magneti marelli EFI 2001 Road King

I have a 2001 Road King with the Magneti Marelli injection system.

I recently removed all of the sheet metal to have them painted, including the tank. I got the paint back and put the bike back together over the weekend. I tried to start it, and nothing. I believe I either pinched a line inside of the tank, or swapped the fuel lines backwards so that the pump is trying to pull from the return, which of course, there's no fuel.

I went to the HD dealer over the weekend, and the shop manual is poor at best. Can someone definitively tell me which line from the top of the manifold between the cylinders is the high pressure (to the pump) and which is the return? I want to start with potentially something I did. The bike ran before I started this a couple of weeks ago.

Thanks for the help!

If you think you swapped the lines around just swapped them back around. Then you'll know if that's it or it's something else. Of course you could also use a fuel pressure gauge to make sure you're getting the correct pressure.

Turns out I had it plumbed and wired correctly but pinched toe filter sock at the end of the pickup. I straightened this out and it now runs fine.

Thanks for the quick response!
