Snow Performance SNO-40900 Extreme Environment 300 PSI UHO Water-Methanol Pump

Vehicle Fitment

• Universal Fitment - Direct replacement or upgrade pump for all Snow Performance water-methanol injection systems using standard 1/4 in. high-temperature nylon push-connect tubing, including Stage 1, Stage 2, Stage 2.5, Stage 3, and Stage 4 nylon-line kit variants

Fitment Notes

• SNO-40900 is the nylon push-connect fitting variant - designed for Snow Performance systems plumbed with standard 1/4 in. high-temp nylon quick-connect tubing; not intended for braided line systems
• For Snow Performance systems using 4AN stainless steel braided line, the correct replacement pump is SNO-40900-BRD (includes 3/8 in. NPT to 4AN adapters)
• For systems using 3/8 in. NPT quick-connect fittings, see SNO-40900-QC
• Compatible as a direct drop-in replacement for the factory-installed pump in any Snow Performance Stage 1, 2, 2.5, 3, or 4 nylon-line system, or as a standalone pump upgrade when building a custom water-methanol installation
• Not CARB approved - cannot be legally sold or used in California
• Sold individually (pump only)

Features

• Extreme Environment 300 PSI Ultra High Output (UHO) design - the only OEM-approved water-methanol injection pump on the market, engineered for continuous duty in harsh underhood environments
• Dual EPDM seals allow higher sustained PSI ratings to be achieved safely and for longer service life compared to single-seal pump designs; EPDM material is 100% methanol-resistant and chemically compatible with all water-methanol ratios up to straight methanol
• Proprietary internal wiring design delivers lower amperage draw than visually similar competing pumps, reducing electrical load on the vehicle's charging system and extending relay and fuse life
• Built-in thermal breaker allows the pump to run continuously under sustained demand without overheating or damaging pump internals - a critical feature for track and high-boost street applications where injection is active for extended periods
• Proprietary heat flange and twin-seal design keep motor internals cooler and better protected from heat soak compared to standard pump-sleeve designs used by competitors
• O-Ring sealed and potted connections prevent moisture intrusion into pump internals - a major long-term reliability advantage over competing pumps that use sleeve-style housings that trap moisture and accelerate corrosion
• Every pump is individually tested at the Snow Performance facility before shipping to ensure it meets rated pressure and flow specifications
• 3/8 in. NPT inlet and outlet ports provide high-flow fluid delivery with minimal restriction at rated pressure
• Mounting bracket included for secure, vibration-resistant engine bay installation in horizontal or vertical orientation

Product Description

The Snow Performance SNO-40900 is the Extreme Environment 300 PSI Ultra High Output water-methanol injection pump configured for Snow Performance systems using standard 1/4 in. high-temperature nylon push-connect tubing. It serves as a direct drop-in replacement for the factory-installed pump in any Snow Performance Stage 1, Stage 2, Stage 2.5, Stage 3, or Stage 4 nylon-line injection system, and is also used as a standalone pump upgrade for custom water-methanol builds requiring a proven, high-pressure pump. Every SNO-40900 is individually tested at the Snow Performance manufacturing facility before leaving the factory to verify it meets its rated 300 PSI output and flow specifications - something Snow Performance notes that visually similar competing pumps do not offer.

The pump's engineering sets it apart from lower-cost alternatives in several key ways. Dual EPDM seals replace the single-seal design found in most competing pumps, enabling higher sustained pressure ratings with improved longevity - and EPDM's inherent methanol resistance ensures the seals will not degrade regardless of the water-methanol ratio being used. Proprietary internal wiring reduces amperage draw compared to similarly-sized competing pumps, lowering the electrical load on relays, fuses, and the vehicle's charging system over long-term use. A built-in thermal breaker prevents pump burnout during extended continuous operation - an important distinction for track use or sustained high-boost street driving where injection may be active for prolonged periods. The pump housing uses O-Ring connections that are sealed and potted at the factory, preventing moisture from migrating into the motor internals - a common failure point on sleeve-style competitor pumps.

The SNO-40900 ships with two 3/8 in. NPT push-connect fittings for direct integration with Snow Performance's standard nylon-line systems, along with a mounting bracket for secure engine bay installation. Owners of Snow Performance systems using 4AN stainless steel braided line should instead select SNO-40900-BRD, which ships with 3/8 in. NPT to 4AN adapter fittings for direct braided-line compatibility. Compatible add-on accessories for this pump include SNO-40040, SNO-40060, SNO-38FIL, and SNO-19110. The SNO-40900 is manufactured in the United States and backed by Snow Performance's 90-day parts warranty.
