π’β½ FUEL PUMP HANGER UPDATE β½π’
Going forward, the 3000GT/Stealth Stainless Steel Fuel Pump Hangers will be transitioning from PTFE-insulated wire to ETFE-insulated wire.
The cost of genuine PTFE wire has increased significantly, and continuing to use it would unnecessarily raise the price of the completed fuel pump hangers. Switching to ETFE allows us to maintain a high-quality, durable product without passing those additional costs on to our customers.
β οΈ To be clear: ETFE is not ordinary automotive wire, and this change is not a downgrade. β οΈ
The wire being used is SAE AS22759/16 mil-spec ETFE wireβa high-performance fluoropolymer-insulated wire commonly used in demanding aerospace, military, motorsports and industrial applications .
β
600-volt rating
β
Temperature rating of -85Β°F to 302Β°F
β
Excellent resistance to heat π₯
β
Excellent abrasion resistance π‘οΈ
β
Resistant to hydrocarbons, oils and alcohols β½π’οΈ
β
Mechanically tougher than PTFE insulation πͺ
β
Manufactured and tested to SAE AS22759 requirements π
π§ͺ Under the applicable AS22759 immersion testing requirements, the insulation must meet the following standards:
πΉ No more than a 5% increase in insulation diameter
πΉ No cracking after testing
πΉ No dielectric breakdown
πΉ Continued electrical insulation integrity β‘
β½ ETFE has excellent chemical resistance to hydrocarbons and alcohols found in gasoline and ethanol-blended fuels. The selected wire is suitable for the demanding environment inside our fuel pump hanger assemblies, including applications using gasoline, E85 and commonly used race fuels. ποΈπ¨
π© The stainless steel hanger design is not changing.
β‘ The electrical operation is not changing.
π The fitment is not changing.
π Only the wire-insulation material is being updated.
This change allows us to continue producing a reliable, high-quality fuel pump hanger without unnecessarily increasing the price due solely to the rising cost of PTFE wire. ππΊπΈ
