[Fot] Leaky SU floats...

Years ago when Ethanol was first used in gasoline in the Midwest, I saw
a large number of lead soldered brass floats (carb and fuel sender) sink
due to the acid from the ethanol eating the flux that was used and thus
leaving a weak spot in the joint that the fuel could eventually migrate
through. Now that ethanol is in everything ( pump signs may not say it
but more than likely it is in all gasoline from 5 to 15 % or E 85%) due
to it's cheap octane boosting capacity it may come back to attack these
old brass floats. I have successfully used a fuel resistant epoxy to do
the sealing like Bob Wismer, since most of my old stash has been
consumed by this.

Periodic update on leaky SU floats perceived to be the result of
additives used currently in racing gas.

My racing partner, Bob Wismer, has treated several repaired SU floats
with POR-15, the rust preventative product often used to repair,
restore, and seal fuel tanks.  The treatment was no more sophisticated
than dipping each end of the float in the product.  While this does not
seal the center seam, it does appear to seal both tube ends, where the
leaks in our floats have occurred.  We've since been through two events,
without a failure.  We are very encouraged by this, and pass it along
for what it is worth.
