1. CPE Fuel Lines & Ethanol Compatibility:

   • CPE (Chlorinated Polyethylene) fuel lines are recommended for use with fuels containing up to 85% ethanol (E85). This is important because ethanol, especially in higher concentrations, can be more corrosive and may degrade materials that aren't designed to handle it. CPE is a material that can handle this level of ethanol without deteriorating quickly.
   • For fuels with more than 85% ethanol, it would be important to consult the manufacturer of the fuel lines to ensure compatibility, as higher concentrations of ethanol can be more aggressive on materials.

2. Importance of Cycling the Fuel System:

   • Dry Rot Prevention: E85 ethanol can be corrosive, especially if fuel lines are left empty for long periods. Cycling the fuel system once a month by driving the car (or running the engine) ensures that the ethanol remains in the lines, keeping them hydrated and preventing them from drying out. This helps avoid issues like cracking or dry rot of the fuel lines, which can lead to leaks or fuel system failure.
   • For vehicles that are not driven often, ensuring the fuel lines are regularly exposed to fuel and not left dry is essential for the longevity of the system.

This recommendation is part of regular car maintenance for E85 vehicles to ensure safe operation and extend the lifespan of the fuel system.
