is acting up. 2005 Impala. I need to change fuel pump. Other years, and even some cars same year has access panel to get to fuel pump. Mine however don't have it. So, question is, has anyone here dropped the fuel tank to change fuel pump for very similar car? Tried YouTube, no luck there as it don't have it. Another thought was to just cut a hole where pump is located, but if I grind it, I'm right over tank...... Open to suggestions.
