Josh Posted November 12, 2007 Share Posted November 12, 2007 Are you allowed to run fuel lines through the car ie, under carpet?? Im thinking no, but can it be covered with a cert or anything? Would make life so much easier if you could.. Quote Link to comment Share on other sites More sharing options...
Ke36 Posted November 12, 2007 Share Posted November 12, 2007 no/flag that anyways race cars you can but doubt you can on the street Quote Link to comment Share on other sites More sharing options...
Requiemk Posted November 12, 2007 Share Posted November 12, 2007 ring up certifier etc, someone had to say it. Quote Link to comment Share on other sites More sharing options...
crazy_rich Posted November 12, 2007 Share Posted November 12, 2007 shouldn't be too hard to run your fuel lines under the car, its already got holes in the boot floor and you'd have to make some holes in the firewall anyway, mine's already got half ass mounting points under the car for the standard fuel lines too. I've just started piecing my fuel system together too, should really update my project thread ay. why would it be easier to run them through the car? I'm 90% certain its illegal to run them internally. Quote Link to comment Share on other sites More sharing options...
Gaz Posted November 12, 2007 Share Posted November 12, 2007 I had a street car with braided fuel line clearly run through the car and it got Wof's. It wasnt certed for it either but it was certed for other stuff. Anyhow it aint hard to run it under. Just go buy p clips from Repco to attatch them under the bodya nd run them up the side of a chasis rail or similar. I just got some to run my battery cable under there and it was $14 a bag of 10. That was for huge ones tho so itd be cheaper. Gaz Quote Link to comment Share on other sites More sharing options...
Josh Posted November 12, 2007 Author Share Posted November 12, 2007 Yea was just checking anyhow. I'm just worried about the rubber lines being close to the exhaust/having to cross over it at one point was all. All good will just run it underneath, not to much of a big deal, have to heat wrap the lines and exhaust or something. Quote Link to comment Share on other sites More sharing options...
peteretep Posted November 12, 2007 Share Posted November 12, 2007 why not buy steel lines? Quote Link to comment Share on other sites More sharing options...
Josh Posted November 12, 2007 Author Share Posted November 12, 2007 Because that just looks like a right cunt to bend all that up/need a bending device,, and I already have the efi rubber stuff. Quote Link to comment Share on other sites More sharing options...
Guest sexychevette Posted November 12, 2007 Share Posted November 12, 2007 yeh im keen to run massive fuel line through the chevette. Scared of zuast heat since i seen that rxbongo burn to the ground. chevette will never see a wof tester again tho so fuck legalitys. Does anybody know of a website or something that tells you shit about the safety standards you have to meet for a track car? ive seen a few racing cars with massive fuel lines running along the floor, so i guess its alright Quote Link to comment Share on other sites More sharing options...
crazy_rich Posted November 12, 2007 Share Posted November 12, 2007 seriously, bending steel fuel line = thumb and forefinger, makes for a nice clean job in my opinion. Quote Link to comment Share on other sites More sharing options...
zep Posted November 12, 2007 Share Posted November 12, 2007 Because that just looks like a right cunt to bend all that up/need a bending device,, and I already have the efi rubber stuff. I'm pretty sure you're not alowed to run rubber lines the length of the car. There is a new kind of line/pipe on the market (I have it for my brake lines), it's goldish in colour rather than that brass colour and you can bend it by hand no sweat, realy maluable. 'Tis made to make it easy to do with no pipe benders and shit. Quote Link to comment Share on other sites More sharing options...
RT Posted November 12, 2007 Share Posted November 12, 2007 sure are, I've run full length rubber efi hose for years. Nothing wrong with it. Efi rated rubber hose is extremely tough stuff. (Fuck I even ran non-efi rubber hose for about a year until I noticed the cracks and realised that it wasn't efi rated lol) Josh, for peice of mind cut a wee bit off and try and set it on fire with a ciggo lighter.. it won't melt or catch alight. Imagine having rubber hose inside the car when some bitch puts her heal on it and the car leans out.. boom. I had to cross the exhaust under the line. No biggy, just clip it as far away as you can, and wrap the bit of exhaust, and I even wrapped that bit of fuel line with heat sheild material for extra peice of mind.

filthy one Posted November 12, 2007 Share Posted November 12, 2007 Hey Josh Yea mate go to a brake shop get some truck brake tube (10/12mm} its what i used & you can bend it sweet I'd still heat wrap the the exhaust wheres it close . Colder the fuel faster she''ll go I also went to Mitre 10 they have by there bolts n shit little plastis pipe clips {suit all sizes} all you need is a hole in the floor & they push in easy as & they hold the fuel pipe tight as a nuns whatsit & look tidy Quote Link to comment Share on other sites More sharing options...

Or other option is to run it up to the engine bay then cross the firewall. Or poss run across boot floor before you take it under the car?

corrupt Posted November 12, 2007 Share Posted November 12, 2007 maybe have a section of the fuel line which isnt rubber which only runs for the bit that crosses over above the exhuast? Quote Link to comment Share on other sites More sharing options...
Josh Posted November 12, 2007 Author Share Posted November 12, 2007 Mint, lots of good info there. Already got the efi rubber stuff filthy so will use that. Didn;t know that the steel stuff was that easy to bend eh otherwise may have gone with it. As for running across the boot floor then down the other side, well the exhuast starts on the right of the car and crosses over underneath and comes out the right. Whichever way I look at it, it's got to cross the exhaust or otherwise go like 1.5m extra and still get really close. I will cut a piece of RT and burn it, make me feel better and what not. Where do you get that heat shield stuff? I'll wrap the exhaust in heat wrap but cant you get foil type stuff that's like a heat shield, would be good to wrap the hose in.

th130 Posted November 12, 2007 Share Posted November 12, 2007 You can run fuellines through the car. My fiat has internal fuel lines, came like that from factory. Never any issues at wof time. Quote Link to comment Share on other sites More sharing options...

'Tis made to make it easy to do with no pipe benders and shit. Im pretty sure that goldish colour stuff is a copper-nickel alloy. If it is, it is the same stuff you can use for brake lines. In the past brake lines used pure copper but it tends to workharden with movement and then break/split. Copper/Nickel is better, easy to bend.. depends on the diameter tho I suppose. Theres a good question, what size do you need? Weve got to run a new one on Chris's escort, 2L Pinto, what size should we use?? Quote Link to comment Share on other sites More sharing options...

You can get away with standard but if you need to run a new return line (depends on what carb he has) then ya might as well upsize. Run 3/8 if you need to run new line.. or whatever the metric equivilant is, if you run metric then find a mk2 tank fitting as it'll have metric out's.

fishtailfred Posted November 12, 2007 Share Posted November 12, 2007 I did my 3/8 lines without a tool by hand, it was a bit of a cunt because of the size and the interaction between the cab and chassis/flat deck frame, but the smaller stuff is easy to bend even in steel. if you use steel, the flow of fuel through it will keep it cool whilst its running, and at shut down, it will only vapourise it at worst and push it out through the regulator. no O2 can get into the line, so it cant catch fire. rubber should only be used at each end to join hard parts that move relative to each other.
