- Hheidi10Aug 9, 2025
If there's no fuel delivery to the Valeo Heater, check the fuel delivery to the heater. Possible causes include an empty fuel tank; bent, closed, clogged, or leaking lines; paraffin deposits or frozen water in fuel lines; a closed venting opening in the tank; mixed-up fuel lines; a contaminated fuel filter or screen in the pump; a defective fuel pump or coupling; or fuel lines that aren't vacuum-tight.
