Need help adapting my old fuel system...

..to my new carb.

I bought a new carb from Summit along with their adjustable feed line that has a built in filter and pressure gauge. I have the stock fuel pump with 5/16 hard line to the existing carb. I want to make a new hard line to connect to the feed line inlet which according the the specs is a 3/8-NPT female. What do I need to adapt that to 5/16 hard line? I've been searching but it doesn't seem to be very straight forward.

I think you just need to buy a new fuel pump for a four barrel, it will use a 3/8 line.

I had considered that but wouldnt I have the same problem in the fuel pump inlet side?
In any case I ended up scrounging around at the hardware store and found a 5/16 compression to 3/8 NPT adapter that did the trick.
