[ATTACH=CONFIG]541150[/ATTACH][ATTACH=CONFIG]541151[/ATTACH] I recently replaced my pick-up with a stainless tube with an I.D. of .48 which is just about the same as the I.D. of -10 line. When I hear people talk about 3/8" or 1/2" fuel line I often wonder if they are talking about I.D. or O.D. I always thought -10 line was 5/8" I.D. but everything I have purchased for my set-up in a -10 size measures approx. .48" I.D.

The fitting pictured above is a 3/8 npt to a -10 male. It is a stainless fitting. I machined out the I.D. on the 3/8 npt side to match the -10 side. Then tig welded the .48 I.D. tube onto it. Screws right in with no modifications to the tank. It is pictured next to my original pick-up for comparisons sake. I got the idea from some of Eddie Young's posts on here.

Rubber line comes in many different OD's. MArine is typically a lot larger OD for the same ID.
Yeh, -10 typically is close to 1/2" ID.

I thought I red somewhere that the AN numbers roughly correspond to 1/16 inch - i.e., -6 is 6/16 or 0.375, -8 is 0.500, #10 is 0.625, etc.

Better use a air drill and not a cordless or electric.

Hadley, that is pretty much what I was planning to do - straight nipple and then a sweeping 90. Did you go with braided lines or something else? I'm thinking that -8 AN should be big enough for my build.

I also thought the AN numbers corresponded to a 1/16 ". I guess not!
