Cracked, faded vent lines can let carb bowls overflow or suck in dirt, and stock rubber hardens in the heat. CV4 Silicone Vent Tubing, Yellow, 4 mm ID (part SFSVT4-3Y) is pure silicone tubing with a 4 mm inside diameter, rated to 420°F (215°C), for carburetor vents, overflow lines and other low-pressure lines (per CV4). The yellow color adds a custom touch and makes lines easy to trace.

Fitment

Universal. Measure the barb or fitting your line slides onto. Most small carburetor vent fittings take 3 mm or 4 mm ID tubing; the tubing should fit snugly without splitting.

Choose Your Size and Color

3 mm ID fits smaller vent nipples; 4 mm ID fits slightly larger fittings. Colors: red, blue, yellow, orange and green.

How to Install

  1. Let the engine cool completely.
  2. Note how the old line is routed, then remove it.
  3. Cut the new tubing to length with a sharp blade for a square end.
  4. Push it fully onto each fitting.
  5. Route it away from the exhaust, chain and moving parts, and secure it with zip ties.
  6. Run the engine and check for leaks or kinks.

Care Tips

  • Check vent lines for kinks after working on the carb or tank.
  • Keep ends pointed down and away from dirt.
  • Replace lines that are cut, swollen or fuel-soaked.
