305 to 350 tbi which fuel pump do i use
I just did the 305 to 350 tbi swap and now I need to put a new fuel pump in. The old fuel pump just does not keep up with the new motor. The motor has a little hesitation and it is because of the pump. Which is the best fuel pump for this application? I heard of the Walbro 190 pump, but when looking on ebay all I could find is the Walbro 225. Is that pump just as good or better? Also heard of using the tpi fuel pump. Which is the best, all opinions are welcome.

The Walbro 255 is probably the "best pump", but a stock replacement TPI would be a "good choice".

Would I be able to use the Walbro 255 by itself or do I need a regulator to reduce fuel pressure? This basically a stock 350 tbi motor, but I want to put in a pump with plans of engine mods in the near future.
