Make sure all fittings are tight and bubbles are
present in alcohol when compressor is compressing air.
Refer to Trouble Shooting Guide if evaporator assembly
is not operating properly.

equipped); clean all parts, replacing all gaskets and
Always use the filler plug on AE-1 evaporator.
Frequent removal of alcohol reservoir will cause
possible deterioration of gasket which will allow
leakage and affect performance.
Fill reservoir 2/3 full. Be certain proper alcohol is
DISASSEMBLY, CLEANING AND INSPECTION,
Carefully disassemble, noting order of removal
Wash all metal parts in solvent; wipe all rubber
Inspect all parts and replace all parts not
Assemble parts, making sure new gaskets and
rubber parts are properly installed.
TESTING FOR SERVICABILITY
With compressor in compressing cycle, bubbles
should be evident in alcohol. If air bubbles are not
present, check Trouble Shooting Guide.
INSTALLATION OF ALCOHOL EVAPORATOR KITS
Installation of alcohol evaporator on vehicles in the
field is a common practice and is easily accomplished.
However, complaints of inoperative alcohol evaporators
or excessive use of alcohol can usually be traced to
either the wrong kit being installed or an incorrect in-
stallation of the proper kit. Therefore, the selection and
installation of the correct kit is important. All field
installation kits have installation instructions; however,
the following information may be helpful.
There are four different types of alcohol evaporator
kits and it is very important the correct kit is installed.
Before selecting the alcohol evaporator kit, you must first
determine the type compressor and the method of air
induction to the compressor. After this determination
has been made, the alcohol evaporator kit can be
selected from one of the following four types:
The Tu-Flo 501 air compressor will use the same
installation in all cases as the Tu-Flo 500 air compressor.
Standard Kit (Fig. 5)
This kit is used where the compressor utilizes its own
strainer and piping consists of a single 4.76 mm (3/16")
O.D. copper tubing line run from the top of the alcohol
evaporator to the adapter mounted between the strainer
and compressor inlet.
Fig. 5 Standard Kit (AE-1 Alcohol Evaporator Illustrated)
Engine Air Cleaner Induction
(Fig. 6 and Fig. 71
This kit is used when the compressor inlet is connected
to the engine air cleaner on the engine intake manifold
and the engine is naturally aspirated (not supercharged
or turbocharged). A single check valve "A" is employed in
this installation and depending on evaporator used may
be connected directly to the evaporator (as shown) or
instructions). Note line "B" is connected to the unloader
port of the governor. When the compressor is unloaded
(not compressing air), the air pressure in line "B" holds
the check valve "A" closed and prohibits alcohol from
being drawn into line "C" thus stopping any possible flow
of alcohol from the jar into the engine intake.
