Adapt EFI Fuel Hardline Connections to AN

These adapters provide a direct transition from a compatible male EFI fuel hardline connector to an AN connection. The adapter has a male AN connection at one end and a female SAE-style EFI quick-connect at the other.

Female EFI Hardline Connection

The female EFI connection fits over a compatible male fuel hardline connector and secures behind its retaining feature. This allows a compatible existing fuel connection to be retained without cutting or flaring the hardline.

JIC 37° AN Connection

The opposite end uses a male AN connection with a JIC 37° cone flare for connection to a compatible female AN fitting.

6061-T6 Aluminium Construction

The adapters are manufactured from 6061-T6 aluminium with a black anodised finish.
