fuel flows to one tank overnight

Parked at 1/2 and 1/2, how much more will be in the pass tank overnight?

 

are you parking on a hill?

 

Not uncommon in my area in very cold conditions. And ya it sucks running out of fuel from the feed tank while the other tank is trying to push fuel through the filler cap

 

Any idea why my nine button displays and toggling through it just stuck on KM and that’s all I can do. I replaced the nine button with a brand new one, but it still doesn’t read. I thought it was maybe bad any help would be grateful thank you

also my fuel guage does not work replaced the sending unit doesn’t do anything sometimes stays at half to 3/4 or down to a fourth but never accurate

 

You commented on someone else's post about their truck problems, with a ? about your problems.

You should start your own post about your specific fuel sensor issues to get an answer, because at this point, people won't comment because they think your problems are the OP (original posters) problems.
