Do fuel tanks cross feed and equalize?

Ohh cmon, we know you broke it off... let’s us in... How’d you break the nozzle off...

But yes, equalization will happen.
If fuel is super high I get one tank or say 50-75 gallon to get to a place to get it a bit cheaper.

 

It May Equalize....as stated above.....unless the crossover Line is SHUT OFF.....IF It HAS A crossover Line.
Some Trucks Do Not For Whatever Reason.
Oh, and Fuel Gauge Is Correct Twice: FULL & empty.

Some of the Remaining Older Truck Stops Have LONG HOSES.

 

I Liked Seeing Road tractors Like the Picture. Even More Hilarious On SIGHT SIDE!!

 

Literally: “this bisch empty. YEET”

 

Your truck will stop running when either fuel tank runs dry. That's to say you stop when the first tank is empty.

 

My ol truck drew from the driver side tank back when fuel lines ran side to side from the bottom of the tanks. I was off exploring back roads bypassing the POE in a state that I was not supposed to be in. Thankfully I made it back into Texas and was on some long straight roads with long sight distances and I was intermittently able to drive on the wrong side of the road for a long enough time to get most of my fuel to move over. I then stopped and shut the valve on the bottom of the passenger side tank. Needless to say, I never put myself in that position again.

 

I Used A Rubber Strap With 2 Hooks To "set" The Fuel Handle In The Tank Neck.
Secure Method.

 

It all depends upon what truck, exactly, you're talking about. Not all are the same. But in most cases if you let one tank run dry without shutting it off your truck will start sucking air and will not run.

Many trucks will equalize due to gravity, but not all will. Others will only equalize when the truck is running and the tank with less is getting more fuel via the return lines from the electronic fuel system than the other tank.

It all depends on how the specific truck in question is set up.

 

My thoughts exactly, our older Mack's would equalize in a matter of minutes, whether running or not, these new KW's can take hours to equalize, and I've crossed my fingers a couple times
