I originally had 3d printed some brackets for holding the hoses in place. I wasn't happy with the nylon print material and stepped it up to metal. I ended up using 3/4" by 3/4" 6160 1/16" aluminum and picked up the original 2 holes from the floor angle. I then put a couple #12 holes in for Adel clamps.
I then riveted the fabricated angles to the floor with 2 LP4-3 rivets and bolted two adel clamps to hold the fuel and brake lines in place.
