DevilsOwn Injection
How the DevilsOwn™ Base
Alcohol Injection System works:
The DevilsOwn™Alcohol Injection System begins with a connection to a
supply tank containing a methanol/water mixture. We recommend
DevilsOwn Brew for use with our products. This mixture is pumped at high
pressure through the tubing to the nozzle holder. The amount of alcohol
and water that is injected through the nozzle is easily adjusted by means of
metering the nozzle.
The DevilsOwn™Alcohol Injection System is designed to work as a
bolt-on kit for stock or mildly modified vehicle. A mildly modified vehicle
includes those with header upgrades, exhaust upgrades, air filter kits, etc. If
major engine modifications have been performed a dual nozzle upgrade
may be required for safe alcohol system operation. Major engine
modifications would include larger turbochargers, superchargers,
aftermarket cylinder heads, head porting, camshafts, intake manifolds, etc.

Read this pre-installation guide before installing kit.
Not doing so can cause damage to this
product or your vehicle.
Work safely. Always wear eye protection and gloves when working with lines
or hoses that contain pressurized alcohol or fuel. Never transport alcohol
tanks loose in a trunk, in the back of a pick-up truck, especially NOT within a
vehicle’s interior whether the tank is full OR empty. Always disconnect the
GROUND side of the battery when working on any electrical components.
Alcohol Injection won’t fix problems you already have. Before you install
your alcohol system, be sure your engine is in good mechanical condition.
Intermittent wiring problems, etc., can lead to erratic system performance and
possible engine damage.
DO NOT use Teflon sealing tape on any fittings in a DevilsOwn™ Alcohol
Injection System. It is easyfor Teflon tape to get pulled into the system causing
blockages that can ultimately lead to incorrect alcohol system performance and
potentially engine damage. Only use liquid thread sealer for all NPT type
fittings if not already applied.
DO NOT attempt to start your engine if alcoholhas been accidentally injected
into the enginewhile it was not running. If this occurs, disable all of the
ignition coils by unplugging the leads going to them. Push the accelerator
pedal to widely open throttle and hold it there. While engaging the starter,
turn over the engine for several seconds to clear the alcohol from the engine,
then reconnect the coils. Failure to do this before attempting to restart the
engine could lead to a dangerous intake system backfire.
Never defeat operation of the pump’s pressure switch: It is required for
proper pump pressure output. Never bypass, drill, machine, shim, deform,
scratch, drop, or modify a pump’s pressure switch in ANY way whatsoever!
DO NOT PUMP FLAMMABLE LIQUIDS
DO NOT PUMP MORE THAN 50/50 MIX OF ALCOHOL AND WATER
MORE THAN 50% ALCOHOL IS A FLAMMABLE LIQUID

Quick Start Guide and Checklist
Fluid Tank
❑Remove factory washer fluid tank
❑Drill 7/8" hole in tank and install supplied self sealing bulkhead
❑Reinstall fluid tank
Pump

Section 1: Fluid Bottle
Figure 1: Tank Placement
Remove the factory washer fluid tank from the car, if possible, for ease of
access. On a flat side of the tank, locate a place for the self sealing
bulkhead fitting that is free of obstructions. (The best and recommended
spot is either the side or the front of the tank.) Using a 7/8" drill bit, drill a
hole in a flat location and simply place it in and hand tighten. In order to
maintain a leak-free seal, this must be done on a flat area. DO NOT
place the tank tap in the seam line of the tank. Doing so can cause leaks.
Screw in the tank tap fitting (clockwise) until it is flush with the washer
fluid tank. NO tools are needed to install. DO NOT use any tools to
tighten.
Regardless of where the tank is mounted (under hood, in trunk, etc.), we
recommend mounting the pump near the tank. DevilsOwn pumps are
pusher type pumps and they work best when placed as close to the tank as
possible.

Section 2: Pump Installation
Figure 2: Pump placement
The DevilsOwn pump should be mounted below and as close to the
reservoir (tank) as possible using four of the #10 × 1½" screws. Make
sure to mount the pump away from heat, moisture and road debris.
Because the pump will work at any angle, installation angle does not
matter. Notice on top of the black pump housing, there are two arrows
indicating the direction of fluid flow to and from the pump. The port with
an arrow pointing towards the pump housing is the pump inlet (suction)
from the reservoir. The port with an arrow pointing away from the pump
housing is the pump outlet (pressure).
Find a good place on the chassis to attach the pump’s ground wire. Any
good chassis ground or any solid metal place that is free from paint or
coatings will suffice. (Note the position of the ground bolt in Figure 2,
directly to the right of the pump.) Firmly crimp the ring terminal to the
black wire and fasten the ring terminal to the ground location chosen.

Section 3: Nozzle Selection
Start with the lowest nozzle setting and work your way up. This ensures if
you have any tuning issues to work out on your vehicle, they will get sorted
out using a smaller amount of alcohol and will therefore be less likely to
cause engine damage. Once the car works well on the smaller amount,
then it will be safer to step up your alcohol kit horsepower.
It is possible that while during driving, the vehicle will experience engine
bucking. This bucking is caused by either too much fluid being injected or
not enough air to accommodate what is being injected. To remedy the
problem, do one of the following.
1. Adjust the start position to inject at a higher boost level.
2. Adjust the full position to inject at a higher boost level.
3. Use a smaller injection nozzle.

Section 4: Nozzle Installation
DevilsOwn strongly advises placing the nozzle AFTER the Mass Air
sensor and/or an air-to-air intercooler if so equipped and if possible.
On most turbocharged or CSC applications, DevilsOwn users place the
nozzle in the outlet of the intercooler. If no intercooler is present, the
nozzle can be placed in any accessible location before the throttle body.
This will not damage supercharged applications with a liquid heat
exchanger in the manifold. On these applications, it is recommended to
put the nozzle a few inches in front of the throttle body or after it in a
spacer. Remember, every car is different!
If possible, remove the component where the nozzle is to be installed
from the engine. Be careful not to damage your engine during parts
removal. Using an 11/32” drill bit, drill a hole at the selected location. If
drilling through thicker metal like a throttle body or an intake manifold,
use a 1/8” NPT tap. If going through thinner material the nozzle can
sometimes just thread right into it. Alternatively, you can have a 1/8”
NPT bung welded in at any exhaust shop. If running dual nozzles this
step will need to be repeated.
Before placing the nozzle into the intake be sure to tighten the filter. Do
not over tighten this filter screen to the nozzle housing as this will cause
reduced flow from the nozzle. The filter side is the inlet side of the nozzle
and the side with the small hole is the spraying side. Like before, the
nozzle should turn by hand 1/2 way, then only need another 1-2 turns
with a wrench to achieve a leak free seal. It is normal for the nozzle not
to always seat the O-ring the first time it is put in. Every time it is
loosened and tightened it will naturally tighten further.

Section 5: Tubing
Run the tubing from the tank to the pump, leaving the excess at the tank.
Be sure to keep the tubing clear of hot areas and moving parts that could
damage the hose. Mark the hose at the desired length with a few inches
of slack and cut the hose, making sure the ends are cut squarely. If the
ends are burred you can clean them up with a file.
Slide the tubing into the push-to-connect on the pump and then into the
tank. With the push-to-connect used on the DevilsOwn pumps, the
tubing can be easily removed by pressing in on the sleeve and lightly
pulling on the tubing.
Run the tubing from the pump to the nozzle leaving the excess at the
nozzle. Attach the check valve to the black 90onozzle holder using the
9/16" wrench. Attach the nozzle holder assembly to the nozzle. Finally,
cut the tubing with a few inches of slack and slide the tubing into the
check valve.
