How much weight gain from adding a Dana and roll cage.

Not hard to do, the submersible fuel line was like $90.00 for 2’!!!! It went through the filler hole. Push the magnets into place with a stick. Should have wrapped the stick with tape. Got a little wood dust in the tank from the stick, which annoyed me. Put the mat in, then put the fittings on. The mat alone folded up is a tight fit through the hole. Then just cut the pickup tube before the 90 deg bend. Holley has a video of it working.
