Corvette filter/regulator
Where does Chevrolet install the filter/regulator in the cars? I have seen the video done by S&P and they put it back by the gas tank on the conversion they show. Would it not be better if it was located as close to the fuel rail as possible?

Most people put it on the frame rail (or subframe rail) close to the tank. This keeps the lines to and from the FPR short, and you only have one long line, which for most applications can be the stock line, or a new line following the stock run.

If you review S&P's video, Mark suggests that the failing of a single line system is that it allows the fuel at the engine to heat up and cause vapour lock which is why they modify the LS1 vette fuel systems to switch to a return line. I am inclined to agree with him on principles but if vapour lock was in fact a risk, I can't understand that Chevrolet would risk it in the corvette.

The only issues we ever have is on a completly empty rail. Sometimes the air gets trapped in the back of the fuel rail, but it eventually gets out.

On the other hand, the boiling point at 14.7psia (ie, in the tank) can be as low as 100F for winter blends. If you are heating the entire tank up by constantly pumping all the fuel through the hot rails and back to the tank, you can boil the fuel in the tank pretty easily.
Some vendors make really nice shiny parts that amuse people who like shiny things. A lot of them are really nice people, and they are a great source for shiny parts for show cars and advice on appearance improvement. They aren't a great source of technical advice or performance parts.

They had to eliminate the return lines because of emissions standards. The fuel coming back from the engine hot and dumping into the tank leads to higher levels of evaporative emissions, so they shortened the return line to keep the fuel that returns to the tank cooler.

I put mine here
but I do not like how the stock lines are very close to being pinched. any recommendations about putting it where my stock filter is?
If I get the russel GM/to AN adapter how can I connect that to the existing line? I have a 45 flaring tool but I think AN uses a 33 flare?? Are there any other OE type parts I could look at??
TIA
