hello im new the forum ...... I am bagging my 98 chevy Tahoe 4 door ... was bagged but wasn't low enough so thought I would tear it up all again and start allover .. it never really ends lol...I had a question I took out my gas tank since they have it between frame rails and I didn't want it to rub so thought I go to the junk yard and pick one up from a 2 door blazer around 97 goes in rear . so I was wondering does anyone have an idea on how I should put the evap system ... my old gas tank had an evap pressure sensor and the blazer one doesn't .... has anyone even used a blaxzer gas tank on and obs chevy Silverado or Tahoe ....thanks guys !!!
