Here is a link to a pic of my 261 as I set it up for a remote full flow filter:

The hole nearest to the filter is for the return line and the hole closest to the firewall is for the incoming line. The "plug" that needs to be driven in is just above the reurn line. I drove mine in about 1/2". I have been using mine for about a year now and everything seems to work well. Let me know if you need any further help.
