Fuel line
Hello,
i am thinking at the fuel lines on my Tiger cat E1 kit.
I will be running two 8 mm ( inside) diameter rubber fuel hoses ( EFI engine).
I am looking for clips to fix the hoses throught the tunnel.
Another solution would be to put the rubber hoses into rigid plastic pipes ( like for electricity).
What do you think of this solution ?
IVA friendly ?
thanks for advices,
Gerardo

Personally I would not use long lengths of rubber hose to run fuel lines - see a production vehicle.
Copper microbore tubing is fairly common if secured properly and protected against fatigue. Plastic coated steel can be used if you have suitable
tooling to shape it/work it. Put a bead on the end of each tube to secure rubber hose.
Keep the flexible hoses to a minimum at either end and inspect regularly for perishing.
I don't like braided hose for fuel - no advantage in a standard kit and not easy to inspect.
In My Humble Opinion.

I used copper heating pipe and plenty of "P" clips to support it. I also painted it with Waxoyl, and encased it in a bit of split
convoluted tubing to stop stones etc from denting it.
Keep the fuel pipe as far away from any wiring as is possible. (It was a SVA failure point, and is probably one for the IVA too).
I just soldered brass pipe olives onto the pipe to get the flares. You dont want a hose coming off especially if its carrying 60 PSI of petrol! Its a
Major Fire Hazard / instant Flamethrower job in an accident.
1. The point of a journey is not to arrive.
2. Never take life seriously. Nobody gets out alive anyway.

I know there is a Cost implication, but would the aeroquip type braided hose pipes be OK? I think this is what is used in race cars.

Im about to install my fuel pipe work. As mentioned im using 8mm copper piping with gas bottle fittings on either end similar to this...

Cant find the exact site I got them from.

i was going to use braided hose, but when it actually came to it, I got 8mm and 10mm copper fuel pipe from a boat chandlry shop, £1.30 a metre or
something. through the tunnel I put it in a suitable sized plastic water plumbing pipe to protect from any wiring faults, heat from exhaust (which
also has to go through the tunnel) stones etc. if it splits, the plastic pipe will stop fuel spraying anywhere.
it was cheap enough, and actually very easy to work with tbh, not so difficult to consider changing my mind to rubber mid way. it was all done and in
within about 30 minutes

Thanks for advice.
I think i will go the copper pipe route.

Race vehicles are maintained before and after each event. Fuel lines are regularly replaced and components are dated and "lifed". Also
they frequently run where they can easily be seen.
Modern fuels have some very nasty additives that can damage even the best grades of hose - keep them to a minimum.

Fuel Pipe Clips
Does anyone know of any regs for the maximum spacing of fuel pipe clips (P clips). e.g. every 25cm?
Or does anyone have any personal experience of what vehicle inspectors like/don't like to see?
I shall be using 8mm kunifer piping, doubled for the fuel in and return line, run along the side of the chassis rails.
Thanks in advance.
