I've got a patch at the back of my passenger sill, where it joins to the heel board. can anyone tell me the best way to get about getting it welded? Obviously a patch, but I want it to be strong and to last! Also, there is a fuel line right next to it, so can I just disconnect it at the tank end and swivel it out the way?
Here's the rust hole, cut out.

Option 1: Weld a plate to the existing floor pan, then weld it to the remaining lip, but inside, similar to what it would have had standard.

Option 2: Weld a plate over the hole, having about a 10mm overlap around the hole.

Option 3: Weld a plate over the hole, having a 10mm overlap at the front end, then bend the back of the plate up at a right angle, going up the heel board.
