Alky Pump install
Important notes… Do Not Mount pump with head facing
upwards as this will allow water to collect inside sleeve and
ruin motor. Please install as pictured, It can also be installed
horizontally as long as the pitch does not allow water to
collect in sleeve.

C5 Corvette installation instructions
1) The tank modification
The windshield washer tank will need to be modified to deliver the fluid to the pump
assembly. The modification entails drilling a ¾ diameter hole in the bottom of the tank,
its lowest rear point, then installing the supplied bulkhead fitting. The fitting will be
installed as follows, the main body of the bulkhead and Teflon washer will be inserted
from the inside of the tank out, then once through, install stat-o-seal washer, then
stainless washer, then nut. Once nut is threaded.. tighten assembly. Some tips for
doing this are, if a small length of wire is fed from inlet to outlet, the fitting can be
slipped on to the wire and guided into place. Once the nut has been started, grabbing
inside of fitting with needle nose pliers to hold the thread, then use a wrench for
tightening the nut down. Lastly an inexpensive ¾ drill bit for making the hole is a
simple spade wood bit available at most hardware stores. Its only plastic. At this point
install 90 degree fitting pointing toward tank. The short length of –6 hose which is 18
inches will be attached at this point. It may be advisable to test the tank for leaks at
this point using water. Next is to drill hole into cap and install supplied vent. Drill a
smaller diameter hole, and press vent in. 3/8 should do it. Next is pull motor from tank
and install the supplied brass tank plug into rubber grommet. Motor can be used with
an external tank available separately. Also replace low level sender grommet with
supplied new one.
2) Pump mounting
Before mounting the pump, install the brass 90 degree fitting on the inlet of the pump,
use the larger of the two fittings provided. The top of the pump will be marked with an
arrow indicating flow direction. Next install the smaller 90 degree brass fitting on the
outlet of the pump. Careful when tightening these fittings as the housing on the pump
can break. Rule of thumb, tighten by hand then one full turn. The mounting location
for the pump will be in the wheel well behind the drivers side front tire. Use the
supplied 4 self tapping screws to attach pump, if drilling into chassis metal, attach oring to one of the bolts before its drilled into place. This will ground it. Now install the
short 18 inch feed hose. Next, on the outlet attach 32 inch section of hose. Pump is to
be mounted with its head pointing down to the ground so access to adjustment screw
can latter be made if needed.
3) Nozzle
The nozzle will be placed before throttle body. Install head of nozzle in the upper
portion of the air bridge 2 o’clock position on Mag cars or in the upper portion of the
pipe on supercharged applications. The installed height of the nozzle must be
higher than the tank. Else siphoning can occur. Simply drill 3/8 diameter hole into
location, feed nozzle in leaving one sealing washer on the inside.. tighten fitting on the
outside , then depending on thickness of material, install other washer on the outside.
Some applications require no washers with thick aluminum or silicone hose installs..
others require just one.. others both.. in the case of thin aluminum. Trick is to not
bottom nozzle out in the 90 degree elbow supplied. After nozzle is installed attach
supplied 1/8 pipe to –4 adapter. Clean area for debris, reinstall pipe. There is a supplied
check valve “IN CASE” siphoning occurs, whereby liquid flows when system is shut off.
4) MAP sensor
The MAP(manifold air pressure) sensor can be installed under the dash if an
aftermarket mechanical gauge is used. Enclosed is a brass “t” and compression
fittings so the plastic line going to the aftermarket gauge can be used. Simply cut
tubing, and place brass block in-line. Then attach small section of hose from brass
barb to nipple on MAP sensor. Enclosed for 5 volt power is a 5 volt regulator. Wire
the regulator RED to Red on 6 pin connector, Black to ground, green to green on 6
pin connector.
5) Under-hood wiring
The only wiring needed to be done under the hood is the pump, and then run shielded
double wire into vehicle through firewall. Two options, one is through the grommet or
drilling a small hose through the fiberglass and using RTV sealant underneath the hood
latch grommet.
Now maybe a good time to take a break, wash hands, the easy part begins.
6) In-Car wiring
This is just guidelines from numerous installations I have done. The sky is the limit on
creativity, and this should only be used as reference for what I have done, has been
easy, and has worked.
The first thing I always do is visually place where the location of the “turn-on” LED will
be located. Typically this will be near your boost gauge. The purpose of this LED is to
indicate when the system has reached its turn-on threshold based on the signal from
