Signs this part needs replacing

  • Perished, hardened or deformed gasket material at the hatch face
  • The dip tube is blocked, corroded or detached, giving unreliable level readings
  • The hatch plate or studs are corroded, seized or damaged
  • Difficulty achieving a sound seal after the hatch has been removed and refitted

Before you order
