Can anyone give me a part number for an injector sleeve remover and installer for a C7? The CAT book shows a conglomerate of pieces, but a quick Google search reveals many other tools. Curious as to what anyone else is using. Got one that is getting coolant into the fuel and I suspect injector sleeves are leaking. Even if they're not on this one, we have plenty of CATs to keep us busy, so I'm sure we'll be needing the tool eventually. Thanks.
