| Post subject: | Braided hoses for registerable cars |
Can anyone who has rebuilt a car requiring a blue-slip (NSW - RMS) having used braided hoses please enlighten me on a braided fuel hose product (or products) which can be used that comply with RMS requirements and also comply with CAMS general regulations please  We see braided hoses on a variety of registered street-rods, custom cars etc. Maybe there are links to other chats on this:?: I just want to understand the logic also on why braided hoses are poo-bah'ed. Help please!

Don't specifically know about NSW rules, but you can get braided hose which is DOT approved, or ADR approved or some such. Usually some identifying mark on the hose to prove so. That should be all you need for roadworthy legality. Could be mistaken though. |

The only hoses that have any regulations are the brake hoses. They must comply to ADR rules. |

If you are referring to CAMS Group N ...Historic cars... Brake hoses are "Free"... use what you like. CAMS General REGS Schedule A... Brake line[the long ones from m/c to each corner] must be steel "Bundy" tubing.[not braided] Chassis to Brakes... please yourself. NSW Rego rules... wouldn't know, but in SA we don't have Roadworty Inspections . |

Nah....other materials like copper DON'T rust....hmmmmm |

I've just recently spent a bit of time researching what is legal for road use on a Mini here in SA for my current project. Only ADR approved brake hoses may be used here in SA, if you stick to ADR approved stuff for everything you'll be find. Can't see that it would be too different interstate on this. You can pickup ADR approved braided hoses from Minisport.com.au here in SA. You'd be amazed at what's legal and illegal here in SA, can't speak to much of interstate rules as i haven't looked into any other state. As a general rule try to make sure things are ADR approved, brake hoses, seats etc. Seat subframes can be made yourself without needing to be engineered here in SA. As long as they are made to ADR rules and standards. Hope some of this is of use. |

Bundy is an interesting pipe, it isn't just a tube of steel, it is a flat sheet rolled into a pipe so it is actually layered and then welded. Copper may not rust but it does have its own problems with work hardening and cracking. |

How would one know if these were NSW legal? http://minispares.com/product/Classic/B ... o%20search |

You can buy ADR compliant flex hoses (Goodridge make compliant hoses) - but you need to check the NSW rego rules to see whether they allow them. ADR (ie Commonwealth regulations) compliance does not guarantee acceptability under NSW (ie State) regulations. Cheers, Ian |

Quite right, Goodridge hoses are ALL made to exceed the standards to which they are made for. Even their custom made ones are ADR complient. |

If you go to your local pirtek/enzed etc. they can make ADR braided lines to suit. As for fuel lines you are free to use braided AN lines on the street, not sure about CAMS/Historic racing regs. |

How much pressure are you running that you need braided lines or is this cosmetic?

Thanks guys for the input. There was a lot said about brake hoses and thanks for the link to the UK Minispares. My question was about fuel lines as Mini Mad observed. No Kennomini - not cosmetic. My understanding is that CAMS require braided fuel lines (irrespective of Na Nb Nc historics etc), and I have been advised from a number of sources over a period of years that braided hoses are not RMS acceptable (NSW). Then someone, whom i cannot remember, said there is a type of braided fuel line hose that is acceptable. And then i had no idea as to whether that person's advice was correct. The logical next step is to throw it to our wider knowledge base. Don't get me wrong, I'm not ungrateful for your combined efforts, however, I still don't see that there is a conclusive answer to the type of braided fuel hoses. CAMS Manual of motorsport - 5th Category historics - 3.6 explains permitted use of braided hoses on brake clutch oil and fuel, and for rally cars it states: Schedule R – Rally Cars CAMS Manual • • when flexible, these lines must have threaded, crimped or self-sealing connectors and an outer braid resistant to abrasion and flame (will not sustain combustion); • the minimum burst pressure measured at the noted minimum operating temperature shall be: Fuel lines (except the connections to the injectors and the cooling radiator on the circuit returning to the tank, including any cooling radiator or lines): 70 bar (1000 psi) at 135°C (250°F) Lubricating oil lines : 70 bar (1000 psi) at 232°C (450°F) Lines containing hydraulic fluid under pressure: 280 bar (4000 psi) 232°C (450°F) Notwithstanding the requirements detailed above, if the operating pressure of any the hydraulic system is greater than 140 bar (2000 psi), the burst pressure shall must be at least double the operating pressure. Note: Steel ‘bundy’ tube which is designed for use in automotive applications will usually comply with the minimum burst pressure as will many flexible braided lines designed for fuel injection systems. Reputable hose and line suppliers or manufacturers will be able to provide specifications and documentation (eg, a catalogue) that can assist the scrutiny process. The above leads me to acceptance of braided lines for competition cars. On the RMS website you can get to the ADRs, and I have found that file 7/00 and file 17/00 seem to be the relevant documents but they are not internet accessible. I might send and email enquiry to RMS to see where it takes us. After all - its my question guys... http://www.rta.nsw.gov.au/registration/ ... i_dl1.html and VSI 07 is as far as I could go (for those interested). Oh and... Happy New Year to one and all!!!
