First things first, new to the forum, joined just to ask these two questions. 1 is it possible to add on a driver information center to a blazer that doesn't already have one, or do it after marker? Second question my manual says I have 18g fuel tank, yet I have never been able to put more than 13.2 g in already one time. Is this common? I Hated suv's for a long time. now I have my 02 blazer ls, u enjoy making that guy look as beautiful as it looks to me now.
