Alright, here is situation. Fuel pump in tank is going out. Have 350 TBI in 89. Getting a 454 from Frisbie in July and am going to go to TBI on it, so question is what fuel pump will work on mine now, and still give me enough pressure and flow rate for the 454. What is current pressure for the system? 30PSI? and flow rate? Debating on going to external pump? Has anyone did this? and how did it go? Any input would be nice as I need to get truck running reliably again. Thanks.
