Gutshots are 10:1 based on card odds on the next cards, but I give it a 7:1 implied odds on a rainbow flop, 3.5 to 1 implied on 2 over cards and gutshot, but then discount it to 14:1 if the flop is two suited. You did you have 18 to 1 on the flop, making it correct to draw technically.. but, you got lucky in my opinion. There were 5 people to act behind you, any of them could have easily value bet raised on a flush draw or any other reason. That would have made your crappy draw even more crappier and trapping you into calling more than you'd like. I personally would never chase a gutshot to the river, no matter what kind of odds I had.. unless there were other out possibilities, such as an improvement to a backdoor flush draw.
