944 Fuel lines

[PSH]

Hi Eddie

I think but could be wrong, that the long lines under the car are now in two sections rather than the very long single pipe. I'm not sure whether this now negates the need to drop the torsion bar etc or not. Perhaps someone else has done this recently and can say, yes..no As for alternatives, I know that some have 'cut and spliced the fuel lines, personally I'm not a fan of cutting corners here. That doesn't mean I'm against making up one's own lines when using the proper tooling/fittings.

Cheers

Pete

i am going to use Cuprol Nickle Fuel line. you can buy it off ebay ect, but will need to buy fittings to go with it and the appropriate tool for moulding the ends just like a copper brake line , then the parts that join to a compression fitting will need to be purchased ect.

i will try to forward a youtube link to a guy that did it on his 944 turbo in the states if i can

Hi, anybody got a reasonable viable long term solution for replacement of the fuel lines on a 944 . I can only guess that many owners have had this problem . I know the Porsche solution... £1000+ for parts then drop the back axle.

Hi. I am thinking of doing mine this year. My pal, who is a very good Porsche indy, reckons do them in nylon stainless steel braided stuff. He was talking £500 all in for parts and labour and should outlast me and the car!!

My flexible lines in the engine bay are stainless in race-spec protective sleeving, they are also longer than standard so that they can be fed along the cam tower and avoid hanging over the manifold.

Haven't some people on here used Pirtek for this and/or brake pipes?

I seem to recall RPM Technik were doing this at one time.

If & when I need to replace the existing fuel lines on either of our 924S's,I will use copper fuel pipe for diesel trucks with ends prepared /fittings from my friendly Bootle Brake & Clutch factors who I've previously mentioned in regard to replacement brake lines

When I did my fuel lines ~ 10yrs ago - I took both (inc. the crumbly bits at the back) to hydraulic specialist in High Wycombe (Spectrum Hose) - as it was only the rear section that was corroded he made up SS braided flexi lines for the back (over the axle) and front (up through the wheel arch/ over the cam tower) - this was with compression fittings, olives etc.

It's funny because when you speak to Hydraulic hose specialists who are used to dealing with ~ 150 Bar - when you explain that you need fuel pipe for ~ 3bar/ 45 psi they're like " is that ALL....."

It shouldn't be too difficult for a Pirtek/Spectrum hose type expert to produce 2 parallel SS Braided hoses from the rear to the front - despite e-bay/ Demon Tweeks prices Goodridge/Aeroquip tube isn't that expensive - mostly the fittings and construction thats the cost.

In consultation with my Indy he's fitted Nylon Braided PTFE/ Teflon Hoses. at least these are one piece front/rear right to the Injector rail. cost incl labour and VAT just under £700. that includes new clips fittings etc

I think Porsche has the correct solution albeit expensive and pretty impractical to the home mechanic. There is a well know southern based Guru who has some interesting things to say about various solutions and Ethanol.... and the effect of Ethanol on Injectors
