securing copper fuel lines to the chassis
ok, so after a lot of thought, i decided against plastic fuel pipes for now, as i'd have to get ones with all the right numbers on them. decided
to go copper for now.
went to the marina, and got some copper fuel pipe and fuel hose from the shop, which i never knew was there! loads of useful stuff from battery cables
to proper fibreglass supplies. fuel hose is marked ISO7840, which related to marine grade petrol/diesel hose with extra fire resistance. seems good,
and cheap too. got everything i need for £12. bargain
anyway, need to find a good way to secure the lines to the chassis. down the tunnel is fine, i can put P clips through the tunnel. I'm also
running the copper pipe inside some central heating pipe for a bit of added impact protection, i will also be putting it inside some heat sleeve when
i've got money, as the exhaust also has to run through the tunnel. theres no other way to do it really.
the back half of the car though, the fuel line has to run from the tank, down a chassis tube about 1.2m down to the pump and then tunnel.
I don't want to drill holes into the tube if i can avoid it, at the moment, i've split an old cotton braided fuel hose down the side, and
slipped the copper hose in that for the full length of the pipe. can this just be tie wrapped to the chassis? the pipe is protected by the hose, and
the squishyness of the rubber stops the tie wrap from moving, as does various welds to other tubes, and brackets.
how does that sound?
edit: just looked at CBS for fuel stuff, copper pipe, £7 per meter! mine was £2.60!

Nobody?!
OK, Personally I'd want to do someting a bit more engineered, inspectors opinios vary too
How about using rubbrer lined p clips as the clamp to the chassis tube with a plastic p clip holding the pipe?

i used rubber lined metal p clips, one on on the chassie tube, one round the pipe in a few places were i didn't want extra holes was ok for SVA
test, also in another place were it got a bit tricky, pump, filter and lots of open space i made a alloy plate, drilled and riveted in 4 or 5 places
then mounted bits to that and p cliped pipes to that too to reduce the number of holes

interesting! never thought of that way! might cause a few issues in some places, just gets a bit tight for space in places, but a very good idea!
here's some pretty vague photos, its not an asy area to take photos of really.
 
Description
there is some convoluted plastic pipe in there too, this is where i was going to put electrics, but will go somewhere else now. the cotton braided
hose over the copper pipe goes the same way though
and this is where it goes down to the pump
 
Description
can't imagine my way is less secure than these eBay Item
