Holley 557-101 EFI Water/Methanol Injection System Installation Kit

This system is designed for use with Holley HP and Dominator EFI systems. It is not a stand-alone system. The components are
designed for 100% water and up to a 50/50 percent mixture of water and methanol. Windshield washer fluid is commonly used. Do NOT use more than 50% methanol in the mixture, or damage to components may result.

Note:

• If you use other hardware in the installation of this system, it must be compatible with the fluid you use. Brass, aluminum, steel, natural rubber, and silicone are not suitable for use with a water/methanol mix and should not be used.
• The solenoids must be driven by an ECU injector driver output. If an extra inject or driver channel is not available, a PWM
  output can be used to trigger Holley PN 554-115. This is a two channel injector driver device that can control two water meth solenoids using two high (+) or low (-) side PWM outputs.
  

Parts Required:
This kit is an installation kit only. A pump and solenoid(s) are required as well. Note that you must use Holley solenoids for proper
operation in conjunction with HP and Dominator EFI systems. The system is set up to allow up to two solenoids to be controlled.
These parts are offered by Holley in the following PN's:

557-100 - Pump. This is not an "off the shelf agricultural pump". It is designed for water/methanol injection.
