I wonder if the aging of the lines is something environmental. My original car has the original plastic that are still super flexible. The Ohio car seems to be good but I haven't tried any torture testing of the lines yet. I bought a set of Chris's lines primarily for the high pressurelines in the engine compartment. When I take the plastic ones out I'll try flexing the crap out of them to see if they will break.

Trivia - these lines are actually nylon. My neighbour is a polymer chemist and put a sample into a spectrometer - came out as nylon.

I'm nearing the end of a conversion project, and after the 3.2 was installed I decided to go back and replace the fuel lines. CFR shipped them to me during the Christmas rush and they seemed to get here in no time at all even though it's a coast to coast deal. The lines are works of art. They went in fast (less than 1/2 hour total), and I feel confident they're a safe solution. The old lines were supple, but discolored. So I probably could've gotten 50K-100K more out of them with increasing worries and concerns every time I sniffed gasoline in the air when getting into "OOMPAH" for a drive.

You'd have to be a pretty cheap SOB not to want the peace of mind.

what year model were the tested lines? I have heard that front fuel pump vs rear fuel pump was different material doe to pressurization. perhaps your friend can help us prove this. I could pull some early vs late year lines as samples

On the 75-76 (front pump) I most likely would change the lines, but I have a '74 so they are low pressure.

Not cheap, just not into make-work projects, all my hose and FI clamps are new. I have had 1 fuel leak, stopped and had the car towed at first wiff. Brand new OE fuel filter had a crack in it, new lines wouldn't have helped.

OK, slightly off topic - Transmission Mounts!

I just updated my old transmission mounts to the 911 Sport mounts. Not a big deal...

But take a look at the mounts that came off my 914:

Doesn't look too bad, uh?

Uh, oh. Totally torn all the way around...

This was a disaster waiting to happen!

Please take a look at your transmission mounts NOW!

Part number for the above?

Thanks!

pete

P.S. I once saw a daily driven 914 (burgundy 1975/76) sitting at the toll plaza parking lot with the back half of its transmission hanging out... sitting on the ground.

Now I never see it anymore. (IMG:style_emoticons/default/idea.gif)

(IMG:style_emoticons/default/agree.gif) That is the exact part number I used from Pelican Parts for the Transmission mounts.

This part number was highly recommended in this forum and fit without any difficulty. WEVO (member vendor forum) makes a mount that looks fricken awesome, but it's a bit too pricey for me right now.

Good luck

I replaced my fuel line a few years back, before I knew about availibility of S.S. , and a local firm specializing in hose products recommended urethane tubing. So far it's working out fine and was an easy install, but if anyone is aware of a specific problems with it, I'd like to know.
