Braided SS fuel hose / progress update

[scottbooth]

Hey everyone...

I have finally turned the corner and am into the reassembly phase on my 78 SC track whore. (If there were a Guiness record for the most complicated Carrera oil cooler install, I would have some beer. Mmmm Guiness.)

I previously posted about my torsion tube welding hack job, but prefer to ignore the hell that was the stripping and re-painting of the tub. In the mean time I seem to have developed a fragment of skill for sheet welding, as the body rust patches went well. I have tons of photos that I have not shared. I suck.

Back story on the fuel plumbing. Skip ahead 2 more paragraphs if you want.

The hoses at front and back looked like crap, and the couplings were solid rust rusted to more rust. I might have should have just left the rusty couplings alone, and replaced the flex lines from the barbs outward. But there was a lot of rust, and I like to add unnecessary complications.

So with the much needed help of some drinking buddies, I pulled out a bunch of really good looking 30 year old plastic fuel line (this ***** holds up nicely) and pulled in some good ole 'merican 5/16 stainless tube from Summit Racing. (I had tried to get the original lines from Pelican but they couldn't get the lines from Porsche.)

So now I am doing 6AN hose at the front and back. Hindsight says that picking the rubber hose over the braided would have been the better call. But the braided stainless hose was shiny, and very race looking, so I bought it.

Finally, my point: I have seen this done on several members' cars. I am using the factory routing thru the welded body clips at front and back. I was thinking of putting heat shrink tube over the hose so it would not chafe on the body, since these hoses are crazy abrasive. Or is this not necessary?

I don't care much if I wear thru the flat black chassis paint that I sprayed on the tub, but I really don't want to wear thru the Rust Bullet coat underneath and create new places for the tub to rust. That was not the point.

I apologize for being so long winded, and thanks for any advice.

Good foresight. Use Adel clamps (cushioned hose support clamps) attached to the chassis w/sheet metal screws. Heavy duty heat shrink is heavier and may be helpful in certain areas. Use rubber grommets if the hose passes through sheet metal openings.

However, factory replacement works well here and may not have the same weight penalty.
