Does it hurt to run with just one fuel tank

I have two 150 gal fuel tanks. the tank on the passenger side either has a broke pickup line inside the tank or return pipe.

I shut off the valves for the second tank about 3 months ago and actually like just running on the single 150 gal tank.

Is there any performance hits I am taking because I only run on one tank.

there's no adverse effects from running on just one tank. you are also lighter by about 1000lbs running only 150 instead of 300 gallons of fuel. what was the problem with your pass side tank?

Fuel pickup or return and cross over didn't balance the tanks well.

i've had that problem and it turned out to be clogged breather tubes.

I had that problem and found out it was one of the rubber draw lines was collapsed. Volvo uses plastic air lines for fuel lines and works good. But not when they have been cut and spliced with a rubber fuel line. That rubber fuel line swelled and collapsed and drew all the fuel out of one tank and filled the other.

only downside to running one tank is that the fuel may have a tendency to get hot.

I disconnected my passenger side tank and only run on the drivers side tank. As a result, I fuel daily which allows me to more closely monitor my fuel milage, keeps the fuel fresh and its easier when adding additives.
