Gas Gauge suddenly reading backwards

Have you crossed the equator recently?

Your float has a hole in it.

Wouldn’t that just make it read E all the time?

Bizarro world indeed.

My gauge used to read backwards, but it always did. I bought a new one and bent the float so it reads correctly.

My pea-brain can’t comprehend  how it could suddenly switch.

Is this viral marketing for the new season of Stranger Things that comes out this week?   The preview has the kids exploring the upside-down world.

I still have 4 forward gears and 1 reverse, so that's a relief.

@dlearl476 you may be right I’m just throwing out some Idea’s

@Panhandle Bob yeah but are they in the same pattern as they use to be? The way things are today nothing seems to crazy! Lol

But you posted this in the Spyder section, so there's that. Bizarro world indeed!

New govt plan to get you off using gas:  You think tank is full.  Head out for nice drive and have to walk miles back thru Freeport in the hot FL sun.  Wife says last time I'm getting in that polluting thing, we take the Tesla next time!

Guess electric ground and float are my guesses.  I guess the float arm could be wonky/broke/loose?

Try driving it in reverse for a few day and see if that fixes it.

probably need to bend sender rod a few times..my 60 VW in Navy didnt have gas gauge,,best is to figure out average mileage X gallons,,i think i used 120 miles as a safe point..

Is your gas gauge at the bottom of the multi-gauge with temp at the top?

If so, is it showing temp OK?

I’m not yet convinced that it is a bad gas sender.

My car is so easy to push, I wouldn't mind if I had 5 forward gears and NO reverse.

It's possible the wiring to the sender in the frunk is frayed or loose, causing intermittent readings that might seem bizarro.

Inspect the wires in the frunk carefully - especially on the under side you can't see. Anything metal rolling around in there that might be touching the contacts?

Also, in my car the wires pass through the firewall through a small hole in the fiberglass not protected by a rubber grommet - another possible point for abrasion and shorting.

If you've really found a way to fill the tank without actually buying gas, please share with the group.

The explanation for my instrument weirdness was that my wiper switch is a headlight switch. Good so far although surprising at first discovery; does everything a wiper switch should do. Only problem was that the gauge lights brightness connector on the wiper switch was also wired, so if you turned (rather than pulled) the wiper knob, you were varying something back there from 0 to 12v. Have you twisted your wiper knob recently?

Or are your gas gauge contacts exposed in the frunk where something could short across them?

@Panhandle Bob

So what's da scoop?  Did you try grounding the sender wire to see which way the gauge needle went?

Haven't touched the car in the last few days. Incessant rain has kept it in the garage and business has kept me away from it.

My guess would be a bad tank ground or the sending unit is bad.
