REFLECTOR: fuel line fittings

[Alex Balic]

Hi Noel-
The reason for not using tape is the possibility that some may dislodge and
jam up in an injector, fuel flow sensor or the like- the preferred sealant
for pipe threads (in my opinion) is the Teflon paste- it is inert, just
about a slick as the Teflon tape- which is what you need when tightening
pipe thread,, and as long as you are conservative with it's use, should not
pose any threat to anything downstream- you should wipe the material into
the male threads with your finger so there isn't any extra sitting there
that could eventually become dislodged.

Any thoughts / consisus on fuel line fittings?
As in steel vs alumin?
My guess is that the tubing is alumin, why not the 
fittings?

If I'm using an822-6d elbows, then do I need an818-6d nut 
and an819-6d bushing?

When I do house water pumbing, I use teflon tape in the 
fittings.
I've heard not to use teflon tape in fuel fittings...
Is there a prefered sealant?

Noel
