Cost issues aside, is there any reason for using copper instead of rubber hose for the fuel lines?? I have a spare 7m or so that's all and would be a shame for it go to waste.

either is just fine

I think though that for the SVA, rubber pipe should be marked as fuel pipe grade

Do i need to take any other precautions with rubber where it rubs on the chassis or just regular p clips?

It's Goodyear stuff and marked as fuel hose so should be ok for Mr SVA

P clips are fine as long as the tube can't rub against anything. To check, grab the hose, try to move it around, and if it touches anything consider whether it should be more secure. Don't be too extreme with pushing and pulling though.

This is what the tester will do!

I'm guessing being rubber it will touch as it'll flex quite a bit?

Proper fuel pipe is not that flexible, especially the higher-pressure fuel injection stuff.

Mind you, saying that, most of my piping is now copper, for this reason:



This bit of pipe had carried petrol for just 3 years...

I would use Copper where you can't get to it, as replacing it in the tunnel is a PITA..

In the end, it would have been quicker (and less painful) if I'd taken the engine and gearbox out before trying to replace the pipe down the tunnel...

if i understand correctly does that mean on my injected R1 indy i need high pressure rubber from R1 pump to tunnel copper down thru tunnel then high pressure rubber to fuel rail

I think most people use copper pipe for the majority of the run, with short rubber tails to make the final connections.
