We used the boyd welding carb tank and simply dropped in a LS1 fuel assembly I got off ebay for 50$
It works great and was simple to do. The tank also came with a fuel sender so my fuel gauge will work properly now. My dad made the truck a short bed. I bought new bedsides to help with that and they shorted the frame. Found a deal on TTII rims in 18x8 and will be installing those shortly. The rest of the truck should be finished and assembled next week some time. We used a single stage paint.
