Midfielder Dean Flood rescued Fingal in Lawless Memorial Park with his late point securing a draw against 14-man Louth.
Louth took the early initiative with full-forward Gerard Smyth's 15th-minute goal inspiring a mini scoring spree that led to a five-point cushion by the 24th minute.
Points from Flood, Brian McCarthy and JM Sheridan gave Fingal some momentum but they still trailed 1-7 to 0-6 at the interval.
Louth soon increased their lead to seven points but Fingal were not so lightly dismissed.
With Sheridan to the fore, they hit seven scores in a row to leave the sides level with just six minutes to go.
Louth lost Derek Horan to a red card but went ahead again with a Shane Fennell free, before Flood's late intervention.
