PURPOSE
The carbon canister is designed to soak the fuel vapours from the fuel tank when the engine is turned off or parked in a hot or cold location.   Over time the fuel may expand and the vapours are soaked up by the carbon canister.  When the engine starts the vacuum will draw the vapours, recycle them, and  prevent the vapours from entering the atmosphere. 

THINGS TO LOOK FOR
The carbon canister may be full of petrol if the fuel tank is full and may start to overflow with petrol.  The carbon canister should be checked at least every 20,000-50,000kms to operate correctly.

IS IT EXPENSIVE TO REPAIR?
The carbon canister is rarely replaced.  If it needs to be replaced, go to your local spare parts outlet or the wreckers.

PURPOSE
The fuel pressure regulator is a component that regulates the pressure in the fuel rail and also removes the excess pressure and recycles the fuel back into the fuel tank.  The fuel pressure regulator alternates the pressure on idle and full throttle.  This is a physical component.

THINGS TO LOOK FOR
A fuel pressure regulator should have a vacuum hose connected to it.  If not, this will affect the performance of the fuel pressure regulator.  Also a power loss or a non start may occur due to a faulty fuel pressure regulator.

IS IT EXPENSIVE TO REPAIR?
A fuel pressure regular costs around $80.00-$90.00 and is best fitted by your local mechanic.
TEMPORARY REPAIR AND LONG TERM REPLACEMENT
A fuel pressure regulator can be replaced but it has to be proved that the regulator is faulty and this can be difficult.
