Fabric covered rubber fuel lines gone porous underneath handling maybe 20 lbs of constant fuel pressure over 25 yrs exposed to road salts, etc??

The rubber underneath the fabric cracks after a couple of decades, then fuel bleeds through tiny cracks into the fabric and evaporates instead of making puddles. I found this on my 6 cyl 116 last Summer, when the car was getting horrible gas mileage.

Chucking the car on a lift, I walked around underneath then poked and squeezed a few of the fabric fuel lines, litterally feeling them get wet with fuel.

Cheapest and best fix is to buy about 10-12' of regular American fuel line @ $1.89 per foot, then crawl around underneath and cut'n clamp new rubber fuel line sections in place..... replacing ALL the old fabric stuff whether it looks bad or not.
