When those seals harden or a cup erodes, combustion gases chuff past the injector, fuel washes down into the oil, or a cylinder runs rough. A complete seal, cup and tube service kit restores a gas-tight injector seal and clean fuel control whenever the injectors are pulled or a leak is traced to the injector base — the correct way to reseal rather than reuse tired parts.\u003c\/p\u003e\u003ch4\u003eWhat's Included\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003einjector combustion (copper) seals and O-rings\u003c\/li\u003e\n\u003cli\u003einjector cups\/sleeves and connector or ball tubes as applicable\u003c\/li\u003e\n\u003cli\u003ehold-down and related hardware where specified\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eFitment\u003c\/h4\u003e\u003cp\u003eFits Chevrolet, GMC trucks equipped with the LB7 Duramax diesel engine, 2004.5-2010.
