What is the optimum pressure for this carb. What is the optimum flow rate. Changing to electrical fuel pump and regulator on 87 YJ jeep
Here's what you need to know about the optimal pressure and flow rate for the Crown Automotive 83320007 Carter BBD carburetor on your 1987 YJ Jeep with a 4.2L engine:
Optimum Fuel Pressure:
The general consensus for a Carter BBD carburetor is to run with a fuel pressure between 4 and 5 PSI (pounds per square inch).
The Carter BBD can handle slightly higher pressures, but exceeding 5 PSI can overcome the carburetor's needle and seat, leading to flooding and a rich running condition.
Since you're switching to an electric fuel pump and regulator, it's crucial to get a reliable regulator that can consistently maintain this pressure range.
Optimum Fuel Flow Rate:
The fuel flow rate requirement for a stock 4.2L engine with a Carter BBD is not as critical as the pressure, as the carburetor only draws the fuel it needs to maintain the fuel level in the float bowl.
A typical electric fuel pump for carbureted applications will have a flow rate significantly higher than what the engine consumes at any given time.
As long as your electric fuel pump provides at least 20-30 gallons per hour (GPH), it should be more than sufficient to keep the carburetor supplied under all driving conditions. The fuel pressure regulator will then manage the pressure delivered to the carburetor.
The key is to have enough flow to ensure the pump isn't working too hard and can maintain the necessary pressure.

is there a part number for the part that goes on top of the carb opening to hold down the airbox?
If you are referring to the Air Cleaner Bail (J3231263) which clips to the carburetor and has a threaded stud that receives the air cleaner, that is unfortunately no longer available through our vendor network.

Is this Carburetor California compliant?
Per Crown Automotive this is California legal when used as an OE replacement.
