Fuel Inlet Neck interface

[rick8928]

What is Factory Five's recommended approach for interfacing a late model Mustang (e.g. '04 Mach 1) fuel filler neck with the Aston LeMans gas cap? The stock neck has a 1 3/8" OD at the tank, 1" OD in the middle, and 2 2/8" OD at the top. There are some posts at ffcars.com on this, but am looking for the factory's input (and it would be cool to see a FAQ on this). Thanks.

Call the factory tomorrow, we have a 1" filler neck hose that can attach to the late model filler neck going into the tank that can be used as an adapter with the larger 2" filler neck hose going over it up on to the aston cap.

Jesper,
Awesome! A response from the factory's chief engineer, within 24 hours, and on a Sunday to boot! "I think this is the beginning of a beautiful friendship."
