Running your vehicles fuel low below 1/4 tank consistently will expedite (speed up) your vehicles fuel pump to fail!!
The fuel in the tank is the ONLY cooling the Electric fuel pump has. Running your fuel low exposes the expensive fuel pump and without cooling the pump overheats and fails. Some newer in tank pump jobs easily can be $1000+
Simply keep your fuel above 1/2-3/4 tank all the time and you could extend the life of your cars fuel pump.
