Are you sure you have to redo engine mounts? I just used off the shelf mounts with my swap. I'm using two passenger side mounts I believe (the ones with the offset stud). I'm not sure if the frame is different on an HJ though.
Will the 3FE bolt to the existing transmission in your HJ? If so that's another plus.
I used the stock fuel lines with no issues. I would recommend an FJ62 gas tank with the in-tank pump because it scavenges fuel better when fuel level gets slow. However, I used the inline pump (from summit) for a long time and it worked fine.
If you use a stock 2F flywheel you get the added benefit of all that inertia when crawling (less engine stalls).
