HIF carb floats

Anyone have any experience with the `Stay up` carb floats for the HIF6 carburettors ?

The original SU ones are getting a bit thin on the ground so I have ordered one and awaiting its delivery.

Perhaps we can get the Viagra jokes out of the way first

Ta!

Yep got them in mine after one old float filled with petrol. They’re better than original as they don’t absorb modern petrol. Make sure you get float height bang on it’s important.

Just fitted it and seems ok so far.
Checking the old one out that was almost completely full with fuel I could find no leak. Even to the point of putting powder on it and leaving for a few days, how does that happen?
Anyway will see how it goes

Did mine about a year ago and float is still full of petrol. Think it must be osmosis.

I wonder if they only open up a bit when hot. Makes sense, float warms up, microscopic crack opens, air inside float expands with heat, then air cools and sucks fuel back in through the crack. float cools and crack closes up again. it would be worth trying under a vacuum to see if the fuel leaks out again. Or place in a pan of hot water and see if the float bubbles.
