Default Fuel Pump upgrade

Do we need to uprade the fuel pump on these cars when we start modding them? I was looking at the WALBRO 255 LPH FUEL PUMP KIT on brenspeed. Thanks

I'm about to put in a new intake manifold on the car. Which I figure more air needs more fuel. I do have full exhaust, 70mm tb, 73mm mass air. I don't want to get into trouble later on.

Your mods don't warrant a more powerful fuel pump
It will simply pump more fuel past the regulator, and back into the tank
In fact, it will actually pump so much extra you won't need, there is a strong possibility you will heat up the fuel in your tank
This is not good really, the colder that stuff is the better
