Its polypropylene housing resists high methanol concentrations, while the large filtering area ensures minimal flow restriction. Designed for quick installation and easy cleaning, this reusable filter extends pump life and maintains optimal injection system performance. ## Description The AEM Water/Methanol Injection Filter is an in-line filter that uses a micronic mesh screen to filter particulates as small as 40 microns. This allows a cleaner flow of water/methanol to be passed into the engine, not only protecting the internals of the engine itself, but also the working parts of the water/methanol pump too. Run the AEM Water/Methanol Injection Filter in-line before the pump to protect both pump and engine. If you are using a Water/Methanol Injection System it may greatly increase pump life to use a water/methanol filter. The AEM Water/Methanol Injection Filter prevents foreign particles as small as 40 microns from clogging or damaging pumps, injection nozzles check valves or flow sensors. The AEM Water/Methanol Injection Filter uses fittings for use with 1/4inches OD nylon tubing, so it fits most Water/Methanol injection kits on the market today. Review: Awesome filter, easily serviceable - Not sure what other reviewers were expecting, it's a great product! I don't have a filtered bulkhead, nor a filter anywhere in my methanol system. I run ~33 gpm of methanol as my extra fueling in a turbo application. I got a piece of debris stuck in my injector nozzle and it tried to take my motor out running it lean for a brief second. This is a coarse 40 micron filter that would have caught that debris, but it's not such a fine filter that it will impede flow for a high flow application. I've read it's good to flow up to 43 gpm of methanol. It fits snugly in the housing. My filter did not have the AEM logo anywhere on it, nor any logo. Just solid black, which is fine, nobody sponsored me, I don't care to sponsor anyone. Review: Perfect For Water Methanol Injection - So glad I installed this just before my injectors! Before using this I had no idea so much sediment was traveling through the pump and into the engine. Everything about this is simple; installation, checking, and cleaning. The cap simply screws off so you can take it to a sink for rinsing. Most of the sediment gets captured in the part that stays inline but a squirt from a water hose, carb cleaner, WD-40, or even just running the water injection will quickly wash out the sediment. And it attaches with push-lock connectors so if you want to pull the entire assembly, it is quick and easy. This has been installed on a daily driver with a modified 12 valve Cummins for about a year through ambient temperatures ranging by about 100 degrees F. There have never been any leaks. For a while I noticed my water injection was still coming on under boost but hardly using any water. Sure enough, this filter was clogged with mud. After quickly cleaning the filter the water methanol was working again as it should. This is a must have. I ordered in 2018 and received this filter just as it is advertised. ## Features - Simple to install, takes less than a minute - Polypropylene housing-rugged material that is compatible with high concentrations of methanol - Large Filtering Area assure long service life and does not significantly reduce flow - Completely serviceable assembly, can be disassembled, cleaned and reused for a long service life ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0032W3KH8 | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | #385,341 in Automotive ( See Top 100 in Automotive ) #1 in Automotive Performance Fuel Injectors & Parts #2,420 in Automotive Replacement Fuel Injection Products #5,126 in Automotive Replacement Air Filters | | Brand | AEM | | Brand Name | AEM | | Compatible with Vehicle Type | Passenger Car, motorbike | | Customer Reviews | 4.6 out of 5 stars 151 Reviews | | Global Trade Identification Number | 00840879020941 | | Included Components | Water Meth Components | | Item Type Name | Water Meth Components | | Item Weight | 0.09 Kilograms | | Manufacturer | AEM | | Manufacturer Part Number | 30-3003 | | Manufacturer Warranty Description | Manufacturer warranty | | Model Number | 30-3003 | | OEM Equivalent Part Number | 30-3003 | | Outer Material | Stainless Steel | | Product Grade | Replacement Part | | Style | In-Line | | Style Name | In-Line | | UPC | 764885209254 840879020941 | | Unit Count | 1.0 Count | | Vehicle Service Type | Passenger Car, motorbike | ## Product Details - **Brand:** AEM - **Outer Material:** Stainless Steel - **Item Weight:** 0.09 Kilograms - **Style:** In-Line - **Global Trade Identification Number:** 00840879020941 ## Images ![30-3003 Water/Methanol Injection Filter - Image 1](https://m.media-amazon.com/images/I/81QUEb3AckL.jpg) ## Questions & Answers **Q: Where to install. Im not sure where to install it after o before pump. What you recommend to me?? Thanks** A: You can install pre or post pump - just make sure fitting to tank has a built in strainer if placing post pump. **Q: Looking to replace the screw-in push-to-connect fittings. are they 1/8 npt?** A: I am pretty sure they are 1/4 NPT. **Q: Boost juice for 1991 Nissan 300zx twin turbo Z32-D series 5 speed** A: Yes it’ll work **Q: My aem pump is rated at 300psi and this specifically states 150psi max. What’s the deal? Is there a 300psi compatible option?** A: What's your pump part number? This is because the pumps by AEM are rated at 10Amps @200PSI. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Awesome filter, easily serviceable *by D***V on March 8, 2016* Not sure what other reviewers were expecting, it's a great product!
