Well, It seems this will be my year under the coach.... In a day or so, I will have the tanks defueled and down.
I want to put steel everywhere I can. Emery has suggested using brass compression fitting at the sending units.
Problem: Aren't there rolled barbs there to keep hoses on?
What does one do about those? I kind of hate to saw them off. I will if that is the good answer. I am not sure if I would rather that than use stubs of 30R9 to make the joint.
It is obvious that I will have to use 30R9 for parts of the system, I would just like to have those parts accessible for repairs that will be required later.
I am going to run double fill vents as far up as I can.

Matt,
Yes you are correct, there are rolled barbs on the fuel line fittings.
Here's a picture of the OEM fuel sending units:
http://www.gmcmhphotos.com/photos/403-port-fuel-injection/p9024.html
Hopefully the tubes on your senders won't be scratched like these!
When I had my tanks out down at JimB's I verified that after you cut off the rolled barbs there is enough tubing left for a
compression fitting, ferrule, and nut. I also verified that there was enough clearance between the two tubes to fit a compression
fitting. I was going to use a compression fitting to AN fitting at that point. That way if I ever needed to remove the senders I
could break the AN connection and not have to pull the tubes out of the compression fitting.
Unfortunately I was not prepared to install the steel lines at the time. Actually I'm glad I didn't as I will use Poly Armour when I
do it.
Here's a link to a picture of a new one on JimK's website:

It's hard to tell but it appears that there is enough tube left after you cut off the rolled barbs on these also. You might have to
"tweak" the tubes and spread them apart a bit though.
Regards,
Rob M.

Matt, while you have your sending units out, double check the ground coonection to the ribbon on the rheostats. They are secured with a small crimp washer that is notorious for loosening and then losing your fuel readings. When I had them out the second time, I soldered that connection. That will all makes sense when you see it.

Bob,
Thanks for the heads-up, but I am going to try to avoid pulling the sending units as I have done that once. Most of what I have to do (I got the coach de-fueled today) is locate the leak and make sure it gets dealt with when I replace every piece of rubber in sight and add the separate fill vents and, maybe, have time to try to deal with the problematic vent liquid trap dealy thing.

I think you'd need holes in the floor to use that solid-line method of
fuel delivery.
Still not betting I won't have the tanks down one more time. :^)

Why?
I didn't put holes in the floor when I installed my in-tank fuel pumps and steel fuel lines.
I know many others that didn't either.
