fuel tank and fuel pump module, and tighten the cap.

8. Check for leaks from the installation section of the fuel pump

module by the following procedure.

(1) Apply soapy water to the inside diameter of the cap.
(2) Choke the vapor hose and main hose, apply an internal

pressure of 10 kPa (1.45 psi) or less from the return hose
and check that no bubbles form in the soapy water.
