But fuel pumps do become clogged, often from debris, dirt or contaminants in the gas tank. After some time, this causes expansion of these particles and lessen fuel flows thus causing decreasing pressure of the fuel and less performance of engine. Symptoms of a clogged fuel pump may include hard starting, stalling, loss of power during acceleration. The necessary fuel pressure varies from vehicle to vehicle but in most gasoline engines the fuel pressure is somewhere between 35 and 65 psi, so if that drops off significantly due to a clog it can really affect an engine's efficiency.
Although the fuel filter is specially designed to keep out particles from getting past into the fuel pump, it can still become filled up or not replaced properly (usually needs to be replaced around every 20,000-40,000 miles), which can cause contaminants to bypass the filter and settle in the pump. The pump's components (inlet screen, fuel lines) could also accumulate debris if poor quality gasoline or a dirty fuel tank have been used.
A fouling fuel pump can also cause lean running, or when the air to-fuel ratio is too high, which results in misfires or possible engine damage as well. A 2020 auto repair analysis on automobile reveals that fuel system clog accounts for about 12% of the algorithm triggers to infarction due total failure of fuel system.
Fuel system cleaners are sometimes effective at dissolving moderate blockages in the pump or lines, but if it is completely blocked, deassemble it and carry out the cleaning of the pumping room. The cost to replace a fuel pump due to clogging can be as low as $100 or well over $500 depending on the make and model of your vehicle.
One component of a system — even the one that is part of just a subsystem — and if it doesn't work properly, throws off the whole show Musk believes. The same idea holds true for fuel pumps because perhaps a clogged pump is hurting the efficiency and lifespan of the entire engine.
Fuel pump clogs can be avoided by using good quality fuel and checking the fuel filter frequently, only requires replacement.
