Here's just my two cents from a gas problem I had on a 94 4x4. took it mudding, broke the filler hose and got water all in my tank. Because these tanks are metal, it tarnished the inside. I tried just draining it and filling it with high octane but that tarnish kept reacting with whatever gas I'd put in there. Getting a new gas tank fixed my problem.
Before you go dropping $$ on new stuff, I'd try cleaning the injectors with straight seafoam. There's youtube videos of guys building rigs for like $8 to clean them without pulling them out.
