Engine upgrades-Fuel questions

[HOTY65]

I'm sure this has probably been asked/discussed many times before, so please pardon me if repeating an old question.

I'm wrapping up the refresh/rebuild of my 72 Grande - 351C-2V. No block or head internal mods from stock. I did decide to upgrade to an Edelbrock Performer 2750 intake matched to a Holley Street Avenger 670 carb.
I've waited a very long time to get this car and to get the engine torn down and gone through and have no real intentions of pushing it, just easy cruising with the occasional romping for fun.
Question: The stock fuel line from the pump-to-carb appears to be 1/4" (or maybe 5/16"), but the Holley fuel filter and carb are 3/8". I'm curious how you guys adapted up the fuel line.
My engine won't likely see many high RPM runs, so I'm not overly concerned in high-capacity fuel/flow upgrades being needed.

Thanks

Either find an inline fuel filter with a 5/16" inlet and 3/8" outlet, buy a carb feed line you can fit a 5/16" nipple on the inlet, or stretch the 5/16" fuel hose over the 3/8" nipple. Use fuel injection hose clamps rather than the worm gear style.. Fuel injection hose clamps apply even pressure around the circumference of the hose and won't cut into the hose.
