1970 -6 Gas Tank Supply Pipe Hose Bead Question, Morphed into: “Does the OE fuel return system cool fuel going to engine?” uh … No Options

[Rufus]

Hi Folks - I have the entire fuel system out of 9140431482 back to the Webers for update, cleaning, etc. (Webers already reinstalled after thorough cleaning.) The gas tank fuel outlet pipe has no hose bead.

Is this normal? Seems odd there wouldn’t be one.

Thanks,
Bob

Bottom of the gas tank from my 6.

Never been touched..

Perfect! That’s what I have (except no pipe for a return).

Now I’m sure I’m headed in the right direction.

Re the strainer (sock) on the inside of the supply line. That was one of the many flaws I’m correcting. Mine was broken in 2 and disintegrating, tank contained countless (paint?) flakes from “restoration”, AN 6 SS braid hose deteriorated and leaking fuel vapors into the cabin near the shifter, and an IDA’s inlet filter was torn allowing debris, paper towel and fabric fuel line reinforcement cuttings into the floats.

Hose “bead” vs “barb”? It’s a relatively minor difference in geometry. A bead is a smooth bulge rolled into the tube vs a barb which is usually multiple sharp “teeth” cast into the nipple for enhanced hose retention. A clamp tightened behind the bead retains the hose like the sharp edges on a barb do.

Thanks for all your input. (IMG:style_emoticons/default/smile.gif)
