Hey Guys I never thought I would say it, but it's time. Having driven my TBI equipped 91 K5 for a couple of years now the 4V on my 84 K2500 has to go. Don't get me wrong, the 84 runs decent enough, it's just the 91 TBI runs that much better. Some info on the 84 I want to convert. 1984 K2500 350 4V 700R4 no AC, pretty much bare bones stock. I recently removed the pass side tank (leaking) however the selector system was working up till the time I pulled it. I'm leaning towards the FITech system vs a stock system from Howell or the likes. Though I do have some concerns like.... My 700R4, will I have problems connecting it to the FITech system? I believe I also have a vacuum/electrical switch (load?) that assists on the trans. Hopefully the FITech throttle body will accommodate it. Fuel deliverly is another concern. I'm guessing it would be "easy enough" to install a baffled 87 tank and upgrade the pump to a high pressure in tank. However where do I go from there? I can't possibly retain the stock transfer valve. Just wondering what other guys have done. If I'm "stuck" running just 1 tank what will I need to use for fuel lines? Not crazy about the modern plastic type. Steel feed/return lines seem more my speed however how do you attach them to the sender or TBI for that matter? Thanks for all your help!
