AIRTIGHTNESS TEST
After reassembly is completed, carry out an airtightness test with the following steps:
1. Install
a
blind plug to the overflow screw opening. Apply air pressure of about 147 kPa (1.5 kgflcm2)
[21.33 psi] from the fuel inlet hole. Insert the pump into the oil until the overflow screw is in the oil, and
check that air does not leak from any part of the pump.
2. Then, apply higher air pressure of about
490
kPa
(5
kgflcm2) [71.1 psi] and check for air leaks from
any part of pump in the same condition.
