Should the fuel tank get low on gas, it will dramatically compromise the life of your pump, as they rely not only upon a good amount of fluid to keep them cool while running but also act like lubrication for its operation. A diminished tank of gas means the pump is being surrounded and cooled by air instead than fuel, overestimating it to run a newspaper article. Research into the automobile space shows that running fuel pumps on very low gas can lead to up to 30% shorter life spans, again due to this additional thermal stress. For these pumps, fuel in this case is a cooling agent -- and without it the pump has trouble getting rid of heat which heats up all the moving parts inside wearing them out faster.
Low fuel also runs the risk of air getting into the fuel lines and this is what causes "fuel starvation" which strains that pump. This can cause pressure to fluctuate, and when you have an engine relying on 40-60 psi, even the slightest drop in pressure could result noticeably lower efficiency or worse. A fuel pump operating in such conditions has to work harder to maintain flow rates, eventually overheating and failing. Those pressure drops, particularly in high-performance vehicles that require a lot of precision from their fuel flow to make the absolute maximum power they can--a single technology preached by almost every modern automaker--can sap as much as 15 percent of an engine's peak bloss. Power loss on acceleration equates directly to jerkiness for ordinary driving smoothness.
The majority of technicians as well as automobile engineers advise driving your vehicle when there goes to least a sector container in it to prevent these troubles. A fuller tank also keeps moisture from the fuel system so there is less chance for condensation inside during the winter, which means that water getting in with your diesel will not happen. Fuel systems can appear out of tune, corrod lines and block filters provoking the pump. Cold does thicken fuel a bit, and it may require that the pump running low on stuff has to work harder for consistent flow. This makes the poor thing wear out even faster!
Preventive maintenance will keep the thing nice and fast, as automotive great Carroll Shelby once said. Based on his advice of keeping a vehicle over the 1/2 mark is seemingly fine advice and works well both for fuel pump longevity as also contributes to improved gas mileage and performance across multiple vehicles. By selecting a premium Fuel Pump and keeping an eye on your fuel level, you make driving that much more reliable as to never catch off guard by unexpected malfunctions or unnecessary repair costs, each factor of which helps maintain the integrity of your crucial systems.
