All;

Been chasing mediocre performance in my california-spec 1985 300TD, and have identified and corrected a leaking primer pump earlier today (replaced the old white pump with the Bosch upgrade). Previously I replaced primary and secondary fuel filters.

Following today's primer pump replacement, I noticed I was getting air bubbles into the primary filter.

Put the car up an ramps, and could immediately see fuel leaking from the supply line back at the fuel tank.

I can readily see that these "soft" lines are rubber encased in a braid. Not certain that Advance Auto or AutoZone will have lines like this, can I use plain rubber fuel line to replace the leaking lines? I would think they are braided for a reason, but perhaps not?

Anyone know right off with the appropriate ID is?

Thanks in advance,
Dave

5/16" lines should fit fine and work for years. make sure you use Fuel lines, not vacume or heater hose lines.

Rubber fuel lines fine, DO NOT use bio-diesel, as is corrosive to rubber.

Or use OEM lines (or Viton) and DO use biodiesel, a superior fuel.
