Rubber pipe in tunnel?
Colnago_Man - 1/2/08 at 12:11 PM

While test firing my engine I used some regulation rubber fuel hose. I've now decided to fit this into the transmission tunnel, knowing how difficult
it can be to p-clip rubber hose without it drooping I though about fitting some lengths of L shaped ally the lenght of the tunnel and fitting the
fuel pipe onto the horizontal surface (may be with p-clips and a self tapper).
I may also do this for the electric wiring on the opposite side of the tunnel.
Also this may provide some extra protection for the fuel pipe in event of a diff/prop shaft failure.
I guess the question is would it be acceptable for SVA?

why not ust run a copper pipe through the tunnel like the brake pipes?

quite right

Your layout looks good - but I'd also recommend metal tube through the tunnel, as you'll only have to replace the rubber when it eventually perishes (mine took only 3 years to go). In my case it was a total PITA to change, as trying to get around the propshaft and gearbox was extremely difficult.

Yep hard line I'm afraid, whilst SVA man might be o.k. with you set up the rubber will perish and need changing after a few years, and that's going to be more difficult latter on.

You could always use a ridged plastic pipe (edit: pipe by definition is ridged, hose is a flexible pipe...) designed for fuel this would be easer to fit than the copper pipe..

another vote for hard line. go on, it makes snese in the long rong - pity mine was not built like that, at some point I am goona have to replace it and it ain't gonna be easy.

Personally I doubt if the alloy angle would offer much resistance to a broken propshaft flailing around - but then nothing will. Plus you are adding extra weight too so I would do as suggested and fit a rigid pipe (kunifer or copper) which will take up less space and last the life of the car.

Similar to how I did mine...



Single brake line down and feed and return fuel (just in case I upgrade to a zetec)

Electrics down the other side in convoluted tubing p clipped to the side.

Yeah, use copper (a roll of 8mm microbore central heating pipe from B&Q for a tenner works perfectly). It makes sense to put a return in now even if you're going to run carbs as you may want to upgrade to injection in the future. (Wish I had!)

Thanks guys, the fact that the rubber might perish never crossed my mind. Copper it is, and yes I'am running carbs but its a great idea about fitting a return line as I may indeed upgrade the engine in the future...
