hi, i have a kghia, need to fit fuel lines for injection. has anyone put new lines in the tunnel with the car complete [not off pan]. if so any suggestions appreciated. thanks greg

Greg, I'm in the process of setting my oval up for injection and was going to copy what Humpty did with his car by running the two lines along the side of the tunnel, of course using steel lines rather than the ali ones in his thread. It may be an option worth considering, see here on page 6

thanks for the link 66brm, the setup looks good n neat, only thing is, i been reading its illegal to put the lines inside the car.

ADR illegal? I'll have a look see what I can find, I've seen US guys running flex lines through the tunnel but could imagine the pain to achieve it with the body on, and I don't like the idea of running pressurised flex lines over that distance without being able to see any issues.

From a Govt page published Jan 2011

2.1 FUEL LINES
This clause refers to any fuel hose, pipe or tubing used in a vehicle's fuel system, irrespective of
the fuel type used.
The material for fuel lines must be compatible for both the type of fuel and fuel system to be
used and must comply with all applicable standards.
Fuel lines must be securely fastened. Push-on type hose connections must be fitted with a
positive means of retention to reduce the possibility of fire due to leakage or fuel hoses coming
adrift and spraying fuel over electrical components or hot exhaust components. Where hose
clamps or clips are used the end of the mating pipe must have provision to aid the retention of
the hose.
Fuel lines must be well clear of extremely hot components such as the exhaust system or
turbocharger (if fitted). Fuel lines must be adequately supported and where under a vehicle,
must be protected from road debris and damage either by chassis/body members or shielding.
Fuel lines must be adequately protected from chafing or damage where they pass through
panels, bulkheads or chassis members.

hi 66brm, well that is interesting, it doesnt seem to indicate where the fuel line should be or not be put. was that all it had to say on fuel lines. i have only read its illegal on forums like this. so maybe its all poppycock. anyone else who knows the regulations please chime in. thanks greg

I have also hear it is illegal to run fuel lines inside the passenger area. I would check with the local rego offices to be sure though before I put them in.

When it come time to part the body on my notch I plan to run SS line through the stock location and have AN bungs as standard on the ends of the pan.

I first tried flexible lines on my notch, but didn't like the idea of them sitting loose on the bottom of the tunnel and of course the fact that I can't check them. A VL turbo fuel pump will fill a tunnel full of fuel before you can say "what's that smell"?!

Now I've just got 2 lengths of 8mm bundy tube, 90 degree bends on one end...fixed at 40cm intervals with rubber "P" clips and then a bolt securing the clips to the side of the tunnel.

At each end is a metal "cable gland" for each fuel line which when tightened will seal out any moisture to the tunnel.

At the front I have used the inspection cover to run the lines though (will be a pain if I need to get in there one day!) and at the back they run through the pan off to one side and away from the shifter linkage etc.

Had the lines double flared and have brass fittings adapting to 8mm barbed fitting where the flexible line runs etc etc.

All good so far!

Anyhow, that's how I did it. Body on pan.

thanks for u imput, yogie, vladn, type3lover. i decided i will run both down the passenger side where the body bolts to the pan. hopefully its one job i only have to do once.

my idea is to run ss lines through the tunnel and silver braze on some ss AN bungs on the ends of the lines.

i reckon that would be the best idea, if u body is off. i would do it that way if mine was

Here are the fuel lines on a 2005 Subaru Liberty inside the cabin of the car. So you can run them through the cabin of the car legally.

I did some more hunting on this one and found that its legal to run the lines through the cabin of the vehicle as long as there are no breaks in the line ie it has to be a single solid piece with no joins physically in the cabin. So my concept of passing it through the firewalls using rubber grommets and having tube to AN fittings is good to go
