Additional fuel filtration / injector replacement poll

[GordonMarks]

The Suburban:
Changed injectors, presumably because it had been sitting for a while in our DRY weather. Engine has a little less than 100K by what I can tell from dealer info & extrapolating the tag info before it was wrecked.
Stock filter(DELCO only),& I added an old Raccor 500 10 micron (I think)like we used on the 5.7L & 6.2L(BOY, that was FUN!!!) I don't have the room that the later ones have. Nothing in it after 5K. It's before the main filter. I try to buy fuel where I think they will have a high turnover.

See below for filtration installed (installed within 10,000 miles of new in both cases). I just had someone check my injectors with a TECH 2 on the 03 since the 7 year warranty is expiring. The check showed that the injectors (return rate, etc.) are right on the money.
