Can Low Fuel Cause Pump Damage
Fuel-starvation can hurt the pump as it needs both of these to run cool and lubed. This pump operates under high speeds and requires a cool liquid medium to prevent overheating, the fuel in the tank works as a cooling hydraulic for the pump. Under a quarter tank the pump can start sucking in air going away it’s capacity to keep consistent pressure normally 30-60 psi on most vehicles. Increased strain can cut the pump’s lifespan by 20 percent, which allows wear to happen earlier, resulting in possible pump failure.
When low on fuel, the pump will be able to suck in particles of debris and sediment that settle at the bottom of fuel tanks. This sediment clogging causes the pump to have to work harder than usual in order to push fuel to the required pressure. According to mechanics, debris associated clogging is attributed to almost 15% of fuel pump failures; particularly in aging vehicles with high mileages. Maintaining a quarter-tank level minimizes the risk of sediment injury, thus prolonging the life of the pump.
Constant low-fuel operation is not only hard on the fuel pump, but also hampers overall fuel economy. Researches show the fuel economy is up to 10% less efficient on vehicles with low driving on gasoline, as the pump has already had to over-compensate for inconsistent filling levels The continuous strain on the fuel pump results in lack of power under load, exacerbated fuel economy, and even lean stalling during acceleration or climbing a grade.
The law to follow for refuelling, according to the experienced automotive experts: Fill up when the tank drops below a quarter full. According to John Nielsen, an AAA spokesperson and veteran of the automotive industry since 1981, “maintaining a quarter-full fuel tank helps to cool the electric pump and keep it submerged in fuel. This safety feature reduces the chances of burning out the pump from over heating.
Being proactive with keeping the fuel tank full is good not only for protecting the high-pressure pump, but will further assist in preventing any performance or reliability issues.
