that depends on size of engine
It depends on the truck ie;a volvo 780 burns 7.0 gallons in 10 hrs.
Effectively all the fuel that it burns while idling. You are getting 0 miles per gallon while idling.
It could take an estimated 1/2 gallon to 1 gallon idling for a hour.
4.7 liter per/hour
a lot more than needed to use
It is in the line under the truck about midway to the engine.
There can be many reasons why a car surges while idling. Some of these reasons are the computer could be dying, or the fuel injector are giving the engine too much gas.
none it runs from the sun
150 pounds....
Too high of an idle could be producing too much fuel for your jets to work with
it idles quickly to save as much fuel, energy, oil, etc. as possible
If its carbureted might be forcing to much fuel flooding out
