It is located at the fuel pump, control panel, and burner assemblies depending on the model, and serves to transmit drive between mating shafts or pump components in the fuel system.\u003c\/p\u003e\n\n\u003cp\u003eWacker Neuson direct-fired heaters such as the HD50 and HD70 use a single-stage burner drawing diesel fuel through a dedicated pump system. Indirect-fired models such as the HI400HDD use a two-stage burner with a closed combustion chamber, where consistent fuel pump operation is required to maintain proper burner function. A worn or damaged coupling at the fuel pump can result in inconsistent fuel delivery, burner startup failures, or loss of heat output. Replacing this coupling with a genuine OEM part restores proper mechanical connection within the pump assembly.\u003c\/p\u003e\n\n\u003cp\u003eCompatible with the following Wacker Neuson air heater models:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHD50, HD70\u003c\/li\u003e\n\u003cli\u003eHDR45, HDR115, HDR155\u003c\/li\u003e\n\u003cli\u003eHI90, HI90HD\u003c\/li\u003e\n\u003cli\u003eHI110D, HI110HDD\u003c\/li\u003e\n\u003cli\u003eHI120, HI120HD\u003c\/li\u003e\n\u003cli\u003eHI200D, HI200HDD\u003c\/li\u003e\n\u003cli\u003eHI300D, HI300HDD\u003c\/li\u003e\n\u003cli\u003eHI400HDD\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eGenuine Wacker Neuson OEM part, sold by an authorized dealer.\u003c\/p\u003e","brand":"Wacker Neuson","offers":[{"title":"Default Title","offer_id":43401202401328,"sku":"WACKER-5200011788","price":18.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/5200011788.jpg?v=1784138133","url":"https:\/\/cce-industries.com\/products\/wacker-neuson-fuel-pump-coupling-5200011788-for-air-heaters","provider":"CCE Industries","version":"1.0","type":"link"}
