New Gas Line

While researching possible causes of my fuel delivery issue, I read that the old BMW cloth-covered lines are porous and can start to suck air when they age. All the lines in my car are relatively new, with the exception of the hose from the fuel tank to the hard line under the rear firewall. The old hose looked pretty bad once removed from the trunk of the car (after I disconnected the battery - better safe than sorry).

I replaced it with a $4 piece of hose from NAPA.

I swear the car starts faster and feels like the fuel pump is working more efficiently but perhaps I'm imagining the extent of the benefit. The true test will come when the fuel level drops below half a tank. We'll see if we "run out of gas" again.
