Multiple Choice

With low fuel contents fuel pressure will _______?

Explanation:
With low fuel contents, fuel pressure tends to fluctuate because the pump and lines contend with changing suction conditions and potential air pockets. As the tank holds less liquid, small movements of the fuel or air pockets near the pickup cause the pump to pull varying amounts of liquid and air, leading to alternating periods of higher and lower pressure downstream. The engine’s demand can amplify these pulsations, so the pressure doesn’t stay constant or steadily rise or fall; it varies with the flow situation.
