B. Attaching the filter mount
1. Survey the engine compartment for possible mounting locations. Solid
structures such as the firewall, fender well, radiator support or frame are
normal locations.
(Do not mount on engine.) See diagrams A and G
2. This filter system must be mounted vertically to operate properly.
3. When the location has been determined, mark the area using the filter
mount as a template and mark the holes with a center punch and hammer.
See diagram B
4. Install adapter fittings (BP-190) on filter mount (BK-305) using PST or
thread tape. Using a
13
⁄
16

wrench, tighten fittings 2-3 turns beyond
finger tight.
5. With a
7

drill bit, drill out the previously marked mounting holes and
attach the filter mount using the
7
⁄
16
⬙
bolts, nuts, small washers and fender
washers provided. The bolts should be tightened to 20 foot pounds.
5

wrenches or socket will be required for this operation.
6. Fill the By-Pass Filter element (EaBP-120) with the same motor oil being
used in the vehicle. Lubricate the filter gasket with oil and spin filter onto
mount. Tighten per instructions on the filter.
C. Oil Supply
1. Locate a pressurized oil port such as a gallery port, pressure sender port,
etc.
Note:
AMSOIL recommends adapting off of the pressurized oil port
using a fitting(s) to accept the
1
⁄
2
⬙
JIC female hose end provided in this
kit. Purchase of adapters for your specific application is required.
2. Measure the amount of hose (BP-250,
Purchased Separately
) needed to
run from the pressurized oil port. Using a utility knife, squarely cut the hose
to the proper length.
3. Install hose fittings (BP-260) on both ends of the hose following the
instructions
noted in diagram F.
Tools required are one
7

8
⬙
and one
15
⁄

wrench or vise.
Note:
The hose and fittings supplied with this kit have been matched to
provide maximum performance and life expectancy. Interchanging with
other types or brands is
not recommended
and
should be avoided.
Should additional hose be required, it may be obtained from AMSOIL by
ordering part number BP-250. Do not use any form of thread sealant any-
where on the BP-260 hose fittings.
4. Route and connect the hose assembly to the filter mount (BK-305) at the
IN
port
see diagram C
and to the
1
⁄
2
⬙
JIC male fitting at the pressurized
oil port, making sure the hose does not contact any hot or moving sur-
faces or sharp edges. Ensure a minimum of a
3
⁄
4
⬙
bend radius is main-
tained at all corners. Also, bends in hose should not begin at hose
fittings.
See diagrams D and H
5. Using two
7
⁄
8
⬙
wrenches, tighten 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.
D. Oil Return
1. The outlet of the by-pass unit (BK-305) should be connected to a low pres-
sure or free oil return to the crankcase or sump of the engine. Many heavy
duty diesels have access ports on the side of the oil pan or at the oil fill
tube.
2. Measure the amount of hose (BP-250,
Purchased Separately
) you will
need to run from the filter mount (BK-305) to the low pressure oil outlet
on the engine.
Note:
AMSOIL recommends adapting off of the crankcase or sump port
using a fitting to accept the

5. Route and connect the hose assembly to the filter mount (BK-305) at the
OUT port
see diagram C
and to the
1

JIC male fitting at the low pres-
sure oil port, making sure the hose does not contact any hot or moving sur-
faces or sharp edges. Ensure a minimum of a

⁄

bend radius is maintained
at all corners. Also, bends in hose should not begin at hose fittings.
6. Using two
7
⁄
8
⬙
wrenches, tighten 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.
7. Use plastic ties (BP-46) to secure hose in position and away from
damage. Trim ties using side cutter.
Note:
Over tightening the plastic ties can restrict oil flow.
5. Record vehicle mileage/operating hours and date of installation.
E. Start up procedures
1. Check that all fittings and hoses are securely attached, and that the
hoses are routed properly.
2. Check engine oil level. Fill to full mark if necessary.
3. Set vehicle parking brake. With transmission in park/neutral start the engine
and immediately check oil pressure.
Note:
Pressure may initially take a
moment or two to rise.
Caution:
Carefully check for leaks at fittings, hoses
and mount. If leaks are observed,
STOP ENGINE IMMEDIATELY,
repair
leaks and continue.
