Fuel level sensor By blu (Read 1,226 times)

My fuel gauge hasn't worked since I got this.  Yesterday I removed the sensor, and it works find and the level reader in the dash works fine.  But as soon as I install it in the tank, it reads empty.  I took it out time and time again, works fine, but in the tank, not.  Checked the float, float floats like it should.  Something is obstructing the float in the tank.  I swung the unit back and forth from one side to the other and left in in the middle of the swing.  I have half a tank, and at least now it reads one notch above empty.  I'll take it out today and fill it and see what happens.  But is there a trick to this?  There doesn't appear to be any indicator as to where it in supposed to be positioned.  I'm glad everything works, I just need it to do it's job.

When you hook it to power out of the bike do you use the original sending wire then ground it?,,,,tank may have a bad ground issue

Wonder if it works until the body of the sender touches the tank. Shouldn't be any big deal to sort out. Some of them the float rubs on sides of tank and then there's the ones that the float don't float!

There is a rubber seal between the sender and the tank, no contact. The snder works when it's in the tank, it's just showing reserve. Once in a while it will read one notch above, but goes back down. I am totally convinced the sender is working properly, I just have to figure out how to feed it in there. There is a tube running lengthwise in the tank, not sure of the purpose, maybe to prevent splash, but I'm thinking I feed the float in to the wrong side of it. I need to look up the sender online and see if it's the right one, I'm sure it is but I want to verify.

Ok, the float floats in water, sinks in gas. Guess I had a lesson in buoyancy. Anyway to revitalize my water-logged float?

Yep you need to get it dry,,,and reseal with the same material they coat badly rusted tanks with but thinly so it doesn't add a ton of weight or replace it

[blu]

I figure I'll drill a couple holes to drain it and seal the holes and the ends with gas proof sealant, they should have that crap at an auto parts store, right?

Be nice to find where the tank leaks at before blindly sealing all of it. I take it the tank is plastic. I have tried sealing a brass one by soldering up a crack but it did not hold very long before it leaked again. might be time to just replace too.

None of the pics I've seen of fuel level senders looks like mine. I'm sure I could make one work as long it fits the hole right. I'll send these guys a request and see if they have one.

If you're inventive you just may be able to make a hybrid,,,using the original sending unit with a new float and arm

[blu]

That's what I'm thinking, even cork if I can find a suitable sealer. I'll stop at the auto parts store today and see what I can dig up.

Found a used sender in town, $20! Highway robbery. I just put the float on mine because the senders were a little different. It floats. Now I just need to do a little adjustment to get it to reflect actual fuel level. Never thought finding a float would be so difficult.

Good dog,,, an extra bone in your bowl tonite,,,,the trials and tribulations of owning a scooter,,,,,,,after you get it adjusted it'll be more accurate than the stocker,,,,of that I am curtain

Adjusted the float today. Perfect! Well, as perfect as a gauge can be. I'm a happy camper

Nice!!!!! There's a piston right there!!!!
