Outer Limits 4x4 Board

Have just removed the standard tank from my lux as i am looking at using an aftermarket cell mounted in the tub. I do not want to use the standard hard line as i will be using 3/8 in fuel line.

Question here is: can anyone see any problems running the line through the cab on the floor (shielded of course, to prevent damage). I wish to do this because if i run it on the passanger side (which i need to) under the car on the chassie rail it will run nicely past the exhaust system..... getting to hot, and also could be damaged easily by rocks etc...

i will be using "Parker" Red 3/8 fuel line all the way through to the pump under the hood. it is not EFI, so its working at about 7 psi. the line can handle 350 or something i think? its good for EFI anyway!

Opinions, concerns all welcome!

Cheers, Joe.

I'm not there to see for myself, but a petrol line through the cab would be my absolute last resort.

My 2c,

Scott

i dont see a problem with it. my complete setup is inside the cabin. plenty of cars came out with the fuel tanks under the front/rear seats. if its protected there should be no problems

im with scott, Does it really matter if the line is a metre or two longer so you can route it to the passenger side chassis rail? or better yet pickup the factory hard lines.

If I remember correctly, old model subarus run the fuel and brake lines through the cab - but they are STEEL LINES. Even then I wouldn#t do it personally.

I think that would be an ADR matter and I'm thinking it would not be allowed or advisable.

Why do you not want to use the original fuel lines champ... If the vehecle did not come out with fuel lines in the cab I would not put them in the cab.

Rally cars run their feul lines through the cab to protect them as well. There is no problems but they run steel lines through the cabin and the fuel cells are usually in the boot with a completely sealed firewall between the cabin and the boot.

Rally scutineers wont let you have any joins in the fuel line within the cabin though, it must be one continuous piece of steel line. You can get different diameter steel fuel lines, as I'm a cheap arse I got minew from a falcon station wagon at pickapart, nice long length for bugger all cost. Most guys run some rubber hosing over the steel line to protect it.

Make sure you get the right steel stuff as if its not rated for fuel the crap they mix in with the fuel these days will eat the fuel line.

In cab is fine if done right. Not keen on rubber hose in the cab, too easy to get a leak, even just from rubbing.

Hope that helps.

Catcha.

I wouldn't be too concerned about the fuel line rubbing through or breaking during normal use (easy to monitor/control), i'd be concnered about it breaking in an accident and having the fuel leaking inside the car, not out...

And i'm with roadnazi (well he should know ), pretty sure any fluids through the cab that arnt original are a roadworthy issue, and probably need to be at least engineered.

Fuel line through the cab is not the absolutely most dangerous idea I've ever heard, but it's probably not the safest either.

I am struggling to believe that your only option is to run it next to the exhaust; surely there are alternative pathways outside the cab.

thanks for the input so far. i am thinking i may just do it and see what happens. i will be running a small shut of valve between the seats incase there is a bonnet fire or big leak or something in the engine bay.

*ADR is no worries, its not regod!

I dont want to run it up the chassi rail coz the exhaust is right next to it! and damage is very likely! and i had it running on the other side but i have just changed my engine set up and fuel now enters the carb on the other (passanger) side.

Not keen on using a longer length of hose over the engine to go around eiher, simply because it will heat up and run right over all the ignition wiring/coil etc.

Anyway, i will get it done in the next week or tow and let you know how it goes after a bit of wheelin!

In my disregarded opinion I really don't see a huge problem with it, as long as it's completely protected and you have a fire extinguisher mounted in the cab as well (just in case) i can't see how it would cause such a big concern.

There are plenty of cars getting around that are deathtraps anyway without anything to do with the fuel setup.

Its not like the hose is fire hydrant size and will have your mates swinging off it like monkeys in the cab. If a fire were to start in the engine bay, I can't really see it getting through the firewall and blowing you's out the roof like cannon balls any quicker than you noticing it and putting it out. Whats the difference if its in the cab or under the cab.??

Thats like saying you would be too scared to drive a car with a windscreen incase it smashes in and you get glass chunks in your eyes and they could send you blind and make you smash into the back of a petrol truck and become crispy & charcoaled.
See the difference?

ps.....I cart around 100L of that flammable liquid that could blow me sky high (even though its at the back of car) if the "unthinkable" happened while i was driving to work.

Honestly??

***ADR is no worries, its not regod! ...i say doo it..trial and error is part of life

i would get a length of 25mm steel electrical conduit or 32mm what eva the hose can run through and run it through that i don't see this being a prob at all

Simple risk management. I've not read anything in this thread which indicates the risk is worth the benefits. Create a fire hazard inside the cabin, then carry a fire extinguisher? Dude, carry the fire extinguisher, AND eliminate as many fire risks as possible!

If you don't want to run it alongside the exhaust under the cab, then change sides. Run the fuel up and over the engine/trans along the firewall - where's the problem?

If you're going to install 25mm steel conduit, do it under the cab, on the exhaust side - not through the cab. If you're still in doubt, throw in an extra heat shield.

"Not registered" is a good reason to change tyres, rims, suspension without worrying about ADRs. But something with the potential to create a blazing fire inside the cab? Fark registered or not - be safe!

I think you're looking for external validation of your desire to be lazy. If it all goes to hell, you'll be regretting your laziness for the rest of your life.

Do it properly.

nuff said.
read that whole post roverlux, if your in any doubt scour over the tassie RTA website and CAMS site.

biggest issue is NO JOINS IN THE CAB! and make sure its run somewhere your not gunna stand on it.

the problem is a) fuel temps and vapour lock from running around exhaust and or other heat sources
and b) torn fuel lines from rocks branches etc.

as long as he has igntn fuel cut at the tank in place there is absolutely no problem at all
Simon

well id at least run steel lines through the cab

Run it up inside the chassis rail. Away from exhaust, protected and outside the cab. [o] not []o

So do ..........

Sprintcars, Super-rods, aswell as most of the production based cars running on speedway circuts. They also alow a fuel tap to be installed within the drivers reach so fuel can be shut off either at the end of the race so there is limited fuel available if theres a fire from the engine heat. Fuel can also be shut off in a racing accident by the driver, emergency crews, or field marshals.

Several classes running hardtop circut racing are also allowed to run the fuel lines through the cabin, again this is for safety reasons.

To the best of my knowledge "rail cars" & "Funny cars " are the only group in the draging world that do this prodominatly, but with this class its more of a neccessity than for safety reasons, largely its due to the design/layout of the cars themselves.

Most of the sports only vehicles I've listed will have a fuel tap fitted, this tap is always a manual ball type tap, the main safety issue usually relates the use of fuels such as avgas, methonol, nitro etc . In the case of a rail car the fueltap for the "real fuel" is switched on after the burnout by one of the crew members after the car has backed up & is ready to stage


As for a road registerd unit .............
CHECK YA LOCAL ROADS AUTHORITY FIRST

Kingy

well i have done it and its all but complete.
mounted a 5 gal. RCI fuel cell in tray.
ran line through cab using p clips.
have not got a stop tap yet but will soon. also got to put a guard on it.... have pic but dunno how to do it
