Kenneth,
See Section 15 of the Engine assembly instructions in the manual, page 21 in mine.
Left side oil line length 13.4''
Right side line 14.6''
Looks like you may have two left side oil lines but I am not sure how critical the stated lengths are. Trial fit the right side line, as long as the 'loop back' is not too tight and liable to kink, it should be fine. Right side oil line goes to the rear (inner) connection on the pump but this is not critical, either outlet connection can be used.
