Gmt-900 Fuel Tank Vent?

[aczr2k]

Just had my fuel tank vent replaced today( 8 months old, 18K miles). I had remembered something about a relocation kit on the previous generation trucks? Have they changed since then, or is it something I should question them about when I bring my truck back in tomorrow to get a O2 sensor replaced (out of stock today). I do drive a lot of gravel, dirt roads. The Ses light had been coming on/off for the last couple of months, a few times it was almost impossible to get fuel in it. Just want to make sure I get the latest update, to eliminate another trip. Thanks!

We haven't seen any issues specifically on the GMT900's,But we have been going through them "in general" on all models.
