I do believe my fuel in my 1991 has gone out. I still have some things to check to make sure, but that is where the facts are pointing. Here is my question. I plan down the road to do a 5.3 swap. With that being said. Could I swap in a vortec pump or a walbro 255 and it run ok with the stock TBI 350? I know it's a bypass style regulator so in theory it should work. But is that too much pressure for the regulator. The truck is my daily driver so right now reliability is more important than preparing for future swaps.
