2000/2001 Magneti Marelli EFI problem
All,
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 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!

well.. for starters, the pump is a submersed design, it sits in the fuel it pumps, has a waffle filter on the bottom of it yes??
the hose attached to the pump is to FEED the system, it doesnt pull from that hose..
iirc.. the front QD is the feed line.. and the back QD is the return..
that tank has a inline can filter in it doesnt it?
the pump would FEED the filter then to the flex line, then go to the quick connect exiting the tank, if that section is correct? you might have swapped the quick connect fittings and are trying to back feed the fuel, which will not pass due to the check valve in the return line, try to reverse the hoses outside the tank to see if thats the problem, they are the same QD fittings arent they? connect the shorter return line to the front fitting and the longer HP feed line to the rear,
if you ooops it, you are trying to push fuel out of the rear return QD, so just connect the front HP line to that QD and the same swap with the return line
