3. Install new filters. Tighten until filter is snug
against the gasket, with no side movement.
Rotate an additional 1/2 turn by hand.

CAUTION
Mechanical tightening of the fuel filters is not
recommended and may result in seal and/or
cartridge damage. Tighten the fuel filters by
hand only.

There is a fuel system shut-off valve on the
discharge side of the secondary fuel filter.

4.3 DAVCO FUEL PRO 382
The optional Fuel Pro 382 diesel fuel filter
system consists of a permanently mounted fuel
processor, a replaceable filter element, a filter
element cover and collar and a fluid filter base
assembly. This system is installed between the
fuel tank and the fuel pump and is designed to
be the only fuel filter in the fuel system. The filter
serves as a water separator as well as a fuel
filter (refer to figure 4).
When new, the fuel level as seen through the
clear cover in the 382 filter is very low. It rises as
dirt collects on the filter from the bottom up.
Restriction remains consistently low because
fuel always flows through clean, new media.
Change filter when fuel level reaches the top of
filter element (refer to figure 5).
Filter renewal:
1. Stop engine;
2. Drain fuel by opening the drain valve;
3. Untighten upper collar, remove cover;
4. Replace filter element;
5. Check O-Rings and components for wear;
6. Replace cover, hand tighten collar;
7. Pour fuel up to bottom of filter element
through spin off cap located on top of cover.
8. Start engine, raise rpm for 2-3 minutes, hand
tighten collar again.
