fuel hose measurements

I searched the forum, and I found some information, but not this exact information that I'm looking for.

Can anyone verify or correct me if I'm wrong? I'm trying to replace all the rubber lines on my fuel system and a couple of the vacuum lines.

What I have measured using a caliper:

filler neck hose: 1-3/8" ID, about 12" long (with OE curved inlet neck).

big vent line that goes up by the filler neck: 1/2" ID, about 36" long.

all smaller vents (to include the two coming off each side of the tank, that go to the rear where three vent lines go up at the rear corner of the bed): 5/16" ID, 65" all told.

hose from sending unit to the metal line on the frame: 5/16" ID, about 12" to 13" long.

hose from the metal line to the fuel pump: I measured 3/8" ID, but it seems like it should also be 5/16", so maybe I didn't get my caliper straight, and 5.5" long.

vacuum hose from the intake to the brake booster: 3/8" ID, 18.25" long.

vacuum hose from the carb to the valve cover: 3/8" ID, 10.25" long.

vacuum hose from the carb to the distributor timing advance: 1/6" ID, 18" long.

Thanks in advance for any info!
