Fuel Float Delima

Post by Southern Style »

OK... What I am trying to do is find something like a glass bead that I can place in the sight tube on the side of the gas tank making it easier to judge fuel levels at a glance.. It would be easier than trying to find a clear line of fuel in a clear tube at a glance while driving.. I know, they make fuel gauges... Im not interested in one. Just trying to find out what would be a good visual float to use. Plastic?? Maybe like the beads on those leaders used for fishing?? What would work and not be dissolved by the 100LL..

Thanks for any help..

Chive On..

is your tank cut for a regular fuel sender ? if so they make a mechanical sender that has a magnet drive needle on top. old makos used to use these alot .just an idea , if you going with a site tube maybe like a necklace bead might work

Gas tank is not cut for the old style gauge in the screw cap type... But with the straw on the side, It would be nice to find a RED bead that would float at the top of the fuel level inside the clear sight tube... Might have to just take a RED bead and let is soak in 100LL for a month and see if it disintegrates or bleaches out or just dissolves... That's my fear. Coming back and find it in a powder floating in the bottom of my gas tank.. Might have to fly by trial and error ( in a controlled environment of course)

They make a mechanical unit that is a direct fit for replacement where the electric sender fits. It uses a float and a gear drive to move the needle. I have done it, if you can't find one locally Alumitec sells them. The old clear tubes don't hold up with this crap fuel. Talk about dangerous YIKES

Run nothing but Avgas and only thing I have ever had happen was after 3-4 years, the tube starts to discolor a bit. I just replace it with another 50 cent piece of hose. My boat also has a front seat driver, so seeing that gauge on top of the gas tank that far back and trying to see what it reads might take longer.. LOL... Site tube has always been perfect for me, just seeing if there was something that would be more of a contrast in the tube for me to glance at..

Thanks for that info though.. Its a 25 gal tank, unknown if that arm would reach all the way down to the bottom..

Will do Tony... Gonna get with QuickDiesel.. He deals with fuel and carbs every day!! He might know. Then Im gonna hit the stores and see what I can find out.. Will keep u posted..

SS what is the inner diameter of your sight tube? Not sure if a 10mm, 3/8" is to big, but may point you in the right direction! :rebel:

you could make some adapters to increase the tube size so the float is bigger than the inlet and outlet tubing so the float will stay in the tube.
then all you need is the float and design to it.

Michael's Crafts has thin brass tubing and brass sheet. just cut a short piece of tubing and solder some end caps on it. It should float. Or just crimp the ends and solder and file to fit the sight glass. Ace should have it too, or use a piece of a brass arm off an old lamp. Needs to be thin though. I used to have some around here somewhere, If I find it Ill crimp and solder and float test a piece. Pretty sure copper is too heavy for this way.

If ya find a bead thats ok but is small enough to drop into the tank, cut a small disk of faucet nozzle screen and put in each end of the sight glass. Same size as ID of sight glass but larger than the 90 degree fitting on the tank.

Awsome ideas guys!!! I am gonna measure the inside of the cleat hose. I think its 1/2 in clear hose.. if those hollow ballsndont work, might try the glass idea. Dont think it would pass the 90 degree elbows. Think it would stay in the clear tubing. The brass idea is awsome but cant solder worth a crap.. lol... will get goin on these ideas and let u know.. thanks for all the ideas..

We sell these guys sight glasses, and they show a "reflective ball" (suffix rb) type. Dunno if it`s what you`re talking about, but it`s what I thought about when I read your post.

Has been, I tried page 22 but found nothing that would float in gas and not dissolve.. Did I look in the wrong place? Hit Ace on 192, and we had a hell of a time. Thought about anything that was made for carbs, lawn mowers, bearings, even actual gas cans. Those don't dissolve in gas.. LOL... Keep being told to go to Michaels or a Bead place.. Gotta find something. I am gonna call that place kwanj posted. See if I can get something... This is crazy. Why is it so difficult to find something that will float in gas in a bead form?? LOL.. I feel like there are hidden cameras laughing at me cause I am missing something.. Gonna try a bead..

Thanks Junker... I know for a fact that I am NOT a mixologist, a chemist, and can not read them manufacturers data sheets that come with items as far as the make up of components.. LOL... The wife said to just research what will not degrade in fuel and find something of that material.. Easier said than done.. LOL... The search continues......

WOW, wish I had a major motor issue, it could have been diagnosed and fixed by now.. LOL..

High Density Poly Ethylene - HDPE is what your basic fuel cans are made of........pellets of it are sold by the ton...
I did see where they sell hollow glass beads on line though.

You could get a black plastic carb float and cut a piece out of it to fit in the line, they are usually pretty fuel resistant :).

Thats what Wade said... most stuff in fuel tanks are that cork stuff.... been busy with the Dep. Pill homicide trial so have not really had a chance this week to shop. Next week we should be done testifying so I can get back to the float issue...

We use a fuel line float on the whirlybirds.
California Power Systems has them.
Lockwood Aviation has them.
Bear Perkins has them.
They are red plastic 'pellets'.
