Industrial/Marine 12v injector return line fitting?

[getblown5.9]

Anyone using the marine style 12v injector return that goes behind the valve cover know what fitting is on the end of it? its some type of flare with a thick rubber washer to seal it.

I cut the end off and used a -4 tube fitting to go to AN hose.

The original fitting is basically a compression fitting done with a rubber ferrule, cummins loves that style fitting for some reason...
