Fuel Lines: Clean or Replace?

[cobrar96]

I just recently purchased a 77 911S that had been sitting up for 12 years. I'm going through the fuel system and am trying to figure out what to do with the fuel lines. (On a side note, I have already replaced the fuel tank, filter and pump and plan on replacing all of the associated hoses). Yesterday I sprayed the lines with compressed air and they didn't seem to be stopped, but they had a lot of powdered rust inside of them.

I'm trying to decided if I should try cleaning them or just replace and be done with it. Does anyone know of a good way to clean them or can suggest a good cost effective replacement? Any thoughts or suggestions will be greatly appreciated!

Regards,
Randy

If it were my car, I'd replace the lines. Several options, do a search and you'll find lots of discussion about this.

I'd say collect a half gallon or so just before the filter and see how it looks.

Isopropyl alcohol will clean them.
BoxsterGT (Len Cummins) will likely have exactly what you need to replace them.
