I have fuel pouring out my air bleed valve of my left carb barrel and my inner vent solenoid valve on my right carb barrel. At one time my car was flooding out I found one of my vacuum lines was blocked, now its flooding out again from another area, PLEASE HELP!

we dont have this engine here, USA.
but i have the WG jeep book,
starting page 12 , chapter 14


FUEL INJECTION PUMP BLEEDING
(1) If the fuel injection pump has been replaced,
air should be bled at the overflow valve before
attempting to start engine.
(a) Loosen the overflow valve (Fig. 18) at the
rear of the injection pump.
(b) Place a towel below the valve.
WARNING: WHEN CRANKING THE ENGINE TO
BLEED AIR FROM THE INJECTION PUMP, THE
ENGINE MAY START. PLACE THE TRANSMISSION
IN NEUTRAL OR PARK AND SET PARKING BRAKE
BEFORE ENGAGING THE STARTER MOTOR.
CAUTION: Do not engage the starter motor for
more than 30 seconds at a time. Allow 2 minutes
between cranking intervals.
(2) Crank the engine for 30 seconds at a time to
allow air trapped in the injection pump to vent out
the fuel injector drain tubes. Continue this procedure
until the engine starts. Observe the previous WARNING
and CAUTION.
(3) Tighten overflow valve.
HIGH-PRESSURE FUEL LINE BLEEDING
WARNING: THE INJECTION PUMP SUPPLIES HIGH-
-PRESSURE FUEL OF APPROXIMATELY 45,000 KPA
(6,526 PSI) TO EACH INDIVIDUAL INJECTOR
THROUGH THE HIGH-PRESSURE LINES. FUEL
UNDER THIS AMOUNT OF PRESSURE CAN PENETRATE
THE SKIN AND CAUSE PERSONAL INJURY.
WEAR SAFETY GOGGLES AND ADEQUATE PROTECTIVE
CLOTHING AND AVOID CONTACT WITH
FUEL SPRAY WHEN BLEEDING HIGH-PRESSURE
FUEL LINES.
WARNING: DO NOT BLEED AIR FROM THE FUEL
SYSTEM OF A HOT ENGINE. DO NOT ALLOW FUEL
TO SPRAY ONTO THE EXHAUST MANIFOLD WHEN
BLEEDING AIR FROM THE FUEL SYSTEM.
Bleed air from one injector at time.
(1) Loosen the high-pressure fuel line fitting at
the injector (Fig. 19).
(2) Crank the engine until all air has been bled
from the line. Do not operate the starter motor
for longer than 30 seconds. Wait 2 minutes
between cranking intervals.
(3) Start the engine and bleed one injector at a
time until the engine runs smoothly.

I am in the UK, so do not know this model, but I am a Bosch service tech and can tell you, if you have air in the ABS unit itself, you well need to connect to diagnostic tool with bleeding/venting program on it. The ABS pump needs to run and operate the solenoids to get the air out...

need be more specific are you talking about kodiac 400 diesel engine if you referring to bleed valve the fuel filter housing has the air bleed valve connect a hose to the air bleed valve other in a container remove the fuel solenoid fuse, crank engine short intervals for 10 - 15 seconds until clear fuel with no air bubbles,when you see no air bubbles,remove the hose close the the air bleed valve install the fuel solenoid fuse, then start engine,let idle few minutes see how goes make sure idle good.

Code po449 is for bad  solenoid vent valve.After replacing the valve  check for the   12 volts at the "pink" wire.
This error relates too 

The PCM has determined that a malfunction exists in the electrical circuit for the vent valve/solenoid in the evaporative emission control system.

Definition:
EVAP (Evaporative Emission System) purge/vent solenoid circuit condition

Explanation:
The solenoids and system wiring are monitored for opens or shorts

Probable Causes
1- Purge or vent solenoids defective.
2- Check connector and wiring.
3- Fuel saturated vapor canister.
4- Failed EVAP vent solenoid.

 --------

The cost of the vent solenoid valve is near to 30 bucks. And the valve is located near the gas tank.

Thanks. you can rate this solution and show your appreciation.

you need two persons
open the bleeder screw on the wheel that is furthest from the master cylinder and do the nearest last.
have a person pump on the brake pedal and hold firm while you open the screw, then close it before tell the person pump again
repeat until you see no more air come out
make sure you fill up the master cylinder, do not let it run out of fluid

The electric tank switching valve under the is failing. Though sometimes it's the rocker switch on the dash, MOST of the time the valve itself is going bad. It should be mounted to the frame on the right side of the truck near the cab/box crossmember.

The check valve is a small brass fitting where the return line attaches to the filter head. I believe it takes a 7/16" wrench. There is a 'duck bill' inside that prevents fuel from leaking back to the tank causing air in the system. It should allow flow in only on direction. Some times you can see light through it if it's bad enough. Also, the lines between the injectors can dry out and start to leak air. Air will leak in before fuel leaks out, and you won't see it. There are plastic, cup-shaped connectors for these hoses that press onto the top of each injector. They are sealed by two o-rings on each injector body where it meets the connector. These o-rings can dry out and also leak air and fuel. Your Ford dealer or diesel service professional should have the proper o-rings. Any other o-rings might not seal, as they won't be the exact size. You already changed the fuel solenoid when you replaced the pump. It is inside. There has to be battery cranking voltage to it while cranking, and battery voltage with key in 'on' position. The wire attaches to the top of the pump. This is not likely to be the problem, since it restarts every 2 hours.
