  5. Check tightening condition of ring nut.
    1. Using a caliper with depth gauge, measure the dimension (3 positions) of the ring nut and the top of fuel tank.
    2. Check that the difference between the median value of the measured three positions and the other two positions is within ±1.5 mm (0.059 in).
    CAUTION:
    • If the measured value exceeds the standard, retighten the ring nut to correct erroneous tightening of the ring nut.
    • If the ring nut and fuel pump gasket are deformed, cracked or damaged, replace them with new parts.
