I'm not sure where it goes, I am only aware of it from reading about it. I'm thinking the closer to the tank the better, as for fuel lines, there is only one, there is no return line, the pump runs constantly while running and the return line is actually in the top of the fuel pump, this keeps a constant flow of fuel going thru the pump and keeps the pump cool. Yes, it uses gas to cool itself.
I've had mine 'stick' in my XJ, usually a couple of bottles, one right after the other, of Chevron fuel system
cleaner, not fuel injector cleaner, frees it up.
I've got that problem now on one of my TJ's, takes about 15 seconds cold start in the morning, just have not picked up any cleaner.
