I have a cummins 4bt which I hope to install in my 28 sometime in the next month. I am working on the fuel lines, specifically the fuel return. On the side of the 4bt's there is a fuel injector return line, that t's into one line returning to the injector pump and the other ends goes to a straight section of tube with no connector and thats the fuel return. What kind/size fitting do I use to connect to a hose, ideally I'm thinking a 1/4" return hose.

Normally you slide the hose on the tubing opposite the compression fitting with a clamp or two.
If that fitting is to small, 3/16", bell a piece of 1/4 tubing over it and braze or solder.
