9. Subtract the second reading from the first reading.
a. If the difference between the two readings is less than or equal to 1.00 kPa, there
is no restriction in the scavenger path. No action is required.
b. If the difference between the two readings is greater than 1.00 kPa, disconnect
the eVap scavenger tubing (blue tubing) and repeat the test.
c. With the scavenger tubing disconnected, if the pressure difference is less than
1.00 kPa, inspect the scavenger tubing for kinks and replace as necessary. If no
kinks or restrictions are noted, inspect the Scavenger Downtube (1407-3904-
000) for restrictions, replace as necessary.
d. If the pressure gradient remains greater than 1.00 kPa, troubleshoot or replace
the eVap.
