    Anybody wanna buy any snow? I have plenty of plain ol snow, you know, some leaves, sticks, dog poop, and discolored a little bit. It's $10 for a heaping PU load. I have plenty of pure white virgin snow. $25 dollars for a heaping PU load. (BTW this isn't a "snow job")

    I have a question about this gas tank float material, that's in the picture. A couple of years ago I bought a Stewart-Warner gas tank float ***embly and vintage looking guage kit. Went ahead and made the pick-up, vent tube and the SW float ***embly to fit my '32 tank.

    Got ready to ***emble it all the other day and noticed the "weird" looking float didn't resemble what common float material I have been used to seeing. I have seen solid cork, something like styrofoam, ping-pong ball material, plastic like what milk jugs are made of, and the usual br***/copper floats.

    I inquired on the Stewart-Warner web site. All they stated was, it's made of a solid material that will not saturate or get any "pin-holes."

    But look what happened when I put a br*** float and the SW float in some water! I don't remember seeing the copper/br*** floats riding that low in a liquid. Nor have I ever seen a float riding "kattywhumpus" like in the picture. (when I had the picture taken, was the first time either float had been in any kind of liquid)

    Is this "new" material SW is using, any good? Wouldn't the plastic float ***embly wear quickly putting a uneven strain on the metal float arm? FLOAT.jpg

    No doubt some sort of closed cell foam.

    wouldn’t worry about it floating wonky, it’ll still lift the float arm ok. Why would it ‘wear’?

    My only worry would be how does the plastic hold up to the ethanol in most of todays gas?

    Put the br*** float in near boiling water and it'll expand the air inside it.
    You should see air bubbles where a hole is.

    We've had no luck with br*** floats on Tri-5's so the fix is a plastic float for a 64-73 Mustang or CJ Jeep.
    They clip into the same place

    here [only $6]

    No worse than a plastic gas can

    When I worked in a local tri 5 parts store we stocked br*** floats from the local parts warehouse.
    When the after market float failed we sold them a different br*** float. I’m thinking for Fords.

    The alcohol in the gas will eat a br*** float. When I got the Astorian the gas gauge did not work. when I removed it the br*** float was half eaten away. I only use non oxy gas in my old cars, but it had that **** in it when I got it....
