M969 and M969A1. These models are 5000 gallon
fuel dispensing semitrailers used primarily for automotive
refueling. These models can also be used for overwing
aircraft refueling. The M969 and M969A1 have the same
bulk delivery and self-load capabilities as the M967 and
M967A1. Additional equipment includes a filter/
separator and dual dispensing system. Each dispensing
system includes a meter. hose reel with electric rewind

-inch dispensing hose, and a dispensing
nozzle. Flow rate for metered delivery of fuel (gasoline or
diesel) is up to 60 gpm-through one nozzle only, or
through both nozzles at the same time.
c. M970 and M970A1. These models are 5000 gallon
fuel dispensing semitrailer designed for under/overwing
refueling of aircraft. They use the same engine as the
M967, M967A1, M969, and M969A1, but have a 3-inch
high pressure centrifugal pump. Additional equipment
includes a filter/separator, recirculation system, and two
refueling systems-one each for undewing and overwing
servicing.
(1)
Recirculation System.
This system provides
fuel sampling and complete recirculation of fuel through
the filtering and dispensing system to remove
condensation and contamination.
(2)
Underwing Refueling System.
This system
includes 50-feet of

hose, electric-rewind hose
reel, single point dispensing
nozzle,
breakaway fitting on
the hose reel, and deadman control.
(3)
Overwing Refueling System.
This assembly is
part of the above assembly and includes these additional
components: 50-feet of 1

dispensing nozzle, and hose reel with electric-rewind. A
small closed-circuit dispensing nozzle (interchangeable
with the ovenwing nozzle) is also provided for underwing
(helicopter) refueling.

Upgrades to M967, M969,
M970. A new fuel
dispensing nozzle, hose trough cover, control panel cover,
rear ladder. front and rear drain, and tachometer and lead
assembly have been introduced for
repairing
or upgradeing
these three models. A new hose reel cabinet door has
been introduced for upgrading model M969.
e.
M967A1, M969A1, M970A1 including M970 SNTC-
0843, TC-0844, and TC-103 thru TC-178.
These models are
the same as models M967, M969, and M970, except for an
elastomeric-type drive coupling between the fuel dispensing
pump and the engine assembly. A new axle, bogie, and
braking system with a “S’’-type cam brake actuating
mechanism have been installed on these models.
f. M970 (Marine Corps).
These models, built under
Contract Numbers DAAE07-85-C-J044 and DAAE07-89-
C-J020, have incorporated the M970A1 dispensing pump,
pump coupling, and control panel cover. These items are
called out in the repair parts and special tools list figures 113,
116 and 1.
During vehicle production, the following kits have
been installed to the M970 Marine Corps vehicle:
(1) Defueling Kit (Modification Kit. Engine
Accessories). NSN 2910-01-093-7965, Part Number AE20074-
008, GAGE 00624.

These models (SN TC 0843,
TC-0844, and TC-103 thru TC-178) built under contract number
DAAE07-C-89-J020 have incoraporated the M970A1 dolly.
The affected are noted in the repair parts and special tools list.
1-9. Vapor Recovery Kit
a
Description.
The system consists of vaportight tine
running from a sealed hood on the emergency valve vent
(directly behind manhole cover) to the tear of the tank. The
rollover rail on the roadside of the semitrailer is used as part of
the line. The adapter on the end of the lines in compatible with
the 4-inch quick disconnect vapor recovery connections at a
majority of fuel depots.
b.
Use.
The vapor recovesy system can be installed on all
models and is required in certain ecological areas.
(1) The system allows after a fuel depot to collector recover
the vapors and gases that are present during the loading
operations.
(2) Vapors and gases can also be cycled back to the
semitrailer through the recovery system during unloading
operations.
