Not sure on your deck layout. But I just replaced mine in a 1989 23 Gulfstream. It was a challenge but can be done. I had to cut an access hole in the gunnel near the fuel fill point. Then I removed the deck, disconnected the lines. I connected the new line with two zip ties and electrical tape to the old line to make a smooth transition. Then I pulled my brains out from the fill point. It worked and they are in. Good luck and be patient.
