Doug:
I am using a Mallory unit that mounts between my fuel log and the gauge. Very happy with it. It is made of billet aluminum, beautifully crafted, and nicely anodized. You can find them at Jegs, and as I recall, they run about $70.00. Auto meter makes one also, but I appreciated the look and workmanship of the Mallory unit.
On my Kirkham, I mounted the line from the gauge thru the firewall, to the isolator, and then a short piece of line from the other end of the isolator going to a 90 degree elbow which screws into the log. The isolator itself lives under and to the center of the puke tank.
Hope this helps.
Bud
