Checking Pump Noise!

NOTE: Each AirDog

has been manufactured in a Quality Controlled process and wet tested

for operation and performance before shipment. This is a very quiet and smooth running
system. However, if any fuel fitting on the vacuum side, between the fuel tank and the
AirDog

or the pre-filter, has been left loose during the installation process, the system may

suck air at an excessive rate and will be very noisy. To check for this problem, unscrew the
pre-filter 3 or 4 full turns and activate the AirDog

by turning the ignition switch to on. If the

AirDog

runs quietly, then excessive air from a loose fitting or leaking pre-filter seal is most

likely the reason for the excessive noise. Correct as necessary.

The seal groove in the 3” water separator is a snug fit and on occasion the seal has

been found to not be fully seated. Remove the pre-filter; remove the seal from the top of

the nut plate. Clean and lubricate the seal groove. Carefully replace the seal in the

groove. Be sure to fully seat the seal.

Check all fittings, especially the quick connect at the tank.

Section 8 Fuel Filter & Water Separator

Filter Service Recommendations

Plugging of either the fuel filter or the water separator itself will cause low fuel pressure
and low flow to the engine. If a low fuel pressure issue exists, replace the fuel filter.
