I haven't been very regular since reading about the Duramax injector problems. What's up? Do you think it is a filter issue, fuel issue or a quality issue? I wish I could convice myself that an after market fuel filter will cure all problems but no filter in the world can make up for manufacturing quality problems. Isn't it feasable you could install better filtration and still have injector problems? I just like feel I'm sitting on a time bomb! We have quite an investment in the D-Max and I for one don't feel happy about the probable chance of a repair bill higher than the initial cost of the D-Max to begin with. Can anyone help me feel better????
