Based on community knowledge gathered in a previous post it turns out the PO of my 73 2.0 had the supply and return lines reversed underneath. I now have ALL NEW hoses AND the correct fuel filter AND a reducer pipe from Tangerine, but want to make sure I am right before I start cutting the lines.
Going off this diagram:

If I use the measurements there I will have too much in some spots and too little in others. I am guessing these numbers are not based of having SS lines? Does it matter is I have more/less in runs between connections?

And, I believe the SS lines above the shelf are correct. Supply in front and return in the rear. On the underside you can see where that positions them which is tight.Attached Image

No problem sir if the fuel line length is more, don’t overthink it sir.
This one I did on one our members.

And if your original pump is not working, just use the 75/76 fuel pump. One In and One out. Much easier and simple.

Awesome, thanks! Had actually found the thread with those photos which look exactly like the ticket.

If you are already this far in, take the little extra time and move the pump up front.

Seriously, every time I have not relocated the pump I have wound up regretting it.

Just a little extra time? Okay.

In the 17 years that I've owned my "73 1.7, I've never had a problem with the FP in the back.

Except for having to replace the FP because it leaked.

P.S. It's time for a new spell checker.

I'm also a fan of having the fuel pump up front, and easy access. Best, MarkAttached Image

Wasn’t planning on going this far until finding the reversed routing of the PO. Read of the dreaded vapor problem. The Porsche tech doc solution has been done. But brother is it tight in there. Not to mention every single clamp was oriented as if you sat in the engine and assembled.

Neat install, but it appears you retain the original plastic fuel lines thru the tunnel, not safe practice. Go SS replacement for potential fire reduction (IMG:style_emoticons/default/WTF.gif)
