Hi, if it's the same as a 3.5, the line attachs to the tube inside the leg, out to the head and out the other side. Hope this helps, you'll have to forgive my crappy camera!! Dirt

Default Close but not the same

Thanks Dirtman, the engines are close but on the 7.5 there is another nipple under the one that the head goes to. It is positioned 3/4" lower and 3/4" forward. Thanks again, BAD ANDY

That one is your fuel pressure fitting. That goes to your tank at the vent at the top of the tank. It pressurizes the fuel system for better fuel draw.

Go to K&B's website and you can get a full blow up of parts for the K&B 7.5cc outboard engine. I've got one on a tunnel hull and man does it rip the water. K&B's site is modelengines.com. Hope this might help

I can make you a picture of my correct installation. I have a near vintage configuration run once sitting on a dumas 7.5 hotshot.
It is a screamer that needs heavy front end ballast to keep from becoming ballistic. Still need info let me know. I will look for a picture, post it on one of my website pages when you reply. I have many construction photos taken also and may give different views of my installation.
