I'm planning to install a 1/2 inch line in my car when I install an electric pump. I've got -6 hose from my mechanical pump right now, just bought the hose and fuel filter last year. I don't really want to drop another $200 bucks for more stainless hose, fittings, and fuel filter.

Is there an easy way to adapt the 1/2 inch line to accept a -6 hose? I don't really need the 1/2 inch line but I don't want to go through the trouble of running a new line and use 3/8.
