After recently relocating and tons of housy type work to be done, I have decided to take the Chevy K1500 off the road for a year and do a bunch of part replacements etc when I get the spare time. The one job requiring attention is both fuel(petrol) and brake hose replacement. Now I remember a few years back one could use a reinforced pvc tubing instead of copper for LPG installations but are there any modern replacements for petrol and brake lines? (approved of course!) The truck still uses a carb set up. Pictures of a nice A Reg Capri I saw yesterday in Dumfries as payment for knowledge    |

Kunifer for brake lines. Fuel lines I usually do them in stainless hard line with PTFE for the flexible parts.

Cheers bud, I have been using kunifer over the years but wondering if owt has been developed since then in some sort of polysomething or similar! If not, kunifer as the way to go for the brakes but are there some sort of flexible fuel lines in use nowadays? |

You can use PTFE for all of the fuel lines if you want. This is the OEM pipework underneath my 2000 TT  |

cars and trucks have mostly been using some kind of plastic/nylon rigid lines since the mid 90's at least.

And I won't sit down. And I won't shut up. And most of all I will not grow up.

Lots of things have been using plastic for years, but they often get problematic as they get older. (Especially diesel pipes it seems) Usually it’s the push fit fittings used to save time at assembly, they only like being fitted/removed so many times.
I don’t see why you would want to use anything other than kunifer for any of it tbh. It’s not expensive and it’s tough. Compression fittings can be nipped up if they’re not tight enough. It just works.

Just shows how out of touch I have become! I will definitely fit the ptfe tubing for the fuel then and stick with the kunifer for brakes. Its only because I would want to replace all the brake lines and with all the bends etc, a plastic type line would have been more manageable whilst lying on yer back! Just a daft idea on my part-please ignore |

I know Bad Obsession Motorsport used flexible high pressure lines for the whole braking system on Project Binky. I've not had a reason to look for some yet, but remember thinking it could be a nice solution for replacing hard lines that run above fuel tanks and subframes etc.
A quick search now and all I've found is the stainless outer braid housing for flexi replacement which I don't think is what they used...
