Fuel lines

[R. Boger]

I did a search on replacement fuel lines on the board and nothing was said about using rubber fuel lines. Is there a reason that you should not use these? Saw where some used flexible braided and some used steel line and most said they were a pain to work with and make the connections. Looking for a safe and cost wise method. Also I'll be using carbs.Thanks!!!!

If you're talking about the lines under the fuel tank and in the engine bay, that is what is used in the stock injected car. Should be perfectly fine for a low-pressure carb'ed application.

If you're talking about the lines in the center tunnel, I really wouldn't. Those are "out of sight-out of mind" items which you won't remember to replace every other year like the lines that are easy to see and remember. So chances are decent they'll leak on you. Plus there are a lot of things inside the center tunnel, some of which can abrade against rubber hoses. (Or be abraded by braided-SS hoses!)

I personally would stick to using hard lines in the tunnel, be they aluminum or SS tubing, like in Wayne's tech article. I think the SS brake line tubing would be the preferred solution; you can put a bead on the end to help keep the hoses secure when you clamp them on, just like the stock fuel rails have.

Randy, i'm awaiting my final shipment of Cohline parts (hopefully this week). I'm making complete replacement fuel line kits for the 914. It will consist of hardlines through the tunnel with soldered threaded fittings, along with tin-coated (like stainless) braided lines with crimped fittings. Cohline is OEM for many Porsche fuel, brake, and oil related parts. Plus, you can always replace the lines by cutting the crimp and re-crimping with new lines and fittings. Again, everything is metric fuel line male and female fittings, so its easy to remove. There will be several options depending on what you want, so I can supply you with as little or as much as you want. Plus if you have a custom setup, ie: different fuel pump placement, i can make your kit to suit.

I will post pics of my install on my 914. I am hoping that a full replacement won't cost more than $200.
