Sealing a fuel line connection is a fairly straightforward process that requires the right products. Before purchasing any sealant, make sure that it is recommended for that particular type of fuel line and material. Some sealants are not good for plastic or rubber. Some sealants are useful for multiple fittings, including hydraulic, pneumatic and fuel lines.

  1. Prepare the fittings
  2. Double-check that the two fittings use the same thread type for a proper connection. Clean the two connections and dry with an application of surface prep activator.

  3. Apply the sealant
  4. Place some of the sealant onto the threads of the male fitting. Leave the first thread free of sealant. Do not apply sealant to all of the thread turns. This only creates excess that may drip out the ends when connected.

  5. Make the connection
  6. Screw the male fitting into the female fitting. Tighten with a wrench to the recommended torque for that fitting type. Wipe away any excess that drips out.
