Water / Alcohol / Methanol Injection Parts List
Here are all of the parts that you'll need to build this system. As you'll see this kit is modular and allows for different pump,
nozzle and tank options depending on your needs. Also, I've done my best to make the items on this list affordable and easy to find. NOTE: Some of these items may be found on Ebay. Beware as
I've heard that there are many low quality/knockoff parts lurking about.
This system is very similar to the vendor kits out there, and will give you the same if not better results at a fraction of the price! Plus, it really is a fun and easy do it
yourself project that will reward you with many years of extra horsepower. I get loads of emails from folks telling me how simple the kit was to install and how incredible the
performance gains are, so I'm sure you'll have the same experience. Tell me about your experience by

| Spray Nozzle Options
There have been many new purpose built spray nozzles available in the last few years. Below are two types that I've had very good results with. The main
difference between the two types below is cost and ease of install. The McMaster-Carr nozzles are inexpensive, perform well, but require more fittings to install. The CoolingMist fittings are 6 times
the cost of a McMaster-Carr unit, but are easier to install and are great performers. If you're unsure on the best nozzle size for you, start smaller and work your way up.

Sized from 1.3-12gph. Great quality with fewer fittings to install than the McMaster-Carr units. Pricey if you are unsure of what nozzle size
you need though. Thankfully, they provide detailed flow data for each nozzle on their website. |

| Water Solenoid |
McMaster Carr |
@$42.50 |
P/N# 7876K12 Route after the pump, before the nozzle. Assures that NO water will be sucked in until the switch activates and opens the solenoid. If you want
a less expensive option, you can use a simple checkvalve. They can be found on the McMaster Carr website, from water injection vendors, as well as other sources. I am not including any additional
information on checkvalves since I have no personal experience with them. |

Napa Auto Parts |

P/N# 701-1575 This switch IS adjustable! Pop off the rubber cap on one end and adjust away! As an alternative, you can use electrical pressure
switches. I've only used the hobbs switch above, so make sure you get a good, quality part if going this route. |

| Water/Alcohol Tank. |
I've used the stock washer fluid reservoir in many cars since it's a decent size and already mounted in the engine bay.
Another inexpensive option is the coolant overflow jugs found at most parts stores. Many vendors offer great methanol compatable tanks and
Last but not least, you can go to your local
"U-pull-it" salvage yard and find a nice jug out of an 80's import that will work perfectly. Price? $5.00-$15.00
Either way, insert a 3/8" fitting into the tank for free flow to the pump. Don't forget to use silicone on the threads of the
fitting.
