The Fuel Filter Joint Bolt with OEM numbers 1-09675037-1 / 1096750371 is a verified direct-fit replacement for ISUZU VC46 trucks and equipment equipped with the 6SD1, 6WG1, 6HK1, 4HK1, 6HH1, and 6BD1 diesel engines. This specialized hollow banjo bolt is a critical fastener in the fuel system, responsible for mounting and sealing fuel lines, fuel filters, and banjo fittings to prevent fuel leakage and air ingress.
How It Works: The joint bolt functions as both a mechanical fastener and a fluid passage. Its hollow internal channel allows diesel fuel to flow through the connection while the external threads secure the banjo fitting to the fuel filter housing or injection pump. Sealing washers on either side of the banjo fitting create a gas-tight seal when the bolt is tightened to factory specification.
