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.

SS line is easy to pickup local you just have to step outside the automotive world and into the industrial hose and fitting world.

Look for a Parker Hose and Fitting place - they will have pretty much any connector you may need. I have found one exception to that M12x1.5 to -6an. They have hoses to do anything you want form low pressure to high, flame resistant, oil, air, water, various braids etc.... And you can get quick disconnects also. If you want to deal local these places are great. Mine has a great counter guy that likes doing my odd ball stuff, he gets a kick out of it. My guess I break up the rhythm of his day. A good change of pace for him, I just take in all the parts I am dealing with or know the pieces thread size.
