Primary Fuel Filter
Primary Fuel Filter Element#: R080033
To Drain Contaminants:
Draining the collection bowl: water is heavier than fuel
and will settle to the bottom of the bowl and appear
different in color. In extremely humid conditions, take
a fuel sample (in a clear container) frequently, daily, if
needed and drain as required if water is present.
1. Place a suitable container below the unit to collect the
contaminants.
2. Close the fuel tank valve (if applicable), then loosen/
remove the drain plug (1) at the bottom of the bowl.
Figure 11-16 item 1.
3. Prime the fuel system following the instructions under
Priming the Fuel System.
To Replace the Element:
Element replacement frequency is determined by the
contamination level in fuels. Fuel fl ow to the engine
becomes restricted as the element slowly plugs with
contaminants, resulting in noticeable power loss and/or
hard starting. Replace element annually, or every 50
hours, whichever comes fi rst. Change the element
as soon as possible. Always carry extra replacement
elements as one tank full of excessively contaminated
fuel can plug a fuel fi lter.
Clean any debris or dirt away from the Crusader head/
fi lter joint prior to removal.
1. Place a suitable container below the unit to collect the
contaminants.
2. Close the valve at the fuel tank (if applicable) and
then remove the drain plug (1) to empty the fi lter of
fuel.
3. Spin the Element and Bowl off together (use a strap
wrench on the element), then remove the bowl from
the element (2). Figure 11-16 item 2.
4. Clean the bowl O-ring gland and the sealing surface
of the mounting head free of dirt, debris or gums.
5. Apply clean motor oil to the new seal and to the bowl

O-ring supplied with the new element.
6. Place the new seal onto the top of the new element
and the O-ring into the bowl gland.
7. Spin the bowl onto the element, and then fi ll the
element and bowl assembly with clean fuel.
