which tank for ls build

[49ads10]

I hate posting as I know this info is all over the place, so sorry in advance for the stupid question. I am trying to figure out the best option for the fuel system. I have swapped my 49 over onto an 86 S-10 frame. The s-10 had a2.8l TBI so I've got to change tanks and pumps to do it right. I've seen many different routes. Tankinc with a mid 60's mustang tank setup for FI, run their pump with the walbro pumps, etc. Total setup though would run 500+. Was also thinking about grabbing a newer blazer tank with the 4.3L engine so it would be setup FI. They grabbing a new walbro and just swapping pumps. Would that work? That would run about $350.

Either way I still have to deal with regulator, lines, fittings, etc so those costs are separate.

What are you guys with S-10 LS setups running?
