I have those same ones, and bought them for the same reason with likley the same setup. In my build thread there's pics of when I installed them into my BBK ORH. Just make sure to make an outline of sorts on some card board as a template before you go cutting on the H Pipe. You should just be able to search "squirts" and find my thread.
Found it! Great help.
May have found a charcoal canister locally , where on the car is the semi hard line that goes to the tank? Maybe a pic?
