Technical Bulletin
Technical Background
The black in-tank fuel lines contain a material known as PA12. PA12 was not meant to be used with fuel
containing alcohol/methanol/ethanol. If PA12 fuel lines sit in fuel for over 3 day without driving and in
temperatures over 77° F (25° C) a chemical reaction occurs that creates small white crystals to form on the lines
(figure 1). These crystals can flake off into the fuel, gumming up the pumps and lines.

Figure 1
Note:
A reaction of the in-tank fuel line exterior will only occur one time, once the material has been removed,
the lines and system require no further repairs.

Production Solution
Fuel lines made without PA12 to be placed into production.
