Have a leak on passenger side of my truck after the lines come over. The problem is that I cannot get to them very easily. Anyone ever had to replace I think it is the return line leaking because only when running it starts to leak. However, I do not know best way to get to it to replace with rubber gas line. Any ideas appreciated.

Leaking while running is more likely the pressure line. The return line has very low pressure in it as it has no restrictions after the pressure regulator.
Rubber line is not what you want for that system, especially if you use fuel with ethanol in it. You can get replacement likes from places like Rock Auto, you will probably want to check the entire fuel system for damaged lines, there are a couple places that set in pockets where dirt/salt/water collect and they rot out, even when the rest of the line looks like new.
That system runs between 40-50 psi and you really do not want simple clamped rubber lines.
