Having previously drilled the necessary holes and fitted the catch tank bracket, the remaining task was to fit the oil hose from the top of the oil tank into the bottle. This requires an appropriate sized hole to be created in the top of the last tank.
The front left hand side of the catch tank (which from other peoples blogs seems to be the desired entry point for the pipe) was masked and the pipe was drawn around to mark the required hole. I don't posses a step drill and so choose to drill multiple 4mm holes within the drawn circumference. A Stanley knife was used to cut through the remaining material, and a Dremel smoothed out the hole to the required size. I assumed that a reasonable friction fit was required between the pipe and bottle.
Once the tank was fitted on it's bracket with the pipe located in the tank, the required length was measured and cut to size to fit onto the oil tank. Given that the purpose of the catch tank is to provide a safe reservoir for oil particulates and vapour emitted from the top of the engine block, I assumed it would not be effective if the oil pipe was fitted flush on the bottom of the tank - a diagonal cut was therefore made on the end of the pipe to avoid a seal being made between the bottom of the tank and the pipe.
The catch tank comes fitted with a rubber cap and a hose which was routed downwards through the chassis with the end facing the ground.
