B. Filter selection
Any one of 8 different size AMSOIL Full-Flow Oil Filters and 3 different AMSOIL By-
Pass Filters may be used with this mount. Select a full-flow filter that is equivalent or
larger than the one originally installed on your vehicle. The larger the filter used, the
greater the filtration capacity and the longer the filter life. The By-Pass filter should be
the largest for which space is available. Use the dimension information below as well
as the data in diagram A to assist you in selecting your filters.

1. Survey the engine compartment for possible mounting locations. The mount should
be located in the same area as the existing full flow filter. Make sure the mounting
structure is adequate to carry the weight of the filtration system.
2. The filter mount can be rotated 180° in its mounting brackets. This allows the oil
supply and return hoses to enter the mount on either the right or left hand side. Choose
the side that will minimize the need for bends in the hoses or the need for additional
hose fittings. Also, refer to diagram B for preferred mounting angle positions.
3. When the location has been determined, use the mounting template provided to locate
and mark mounting holes. This can be easily done with a center punch and hammer.
4. With a
1
⁄
4
drill bit, drill out the previously marked mounting holes and attach the
top mount bracket (BP-194). Use the 4 - 1
long
1
⁄
4
bolts, nuts, small washer and
fender washers provided. Note the assembly diagram D for details. Using two
7
⁄
16
wrenches or socket, tighten to 8 foot pounds.
5. Apply thread sealant onto the two “O” ring adapter fittings (BP-289) as noted in
diagram E. Install fittings in mount end adjacent to the arrows. Using a 1
wrench tighten
to 30 foot pounds. If desired, optional 90° angle fitting (BK-21) or 45° fitting (BK-22)
may be installed at this time. See diagram D.
Do not
use thread sealant on either end
of the angle fittings, tighten to 525-575 inch pounds or from finger tight rotate an
additional 60° or
1
⁄
6
of a turn. Keep in mind the direction you wish to have the hoses
intersect the mount.
6. Apply thread sealant as noted in diagram E to the Allen head “O” ring plug (BP-191).
Using a
5
⁄
16
Allen head wrench, install plug in remaining mount port and tighten
to 30 foot pounds.
Note:
If optional oil sampling valve is to be used, refer to diagram
D and install in place of the Allen head “O” ring plug. Apply thread sealant to the
external threads on all components in the BK-13 kit.
7. Attach the filter mount (BK-309) to the mounting brackets using 4-1
1
⁄
2
long
1
⁄
4
bolts,
nuts and washers provided.
Warning
: The bolts
must
be installed so that the nuts
are on the side opposite the filter nipples. Failure to do this will result in the bolts
hitting the oil filters. Using two
7
⁄
16
wrenches or socket, tighten to 8 foot pounds.
C. Oil Supply
1. Using an oil drain pan to capture lost oil, remove the existing engine full-flow filter.
Clean the gasket seating area on the engine with a lint free cloth.
2. Temporarily assemble the Filter Adapter Kit by sliding the o-ring (BP-346) on to
the adapter nut (BP-405), and then slide the adapter nut into the large center hole
of the spin-on adapter. (BP-420) This can be made easier by applying a small
amount of oil on the o-ring.
3. Thread the Filter Adapter Kit on to the engine and determine the direction in which you
would like the hoses to intersect the adapter. Remove the assembly from the engine.
4. Apply thread sealant, as noted in diagram E one BP-289 and the BP-331 90°
fitting. The sealant should be placed on the o-ring side thread only.
5. If you wish to have the hoses intersect the spin-on adapter perpendicular to its top,
install the BP-289 straight fitting in the adapter nut and the BP-331 90° fitting on the
side of the spin-on adapter, labeled A. Reverse the fitting position if you wish to have
the hoses intersect the spin-on adapter parallel to the top of the spin-on adapter.
6. Using a 1
wrench, tighten BP-289 straight fitting to 30 foot-pounds. Thread the
BP-331 three full turns and position in desired location. Tighten locking nut on
fitting 30 foot-pounds.
7. Apply a thin coating of oil on the spin-on adapter gasket and the adapter nut o-ring.
8. Reassemble adapter and make sure fittings are correctly positioned and tighten
adapter nut to 35 – 40 foot-pounds.
D. Oil feed and return lines
Note:
The hose and hose fittings supplied with this kit have been matched to pro-
vide maximum performance and life expectancy. Interchanging with other types
or bands is
not recommended
and
should be avoided.
Should additional hose be
required, it may be obtained from AMSOIL, Inc. by ordering part number BP-350
by the foot.
1. (Oil supply hose) Measure the amount of hose (BP-350) you will need to run from
the side port on the spin-on adapter (labeled
A
) to the port with arrow pointing
IN
on the filter mount, also labeled
A
. Additional length will be required to accom-
modate engine movement during operation. Also, consider how the hose will be
routed. Make sure the hose does not contact any hot or moving surfaces or sharp
edges. Insure a minimum bend radius of 2
1
⁄
4
is maintained at all corners. Also,
bends in hose should not begin at hose fittings. See diagrams C and H for addi-
tional detail. Note: Insure hose has significant additional length to accommodate
movement of engine. Note the need for optional 90° fitting.
2. Using a fine tooth hacksaw or utility knife, squarely cut the hose to the proper length.
3. Install hose fittings (BP-360) on both ends of the cut hose. Follow the instructions
noted in diagram G. Tools required are one 1
wrench and one 1
1
⁄
16
wrench or vise.
Note: Do not use any form of thread sealant anywhere on the BP-360 hose fittings.
4. Route the hose assembly as noted in D.1. and connect the hose fittings. Optional
90° fitting (BK-21) or (BK-22) 45° fittings may be installed at this time between
the hose fitting and mount or spin-on adapter.
5. Using two 1
wrenches, tighten the hose fitting swivel nuts to 525 – 575 inch-
pounds or from finger tight, rotate an additional 60° or
1
⁄
6
of a turn.
Note:
Do not
use any form of thread sealant anywhere on the hose fittings.
6. (Oil return hose) Repeat steps D.1 through D.5. Connect hose at the center port
on the spin-on adapter, labeled
B
and the port with the arrow point
Out
, on the
filter mount, labeled
B
.
