Heres the work me and Alex did on my car:
I already went through the hassle of dropping the rear and tank twice, but not only did I not feel like going through it again in the rain, but like Alex, I have a welded y-pipe now so it would clearly be more of a problem than before. Also, it's an aftermarket walbro pump, so I'm sure I will have great use of this access panel time and time again.
EDIT: we used electric sheers, after measuring and masking we had it cut out in 5 minutes.
