Where is my supply line on engine?

Easiest way to do this is to remove fuel filter,place gas contaner at line,may need extra hose to hook to line,then turn the key on and let fuel pump drain it for you,

Lol. Thank you. But now my stupid ? My first time working on my truck myself. Do you have access to diagram? Showing me fuel.

For some reason or the other it want let me load diagram at this time,Marylou go to google and type in fuel filter location for your montero,then hit photo,it will give you a good idea where to start.
