From my research, i have decided on using a fuel tank from an 87-90 jeep wrangler ($75) and straps ($15) from rockauto.com. It seems it fits between the frame rails and it is baffled which a blazer tank like i used in the maroon truck in profile pic is not. Blazer tank also has a smaller hole for sending unit not compatible with electric pump senders. Im also going with a 92-94 S10 blazer sending unit ($50) and 96-97 sliverado ep381 fuel pump (already have).
I didnt figure this all out on my own. I came across it here:
