Just want to double check this:

Out of the petrol tank straight to the fuel pump
From fuel pump to the fuel filter
From the fuel filter to the solid line that runs to the front of the car
From the solid line straight to the fuel rail
From pressure regulator thingy to the four way splitter (there is also another feed into the splitter from the airbox)
From the splitter down to the fuel cooler (those cars with A/C)
From the cooler all the way back to the carbon canister, then into the tank again

Correct?

hmmmm scratchchin As far as I can remember, one line goes into the Fuel cooler. The other line from the cooler then goes into the rear of the Fuel regulator.

This is the setup on my 98 4.2

Out of the petrol tank straight to the fuel pump
From fuel pump to the fuel filter
From the fuel filter to the solid line that runs to the front of the car
From the solid line straight to the fuel rail
From pressure regulator thingy to the fuel cooler
From the cooler back to the other hard line and back into the tank

The 4 way and carbon cannister are part of the emissions control not the fuel supply
The four way splitter has 2 hoses, one into each intake manifold
Another hose into the airbox
And the fourth goes back via the transmission tunnel to the purge valve on the carbon cannister
