What type of car and fuel system do you have?
carb or injection,mechanical or electric pump?
TPI or TBI style injectors?
And for what purpose do you need more fuel pressure?
Is the engine running out of fuel now,causing it to surge under heavy load?
Any other important information will be helpfull

sorry wasnt thinking, its a 600 cfm edelbrock carb (1406) on a chevy 350, pushrod fuel pump. When i go WOT, it feels like its not getting all the fuel it needs.

fuel

There are a few things that can help...

1. Try a fuel regulator in the line (these are fairly inexpensive)
2. Upgrade your fuel pump to either a better cam activated or
eliminate it altogether...
3. Upgrade to an electric fuel pump

Among other things, the fuel regulator really helps - also, try installing a Fuel pressure guage, and see where you are at.

EDLEBROCK recommends only 5.5-6# fuel pressure for their carburetors. If you go higher you risk the good possibility of flooding due to the pressure acting against your needle/seat valve.
Put a fuel pressure regulator and a gauge on it and adjust it to their recommended pressure. The HOLLEY #803 plain finish regulator from SUMMIT RACING is about $23.00. You can get it also in polished for about $35.00 and chrome for about $45.00. It uses 3/8 npt inlet and outlets and comes with a mounting bracket. The liquid filled fuel pressure gauge is about $20.00 and requires a 1/8" to 3/8" reducer to fit one of the outlets. That costs about $4.00. The other outlet goes to the carburetor.
Avoid using the type of fuel pressure regulator that has a dial knob on the top, they're not known for their accuracy.
Here's one of the HOLLEY #803 regulators and the liquid filled qauge on my motor. I chose the polished version.
