I'm going through this myself. I took up the rear seat to dismount a strobe controller.
It might be possible to cut a hole but if you do, it'll have to be through 2 layers of metal.
I don't know. Being that i'm dealing with it on a tar type of driveway, i'm paranoid about jack stands, and I have some heavy duty truck ramps, luckily my jack raised it up enough
to slide the ramps under.

The main reason i wanted to post was that there is a U tube video showing how to take a sharpie top and turn it into an unlocker for the brake line. I'm debating the external fuel pump idea, since I have a couple of them. First thing first though, test power at the pump and give it 12v. I figured I'd run a line from the trailer wiring connector with the parking lights on. Should be already fused, shorter, and easier. I've already verified the IFS is gettign juice and working properly.
