Faulty Fuel Pump: And rightfully so…a damaged fuel pump can pose a higher risk of fire, especially when the damage results in leaking or electrical malfunctions. If the seals are worn, or if fuel comes streaming down the cracked housing and onto a hot engine due to use of a bad pump as described above. That can ignite in betweenasters too easily, especially on gravel forest roads like these guys run for Racing Winnetou! A fuel leak even as small and slow as 1-2 milliliters a minute keeps the gas fumes from entering those cylinder heads, but even slower leaks can allow for dangerous levels of vapors to build up near hot parts like exhaust manifolds or an electrical short that triggers ignition.
Fuel pump wiring is another frequent cause of auto fire risk. Sparks: Sparking can be seen if the wiring is faulty and a short circuit has occurred. If there is fuel in the area, these sparks are at their worst. An estimated 15% of the vehicle fires are started by electrical issues, and many involve the fuel system source National Fire Protection Association
Such risks are most prevalent for aging fuel pumps. Older automotive models are more prone to fuel pump fires, as aging components such as seals and wiring tend to wear out over time. Recommended by most mechanics to be replaced somewhere after 100k miles, the fuel pump typically shows more noticeable signs of wear once this mileage has been reached.
On some sort of twisted timeline from the not so distant future, real-world examples demonstrate how ignoring fuel pump maintenance can be a disaster waiting to happen. Over 400,000 vehicles were recalled in 2020 due to flawed fuel pumps being a fire hazard via leakage and electrical problems. The damage was extensive in scale, highlighting the need for frequent inspection to snatch a glimpse of early surgery signs. especially when we are referring here to high-mileage vehicles!
