Fuel Feed Line Size

Is the factory fuel feed line (metal tube) that goes from the tank to the rail 3/8" OD?

No, the OEM size is not 3/8" ID. The size is likely 10mm in ID. 3/8" is approximately 9.525mm. I realize metric hose is hard to come by at a parts store. 3/8" fuel line will likely do the job you need it to do if you are looking at repairing a fuel line.

So what would be the best way to adapt a fitting to the stock fuel line? I was thinking of just double flaring the stock line and using an -6 to 3/8" tube adapter fitting. Would this work?
