What happens if my water-methanol pump fails with this switch installed?

If your water-methanol system isn't making proper pressure due to a failed pump, broken line, or other issue, this switch will detect it. The included LED will alert you to the problem, and you can also wire it to your EFI or boost controller to automatically cut boost or retard timing.

What is the adjustable pressure range for this safety switch?

The pressure switch included in this kit is user-adjustable and can be set to activate anywhere between 35 and 100 PSI.

What components are included in this kit?

This kit includes a user-adjustable pressure safety switch, a Snow Performance Water Methanol pressure gauge, a high-intensity LED alert light, and an inline adapter manifold for -4AN lines.

Product Details

This kit gives you a low-pressure safety switch for your water-methanol system, designed to alert you if things aren't working right. You get a user-adjustable pressure switch that can be set anywhere between 35 and 100 PSI, a gauge to monitor your water-methanol pressure, a bright LED light to let you know there's an issue, and an inline adapter manifold for -4AN lines. It's a smart way to make sure your system is actually spraying when it's supposed to.

The main job of this switch is to watch the pressure between your pump and the nozzles. If the pump fails, a line breaks, or anything else stops the system from building proper pressure, this switch will catch it. The included LED light will immediately let you know there's a problem, so you don't keep running your engine without the cooling and octane benefits of water-methanol injection. Plus, you can wire this switch into your EFI system or boost controller to automatically pull boost or retard timing if pressure drops, adding another layer of protection for your engine.
