S.S. Fuel Line Replacement by Clay ?????, My math may be screwed up here Options

[914forme]

I have been reading and gathering the items to replace my plastic lines with SS, my plastics are real bad.

So I read Clay's nice documentation on how to do this. I get me some nice pieces of SS tubing today, come home. Look at my stuff and go DOAH!

Clay calls for 7/16" line for the main pressure loop and return loop. So I am wondering if the number got messed up.

I grab my calipers and start measuring

Fuel log, pump, and pressure regulators = .3271 okay this is about 8-mm makes good sense now.
3/8" line = .3750
7/16" line = .4375

So it looks to me I should have bought a few sticks of 5/16" line which is .3125 or 21/64s (yeah right) which is .2813

Or am I just smoking crack here (IMG:http://www.914world.com/bbs2/html/emoticons/screwy.gif) and this will work?
Or maybe all 3/8" line and make the hose stretch just a little.

Just wondering Clay is a great guy just thinkin I may be nuts.

Here's what I would use: If your fuel pump is in the front, use 5/16" for deliery and return. If your fuel pump is in the back, use 3/8" for delivery, and your choice of 3/8" or 5/16" for return. The smaller the line, the easier it will be to bend and route the lines. Going to 7/16" you will have much more difficulties bending and routing the lines and you will have problems fitting them through the stock grommets (especially important with the front grommet).

I used 5/16" delivery and return lines for mine (and moved my pump to the front at the same time.
