JYK-45 Diesel Generator Fuel Tank Filler Neck Cap Spare

Product Introduction: The JYK-45, JYK-45S, and JYK-2 fuel tank oil filler neck cap is a generator spare part designed for diesel generator set fuel tank access, canopy assemblies, generator control boxes, and related power generation equipment. It is used in the fuel filling area to support routine refueling, tank protection, and maintenance access for standby power systems, industrial gensets, rental power units, and aftermarket service projects. The visible flanged housing and cap structure indicate a practical filler neck assembly for installation on generator enclosures or fuel tank panels, with material options including stainless steel or carbon steel and finish options such as black powder coating or bright polishing. For procurement teams, this part is suitable for replacement stocking, genset refurbishment, maintenance contractors, generator canopy manufacturers, and spare parts distributors. Compatibility should be confirmed by checking the required JYK model reference, mounting form, filler neck shape, cap style, and installation space before purchase. As a professional generator parts supplier, we support B2B buyers with stable sourcing, quality-focused selection, OEM/ODM cooperation, and practical replacement solutions for diesel genset maintenance and power backup equipment supply chains.
