Ethanol and my gas gauge

Absolutely beautiful day today. Thought I'd dig out the coupe and put a few miles on it. Got it out of the garage and glanced at the gas gauge. It said 0, not 1/2, where I left it. Put a couple gallons in it, still 0. I installed a gas gauge kit from Macs almost exactly 1 year ago with the improved neoprene float that won't sink. Well, mine did. The original cork float sunk, the all new improved one sunk. I know it's the ethanol. Does anyone know of another float? Can I just put in some mystery oil and wait for the float to pop back up?? :)
 
Are you sure the float has sunk? with those new floats you have to get creative to make some kind of retainer to hold them.I've looked at a couple where the owners have had the same complaint,and both times the new float had come off the wire.
 
I will double check as soon as I can. While we were driving it, the fuel gauge kept bobbing from 0-3/4 full. I looked in there when we got back. It just looked like everything was on the bottom. I don't mind having a hobby, fixing the gas gauge yearly ain't what I had in mind! Thanks
 
You got me thinking. So I went out and checked. Yup... There's my float, still attached, sitting on the bottom just like the titanic. So much for "improved". Maybe us poor NY folks are really getting E25 instead of E10 gas. I just knew things were going too good. Car fired right up, purred like a kitten. Back to the wooden ruler for now, I guess. :o

Check in the archives some people solder a brass carburetor float on the end . Ya know gas is not going to eat that up.
 
Did you buy the kit that comes with the gauge assy
What is the part number? Some of their floats are not ethanol proof

Mitch, I bought the rebuild/gasket kit, #28-24797-1. Almost exactly a year ago. Bogart, I was thinking that same thing, brass float. Thanks
 
I know Ethanol is always a favorite target here on the barn but I have never had any issue with running it for the last 10 years. I replaced my cork float or what was left of it years ago with the neoprene float that appears to be in your tank and it is still bobbing away. If I would change the float today I would go with the brass float for sure.
 
I've fixed sinking floats both in the tank and in the carb by dipping them in tank sealer (after letting them dry out). If the sealer will keep the fuel in, it will keep it out.:D

I think that you are right about the brass being safe from Ethanol ... at least for now!!






My money says the next problem will be that they will come up with some crap "gas" that eats up the steel wire that fastens the float to the gauge!! :D:D:D
 
I put a new cork float in my tank in 1995 and it still works, even with several tanks of crap gas I had to use. I did spray a coat of something on the float before I installed it, but I don't remember if it was clear lacquer, varnish, or shellac.
 
I don't know what material Bert's uses, but Steve told me they researched it very thoroughly.
I have used theirs for about eight months with no problem.
 
Mike V. what is the float in your pic? I was looking for a brass replacement for the one that will slide on the float wire. The one on mine is not cork, it's the improved neoprene. The only other thing that could have caused it was stabil fuel stabilizer. I use it in everything over the winter.
 
The brass float in Mike's picture looks like the one a member of our club, San Diego Model A's makes, they work great! Also, any other brass float that fits through the gas gauge hole and soldered to the wire will work.
 
I bought my gas gauge parts from Bratton's and it has not sank in several years. Perhaps the place you got yours from does not have the same quality float.
 
the brass float cracked ---the cork float sunk, now I have a float salvaged from modern car, the new cars have the fuel pump/sender as 1 unit, i salvage floats from the old ones
 
For the Aussies, this is a float out of a commodore VP, but any float out of a modern car that will fit thru the hole will do.
