Filter Inspection
One of the most common symptoms of fuel issues lies within the filter. Ensure the filter is not clogged or dam-
aged in any way. To check for clogging, safely remove the filter and attempt to blow low pressure air (approx. 3
psi) through the filter with an air compressor. If air does not exit out the opposing side, the filter needs replaced.
Note:
Filters are usually directional. There will be markings that dictate which way it must be installed.
