Yeah right! I have a scar on my left forearm from when I did mine last summer...a gentle reminder that I never want to do it again.
It would because it's just been done: https://gmtnation.com/forums/threads/trailblazer-fuel-pump-r-r-without-dropping-the-tank.20325/#post-588310
I prepared myself for any cuts! I bought one of those brown elastic wraps, and wrapped my right forearm with it to avoid cutting myself. It actually worked too! Ended up cutting the wrap but my arm mostly survived, aside from it aching from going through that tight crummy angle.
