Water Meth Components

A typical system has a reservoir to hold the fluid, a pump to pressurize it, a controller to decide when and how much to inject, lines and fittings to carry it, a check valve or solenoid to stop siphoning, a filter to protect the nozzle, and one or more nozzles to atomize the spray. Many systems also add a level sensor or flow sensor for failsafe protection.

• Pumps. The pump sets the system's pressure and flow capacity. Replacement pumps restore a failed system; higher capacity pumps support larger nozzles or multi-nozzle setups. Confirm your compatibility with your controller's output and current rating.
• Reservoirs. Larger or remote tanks reduce refill frequency. Check the outlet fitting size and whether the tank supports a level sensor.
• Lines and fittings. Nylon tubing with push-to-connect fittings is common on street set ups and braided lines with AN fittings are common on race builds. Match tubing diameter and fitting type to your existing parts.
• Check valves and solenoids. These keep fluid from siphoning into your engine under vacuum and stop dripping when the system is off. A solenoid adds positive shutoff and quicker response.
• Filters. An inline filter protects the nozzle's small orifice from debris. Filters are a maintenance item and should be cleaned or replaced on the manufacturer's schedule.
• Sensors. Level sensors warn you before the tank runs dry. Flow sensors confirm the system is actually injecting and can feed a failsafe controller.
• For nozzles, plates, and controllers, see the dedicated water meth nozzles, injection plates, and controllers categories.
• How do I make sure a component fits my system?
• Check four things: thread size, tubing size, fitting type, and electrical connector. Brands do not always use the same standards, so a part that works in one system may need adapters in another. When in doubt, match the brand and series of your existing kit.

Repair vs upgrade

If one part has failed, replace it with a matching part to restore the system as designed. If you want more flow, more capacity, or more protection, upgrading the pump, reservoir, or sensors can extend your current system without starting over.

Maintenance tips

Use distilled water and clean methanol, check fluid levels regularly, inspect lines for wear near heat sources, and replace filters on schedule. Make sure all seals, tubing, and thread sealant are methanol compatible.
