Weber Genesis II E-310 burner tubes

Three GS4 mains (OEM 67489 LP / 67491 NG class). Same 300-series tubes as E-315; no side sear. Confirm Genesis II, not original Genesis.

Clean versus clogged burner ports Left tube shows even open ports and a blue flame sketch. Right tube shows grease-clogged ports and a yellow uneven flame. BURNER TUBE · PORTS CLEAN Even blue cones. Every port open. CLOGGED Grease in the holes. Yellow, lift, dead spots. Ream with a bit smaller than the port. Do not drill oversized. Brass brush the row. Keep liquid out of the venturi / inlet. If the tube wall is lace under the ports, replace the set — do not patch holes.

Genesis II E-310 is three GS4 mains in the 300 box — Weber lists 67489 (LP) / 67491 (NG) as the three-tube kits on many 2017+ schematics. There is no side sear (that is E-330/E-335). Spirit 18” 69787 tubes are short. Original Genesis (no “II”) is a different cook box.

Bars: E-310 flavorizers. Ignition: E-310 igniter. Sibling sear model: E-335 tubes. Hub: Genesis guides.

Safety

Procedure

  1. Photograph the plate (Genesis II E-310 / S-310), three inlets, and any electrode brackets.
  2. Grates and five ~17.1” bars out.
  3. Release rear clamps. Lift rear, slide off orifices. Label left / middle / right.
  4. Sky-check each tube. Port clog only: clean ports. Extra holes or split seam: replace.
  5. Dry-fit three 67489-class mains. Inlet fully on brass; rear tabs land without bowing the tube.
  6. Clip the crossover / carryover so all three light from the left. A Spirit crossover is the wrong length.
  7. Electrode gap at the factory tab. Bars over ports. Grates on.
  8. Tank on slowly. Soap every joint. Lid open. Light left, walk middle and right.

FAQ

Do Genesis II E-310 tubes fit an E-315?

Main tubes are the same 300 GS4 family (67489/67491 class). Confirm fuel (LP vs NG) and the year on the plate. E-315 still has no sear.

Why search-only for tubes?

No live ASIN pinned specifically as Weber 67489 on this page. Flavorizer bars for the same box may be pinned elsewhere; tubes stay search until a listing title matches.

Replace Char-Broil burner tubes

Pull stamped Char-Broil tubes, match length and inlet, reseat on the orifices, and leak-check. Universal tubes that are short are how flashbacks start.

Replace Char-Broil heat plates

Measure tent length and width on Performance and Commercial carts. Heat plates are the drip shields — when they lace, burners die. Do not buy by lid name alone.
