What causes the fuel dispenser to dispense fuel with the nozzle pulled up? A related investigation on the oil and gas recovery side

The issue of "gun-carrying and meter-running" can be divided into two categories: fixed value and continuous. The root causes often lie in the rubber hose of the fuel dispenser's foot valve and the breather valve. A continuous meter-running issue can also arise from a leaky connection between the oil and gas circuits on the recovery side. This article clarifies the mechanisms and troubleshooting methods for both categories.
