ok guys im in the midst of swaping my tpi v6 out for a carbed 350 (69 elcamino non original)

heres my question i know my car right now has 2 fuel pumps 1 in the gas tank and 1 on the side of the engine

ive heard that i have to remove the one in the tank BUT!!!!!
i was thinking since i want to Shoot a 100 shot on the motor
would it be smarter to put a fuel pressure regulator into it and just keep the pressure down for when im not spraying?
does this make any sence and could this work with a machanical fuel pump on the motor

thanks

 

Leaving the pump in the tank and pulling through it has been done. However, I would reccomend either removing the pump in the tank, or installing a return-style regulator to regulate the pressure.

 

The mallory 3 port seems to be working well for me.
