Gas tank full shows 3/4 full

Recommended Posts

Thought it was a fluke when I filled up a week ago. Didnt think much of it until last night. Topped it off. Got in shower 3/4 full. Get back out. Topped of the tank til it over spilled.

 

Any ideas? It does go down normal like normal as far as I can tell. Gonna have a crack at it tonight or tomorrow morning. Wondering if anyones run into this?

Old car, sensors are nothing but a rudimental variable resistor, with just a sheet metal wiper running across some bare wire coils.

 

Maybe the wiper is worn out, or was bent.

Maybe the wire arm that the float attached to was bent.

Isn't the sender accessible from the trunk ?

 

Never mind, I'm giving you a reason not to drop the tank, and put in a better pump.

My old Datsun truck's sender failed after 45 years.

Bought one off eBay out of Thailand.

It failed within a month.

(and people wonder why I talk bad about ching-chong shit)

Been driving without, just topping the tank off every few days.

But soon to be fixed, found a genuine Nissan sensor on eBay.

This Mark II lets you “zoom” in on the fuel gauge. Toyota called it Scale Change and on the digital dash after pressing the button it would replace the entire fuel level gauge with the last 1/8th of the tank for precise cheap ass behavior.

Brian, my buddy's x6 with digital dash could also do the zoom thing.

 

Sucks they ditched it on the x7 digi dash
