Hello and thanks in advance for the help. I took apart my dad"s 2001 Ultra Classic which hadn't been ridden in a while due to health problems. I was going to change the fuel filter and clean out the tank. Well the quick disconnect o-rings started to leak on both the hoses and the tank fittings. While getting the rebuild kits for the fittings and hoses, and yet more health problems, the bike sat awhile again and now I'm having problems putting her back together. I don't know which tank fitting is the high vs. low pressure and which of the hoses going to the throttle body is the high vs. low. I know I should have labeled it and took a quick picture but this was supposed to be a half hour job not a year! Also, where the heck does the in-tank return line mount to? I can't figure it out and don't believe it just flops around in the tank. Thanks again!

 

It should be pretty obvious. One is longer than the other. Longer in front shorter rear.
