Fuel line replacement as routine or not?
Has anyone had a fuel line fail on their 993?
I am wondering whether to replace the fuel lines as a matter of course to prevent catastrophe, they are getting up there in age.

Not yet.
I take it the ones in the engine compartment where heat could age them quicker?
I had everything out of the engine compartment above the heat shroud when I replace my ignition cables. That enabled a thorough inspection of everything.
The fuel line was fine and looked as good as new, but there were two rubber-lined clamps at the front of the engine that attach to a bracket on the engine breather cover where the rubber had crumbled due to heat and age.
One clamp holds down the engine wiring harness; the other clamp hold down the fuel line.
You can just see where those clamps attach to - bottom left of the oil pressure sending unit. New clamps have been installed. The fuel line looked fine at almost 16 years old.

I don't know what condition those are in my car. I'll be getting to those when I do my shifter-forward underbody detail later this summer.
I'd think they'd be in better shape than those in the engine compartment where they are exposed to high heat, unless they use hoses of a different grade for that reason.

Just starting project will do thread when farther along. I have the engine, but I will do suspension, brakes, steering, body work, etc. before installing it, so it will be a while.

Fuel Line Part Number
I'm replacing the fuel line on my 95 C2. The p/n on the fuel line (metal rail where the injectors attach) is 993-110-040-02 and the part I received is marked with p/n 993-110-037-04. Does anyone know what the difference is between the two? They look the same but again, different part numbers?
Thanks for your help.

If your fittings are still good, you can get the hoses rebuilt for less $ than buying a complete new hose from Porsche. Call up a few of your local independent Porsche shops and ask them who they recommend for rebuilding fuel hoses. There's probably a local shop they rely on for these services.

I couldn't find any reference to the replacement part # on the Sonnen Parts site (which has been quite useful to me when finding replacement and superceded part #s for those in PET). Maybe Porsche spec'd the 993 110 037 XX number with the part manufacturer, then changed it for unknown reasons, an in the meantime, the parts manufacturer cranked out a bunch of these with the old # before receiving notification of the # change.
However if it fits ok I would go ahead and use it. It is mentioned in post # 138 by Axl911 on this Pelican Parts thread:

"It looks like the 993 line is different. It's not Cohline 370. It has "VRT 993 110 037 04 12x1.5x665PA 11W PTL 14059/02E16W...." written on the hose."
So at least one other 993 fuel line appears to have had the same # as your replacement part. If the rail mount points, injectors and clips fit, I'd use it.
