Moroso Accumulators, Fittings & Valves
These provide an instantaneous supply of oil when pressure falls
below a safe level. Our professional series are available in 1.5 or 3.0
quart versions. The 1.5 quart version is perfect for Sport Compacts
and other vehicles with 4 and 6 cylinder engines. Ideal for street
performance and mild off-road applications.
All Accumulators store oil under pressure and automatically release
that oil to the main galleries when oil pressure drops. Moroso
Accumulators can also be used to manually pre-lube engines before
starting to prevent cold-start scuffi ng and premature bearing wear.
• Accumulators Protect Against Oil Pressure Loss!
• Automatic Operation!
HOW AN ACCUMULATOR WORKS
The Accumulator is tapped to the pressure side of the engine’s
oiling system. When the engine is running, oil pressure forces oil
into the accumulator and compresses air ahead of it.
Figure 1: Under normal
conditions, oil pressure
keeps a reserve of oil in the
Accumulator under constant
pressure. If oil pressure
should suddenly drop
because of hard acceleration,
severe cornering or hard
braking, air pressure
immediately sends oil back into the engine. When the danger is
over and the pump is once again supplied with oil, pressure in the
engine forces oil back into the Accumulator where it is ready for
the next emergency.
Figure 2: When oil pressure drops,
air pressure sends the stored oil
into the engine at the main oil
galleries to prevent damage.
Three quarts of oil under pressure
provide emergency supply
instantaneously when needed.
Air Pressure gauge verifi es that Accumulator is ready for use.
Cold start valve releases oil into cold engine for reduced wear.
Tapped for 1/2" NPT fi tting.
Can be mounted in any position using Moroso Accumulator Mount.

12 VOLT SOLENOID VALVE ACCUMULATOR FITTINGS
Allows remote control of fl uid fl ow via 12v
switch. Each side of the solenoid valve contains
a 1/2” NPT female port. Solenoid Valve is open
when toggle switch is on, when switched off
remains closed regardless of ignition switch
position. Use the toggle switch and 16 gauge
wire included in the kit to wire the valve. A
20-amp fuse must be used between the power
source and the switch. Use a power source that
is active (i.e., “hot”) only when the ignition
switch is in the “on” position.
CAUTION!: Do not use with any fuels. We have a full range of fi ttings available, these
are the most commonly used for an accumulator
set-up.

SYSTEMS
Once you have installed your New
Moroso Accumulator put 6psi of
air pressure into the cylinder by
using the air valve and reading the
gauge provided on the unit. Once
engine is running you will notice
a pressure increase on the gauge.
The system is now primed and
ready to go.
