Alright, fuel pump is going bad, short inside tank and is loud as hell. Question is, where to buy new one, should I go in the tank, or mount external one? I have a 350 TBI right now, but going to go to a 454 and Turbo City TBI, can I buy one pump now and use it on 350 and still have it work on 454 TBI system. If so, will I need a regulator for pump pressure. Obviously, I would like to only buy one good quality pump and make it work for both applications. Thanks in advance for any info or knowledge on this.
