need pic of oil lines through fuel tank compartment, trying to figure out where holes need to go Options

I am in need to see where people are placing holes in the fuel tank compartment for oil lines when installing a front oil cooler. Here is my fuel tank compartment. Some people are running the oil lines in the channel. My question is if this is the location how do you drill a hole from inside the channel to the main cabin?

Thanks,

I found a picture of a 914-6 gt build. It is from inside the cabin by the foot pedal assembly. The picture is of a oil line coming through the firewall. It looks like it corresponds to the channel in the above pic that I posted. Is there an actual hole through the fire wall already in the 914? Since I can not see very well on my car in the foot well position I can only guess that there is one already and you don't have to cut out any metal in the fire wall. Can anybody verify? If you have to cut out metal to make access through the fire wall how do you do it? Seems like an impossible task if there isn't a hole already.

Thanks,
Buck
