Default Fuel Lines

I read that its good to change fuel lines on a 964 if they have never been changed. Just bought a 964 (1990 C2) a few months back and was wondering if anyone had any views on this?

Timely post... I was thinking of preventatively replacing all fuel lines... And was wondering if anybody has a definitive list of all.

If not, then it's time to use the advanced search function.

I have replaced all mine in the engine compartment as part of my rebuild. Not hard to do with engine out.

Definitely replace your fuel lines.

The original lines were not made for use w ethanol. That's part of the reason that the car is only approved for a max 2% ethanol blend.

Old lines corrode and clog your fuel filter. That's one issue. Second issue is with up to 12% ethanol in your gas today, being very corrosive and on top of that running through old lines, it's a disaster waiting to happen.

The difficult ones would be ones back to the fuel pump.

If they're not leaking, leave them alone. They are made from Cohline heat formed semi rigid NYLON tubing with a rubber covering. They will not deteriorate like rubber hose from ethanol.
