Fuel piping question

I got to do a little work on running the fuel lines this weekend. My lines are now run up to the cross frame area for the trans cross member. I ended up having to loop the return line just before it goes back into tank so I didnt interfere with the shock on that side. I don't think it will effect anything. My next step will be to do the lines going thru the cross frame and up to the regulator which I will mount on the passenger inner fender. Where I have drilled to run the lines thru the frame I purchased double walled shrink tubing that I am going to insulate the line as it thru the frame. Then from the engine side of that frame I will be using a heat resistant covering to keep any heat from the headers off these fuel runs. You will see both insulating methods in the below pics.
Here are the pics so far:
