You know, the kind that has a solid plastic float that operates a flat
screw type axle to turn a needle in the cap showing the amount of fuel left.
These plastic floats seem to allow gas to permeate the float, giving a
less than correct fuel level.
I suppose I can buy a new cap/gauge/float assembly for this particular
tank, but that would only solve the problem for a while until that float
gets heavier.
I wonder if I can paint some sort of material on the float to make it
more resistant to permeation of the gas?
I know the material has to be non-soluble in gasoline.
Ideas??


Pretty much have to buy a new cap. If gas has already soaked into the
float, then no type of sealer is going to stick. Even if it did, it
would weigh down the float and give you a wrong reading, which is the
problem you are trying to solve. I dont see too many of theese type of
floats go bad, but it does happen, and no type of repair or jerry
rigging will fix it properly. Good Luck....Todd, Owner, Nuevo Lawn and
