someone with one of the C50-C60's who can clue us in as to if it is original and what is mounted under the cabs on the big trucks (?)

Re: I Dunno What It Is
Maybe where the owner lived it would flood frequently, so he decided to make a drain.
