Larry,
I
haven't had any "sweating" issues with my steel braided lines or
fittings. As long as you properly assemble the fittings/lines they
shouldn't leak. Ensure the ends of the fittings and internal threads are
well lubricated before putting the pieces together, and it helps to have a set
of aluminum vise jaws and aluminum a/n wrenches when you assemble the
fittings.
Before I installed the rear sump, I had a worm gear clamp to hold the
braided line to the sending unit's barb. I don't know if that was the
right way to do it or not, but it worked with no leaks.
As
Dale mentioned, the a/n fitting seals on the 37* flare, not the threads.
However, you can use Teflon tape or thread sealer on the pipe threads of the
a/n to pipe thread adapters.
Also, the shut-off valve is a great idea to include in your fuel
system, especially when you need to disassemble a fuel line or change the
filter. It's also makes a good theft deterrent.

Herb,
Thanks for your input. I'm still learning my
way around cars after a 25 year break while serving my country and raising a
family. This is my first time working win AN type fittings...
1. As Clint mentioned, have you
experienced any "sweating" or leaking issues with
AN fittings?
2. What type of fitting would I need to get to
attach the braided stainless hose to the tank sending unit's barb
fitting?
3. Would the use of teflon tape on the threads
be appropriate on fuel lines?
Thanks for your help.

Hi Larry,
You've got the right idea going with the -8 line. Right now I
have -6 supply line from the tank (modified w/ rear sump), to the
filter, to the pump, and then -8 from the pump to the carb. However,
I'm in the process of getting the pieces to convert all the -6 to
-8. As for the filter, I originally had an inline type filter on the
frame rail by the engine mounted fuel pump but found out that any large
debris caught by an inline filter can significantly reduce fuel flow
at the worst possible time - at the drag strip! After that happened
I mounted a Fram canister style fuel filter back by the gas
tank. Also, I covered the line from the pump to the carb with Thermo
tech sleeving.

Doug,
I was thinking about running a braided hose
all the way as well. I have the same concerns you do, so I'm planning to
go with Summit p/n SUM-PUMPKIT3 which is a - 8 AN diameter fuel line kit
designed to work with 3/8 in. NPT components. That's my plan
anyways, unless somebody here can speak up and tell me I'm headed in the
wrong direction.

I am doing the same thing on 66
chevelle 400 SB 750 demon carb. I am going to run braided -6AN
hose all the way and put a filter in line. I am using -6an
connectors no clamps!! my only concern is that -6an hose is .032
smaller in dia. hope this is not too small for my
750 carb??????

I'm getting ready to run new fuel line
from tank to my mechanical fuel pump (Holley 110gph) to carb. Any
suggestions concerning type of fuel lines to use, and what you are
using to filter your fuel and placement of filter(s) would be
appreciated.
Also, is anybody out there insulating the
fuel line coming up to the carb?
Thanks,
Larry
