(n) If leakage is suspected (manometer level or pressure readings drop), apply soapy water to
the area in question and inspect for bubbles.
WARNING:
If the fuel system leaks, release all pressure from the system before
removing the fuel filler caps. Never attempt to remove the fuel filler
cap with pressure in the fuel system. Never remove the fuel filler cap
when a soapy water solution is present or contamination of the fuel
system could occur.
Note: Inspect fuel tank seams, fuel lines, hoses, caps, connections, collector tank
seams and fittings, and all other fuel related areas for leakage with soapy
water.

the stem, cap must be replaced.
Note: Minor fuel cap leaks may be stopped by turning the nut on the fuel cap
clockwise to apply more tension on the stem o-ring.
(p) If either tank leaks, release all pressure from the fuel system. Repair fuel tank as required.
