Fuel Pressure Regulator with Weber Install?

Will i need an adjustable fuel pressure regulator when i install my Weber? And if so can someone direct me to a good one? Thanks alot. L8R.

I cant speak for anyone else but i dont have one on my truck and the weber has been on over 4 years. I use the stock pump and the weber.

put a small inline fuel pressure gauge on the incoming fuel line.If u r getting 3-3.5 psi at the carb,u r fine .if the pressure is 5 psi + u may need a regulator.bj
