I'm doing a little fuel line work now and was wondering if any one has any tips or pics on replacing the 3 lines (got the line set from dpi, very nice) on the right side of the unit? They look pretty self explanatory but I'm nervous. Another tid bit is when I took the frequency valve line off the valve it was totall clogged but the passage going into the unit was completely clean. I guess my question is what kind of problem should I have with a totally clogged valve?
