2340-11790 Diesel Fuel Filter Water Separator The 2340-11790 fuel water separator filter is a premium aftermarket replacement filter engineered exclusively for Hino heavy-duty truck diesel engine fuel systems. As a critical component of the fuel delivery system, this filter effectively traps solid contaminants such as rust particles, sand, sludge, carbon residue and emulsified water mixed within diesel fuel before fuel flows into precision fuel injectors and high-pressure fuel pumps. Manufactured strictly in accordance with original OE specifications and dimensional standards, it maintains stable fuel flow pressure and ensures complete diesel combustion. It greatly minimizes internal wear, corrosion and clogging of delicate engine fuel components, optimizes engine power output, cuts down excessive fuel consumption and black exhaust emissions. Widely used for long-haul logistics trucks, construction fleet vehicles and commercial heavy trucks, this filter undergoes rigorous factory performance testing to meet international filtration industry standards. We support bulk wholesale orders and custom packaging, paired with reliable after-sales service, making it a trustworthy spare part choice for global auto parts distributors, repair garages and fleet maintenance teams.
