Our 19 year old Weber Genesis 1000 LX grill had no gas flow through the manifold from the full propane tank. We tried replacing just the fuel regulator first and that did not work.

We followed the directions in the owner\'s manual to remove the old spider guards, manifold and ignition assembly, which was very easy...just a few screws and than just installed the new manifold which had the fuel tank regulator already attached, snapped the spider guards over the valves and popped in the little ignition assembly. We wer e very pleased that for less than $100 a 19 year old Weber grill was back in working order. Saved a ton of money over the cost of a new Weber grill of comparable quality.
