I used 5/16" brake line from the Napa. Got a 48" length. It had inverted flare tubing ends. Cut one end off, used the fitting with an adapter to attach to carb. Bent it with a handheld tubing bender tool to run forward over the intake runners, around the driver's side of distributor (big block), in front of distributor, and down to the pump (it has a vapor separator, but no matter). Fairly easy to bend, warmed it up a little to avoid kinks, looks factory, soory no pics as I'm out of town.

If you put a filter between pump and carb, might have to make some homebrewed or (if you can find them) factory-looking standoffs from the intake bolts or coil bracket bolt holes to add in the hose to tubing connections and keep the tubing in one place on top of the engine. I had to that when I later added the pressure regulator.

Also, wrapped the tubing in hose that I slit length-wise to aid in insulation from engine heat.

If I get some pics of it later this week, I'll post 'em.
