Description

2001-2004 GM 6.6 Duramax Diesel LB7 Injector & Return Line Seal Kit

Dipaco part number DT660021 is a kit that includes four injector body o-rings, four injector nozzle gaskets, and five injector return line gaskets, which is enough to reseal one side or four injectors on 2001-2004 Chevrolet & GMC trucks with the 6.6L LB7 Duramax diesel engine.

When installing a Duramax injector, new seals and O-rings must be used.  This kit includes new copper washers for the injector tip, new copper seals for the injector return lines, and new O-rings for the 2001 to early 2004 LB7 Duramax engines.  One kit is enough for four injectors.

Two kits are needed for a complete engine.
