The little ball that's attached to the fuel gauge sender in my car has a hole in it meaning that the fuel gauge isn't working. It is not possible to buy a replacement float - the whole sender unit must be purchased, which is expensive.
Would something like a fishing float or cork or even a table tennis ball survive being inside a fuel tank?
I used a pill bottle. Standard hole for sending unit is 1 1/2", pill bottle is 1 3/8". grind the most outer part of the cap off and cap retainers on the bottle. Epoxy glue the cap to bottle. I drilled holes in each end and Epoxied to lever rod. I then put a whole coat of epoxy over entire bottle. The epoxy fully encapsulated the pill bottle. 5 minute epoxy at the Dollar Store $1.99
I have a 1999 for f250 super duty 7.3l doesel engine with a 38 gallon tank, my old fuel float was made out of pvc and it lasted for 20 years and eventually eroded i just got a cheap pieace of 1×2 pvc board from home depot cut it to size, drilled a whole and got a new working one for 4 dollars. Not a bad method its cheap works great and easy to do. I hope this helps any of you for me i called tons of stores and suppliers and couldnt find anything like what i needed.
