Water in diesel fuel is one of the most damaging and common causes of injection system failure on construction equipment — it causes injector corrosion, accelerates pump wear, and leads to the kind of fuel system damage that costs far more to repair than the separator that would have prevented it. On Caterpillar C4.4, 3054, 3024C, and 3034 engines powering the 420D and 436C backhoe loaders, the fuel water separator is the first line of defense: it removes free water and contaminants before they reach the injection pump and injectors. This direct-fit replacement separator (130-7092) restores that protection, keeping your Cat fuel system clean and your equipment productive on the job site.
Clean fuel, protected injectors, productive equipment. Order today — in stock and ready to ship.
