hmm hope I dont have to go and replace the lot for he sake of 3 feet as the rest is fine.

We think someone we know may have an appropriate flaring kit, hes bringing it down later. Fingers crossed.

I think they get sourced directly from Pirtec in that they come around in a van and assess/deliver.
I'm quite comfortable with the flexi-hose option actually, seems a sensible rustproof way to solve the prob... Not sure if/how they degrade over time though.

Well we have managed to find an appropriate flaring kit. Should be up and running tomorrow if the weather holds off.

Well it ended up being a mixture of copper and pipes from Pirtek but the car is running again.

Next month Ill have to do the brake lines though. Ill post some pics later.

I also now need to replace some of the 4 gang clips that carry pipes under the car - anyideas where I can get them?

OK - heres the new ones (removed ones first).

Those pipes look bad, i think i'll have a look at mine

i'm a bit confused about the concesus of not using copper pipes because of sacrificial metal as surley brake pipes would not be copper either, but they are common place ?.

TBH we just used what ever we could get our hands on that would do the job without having to take the back end apart. Next month we'll be doing the brakes in a very similar way.

YEE-HAAA

A question for the people that have used Pirtek pipes, are you saying you have used the flexible braided pipes as a replacement to the hard steel ?.
I'm looking to change mine and the flexible braided ones look to be much easier to fit than having to bend any hard pipes to fit, regardless as to wether i go for original steel or copper.

For Ease the flexible ones from Pirtek are easier and I am personally happy with how safe they will be. From a technical aspect Im not the one to advise whats best though.

I think the difference is that there is very little "flow" in brake pipes. The theroy is that as the fuel flows down the pipe it effectively rubs the inside of the tube and this creates a small static electric charge. As this charge earths to the car body the softer metal suffers from Bi-metallic corrision. I work in an industry with alot of copper to steel connections and I always put a tinned liner in the fitting to prevent this effect. However I design stuff to last 40 years and I think if the new fuel pipe lasts that long you'll be doing very well!

Hi Dave,

I'm interested in the that "tinned liner" in the fitting, do you mean a short top-hat shaped insert , how does the fitting seal ? does it have a flared end that fits into a cup or ?

Just got me thinking !

cheers

There are braided flexible pipes which are advertised as having a carbon liner to prevent static buildup, so maybe these are the way to go. Having said that if they are stainless steel will there be a problem ?

I'm also interested to know of peoples views as to whether flexible pipes running along the bottom of the car will be o.k legally, or if they should be solid to prevent them hooking on anything ?

I work with electrical fittings so not sure if there is any liners available for pipe fittings. I would imagine they aren't needed though. Where the pipe connects to the pump or connectors, it is a steel to steel interface so there is no bimetallic corrsion effect. There could be a small effect with the copper pipe at the steel fitting but a bit of grease would solve that as it would stop the oxygen getting at it. The only place I'd have thought it could happen is where the pipe is clipped to the body and again the effect would be very small but could be prevented with plastic or rubber lined P clips. You have to make sure the pipe is earthed somewhere though (to the pump body?) or the static charge will build up. I don't know how far it would go but I'm pretty sure a static charge is not a good thing to have around fuel!

I would have thought flexible lines are OK for road use. I'd use alot more clips under the car to make sure it didn't snag on anything though and it would be quite expensive.

I picked my car back up yesterday after having the fuel lines replaced around the rear end. As mentioned previously - I went the Pirtec route. The offending sections were removed from the car by my mechanic, these were given to Pirtec who made some replacements with their flexible hose and equivalent fittings that could be put straight back on the car. The hose itself is serious stuff, won't kink even if tied in a knot and pulled and is generally hard wearing. The lines are fixed to the chassis, yes, I suppose they could be ripped off by some obstruction but I'm sure the same obstruction would destroy the equivalent 'hard' pipes.

I'll try to take some photos today. Cost of lines was a little over £200 and an hour and a half's fitting.

Did they change the piping from the tank to the fuel pump/filter ?..or from the filter onwards.

I have'nt stripped the cover off to look a the pump area piping but my filter and forward piping is similar to Gazza's...f**ked.

cheers
