2. Check fuel pressure

  1. Prepare for inspection.
  1.  Purchase a new fuel tube, and take out the fuel tube connector from its tube.

Hint

: part no. 23901–0D010

  1.  work for prevent gasoline from spilling out.

     

  2.  disconnect the efi fuel pipe clamp.
  3.  disconnect the fuel tube from the fuel main tube.

     

  1. Install sst (pressure gauge) as shown in the illustration by using the sst and fuel tube connector.

    Sst 09268–41047 (90467–13001, 95336–08070), 09268–45014 (09268–41200, 09268–41220, 09268–41250, 90467–13001)

  2.  wipe off any splattered gasoline.
  3. ) start the engine.
  4.  measure the fuel pressure at idle.

    Fuel pressure: 304 – 343 kpa (3.1 – 3.5 Kgfvcm2, 44 – 50 psi)

  5.  stop the engine.
  6.  check that the fuel pressure remains as specified for 5 minutes after the engine has stopped.

    Fuel pressure:
    147 kpa (1.5 Kgfvcm2, 21 psi) or more
