Fuel leak assistance - 1996 Seville

I have a 1996 Cadillac Seville. I started smelling gas, so I checked under the hood. There's a pin hole in the nylon gas line about an inch or two below the clips where it connects to the metal line that goes to the fuel injectors, it's the upper line. The nylon fuel line looks like it's heat skrinked over the metal line where they connect. Is there a way to cut the pin hole section and connect a new section of line without taking the whole line out? I'm assuming the line goes back to the fuel pump and I'd really like to avoid dropping the tank if there's a way around it. I've used gator connectors in the middle of a fuel line and they work great, but I'm not sure I have enough room for one. I'd like to cut out the line below the heat shrink right at the pin hole and put some sort of connector in there to connect the line back, but not sure what would work best. Any suggestions would be appreciated. Thanks!

Thanks! It's the nylon fuel line that attaches to the stainless fuel rail that feeds the fuel injectors. I'm not sure if it's the send or return, but it's the upper one. The Caddy dealers no longer sell the nylon fuel line assembly. I found this out when the fuel line at the other end where it attaches to the fuel pump was leaking. I was able to buy a GM connector that connected/snapped on to the fuel pump fitting with about two feet of nylon attached to it at the auto parts store. I attached that to the fuel pump fitting and cut the old one off about 2 feet in and reattached the new piece with a quick connect fitting at the cut . You just slide each end of the fuel line in each end of the quick connect and they lock in place. It's been on for a couple of years with no issues. It was either that, or buy rubber line and run it over to the fuel filter. I was hoping to be able to do something similar up front. I thought about cutting the nylon line and slipping a piece of heat shrink up over the pin hole leak and then reattach the line with a quick connect, but I'm not sure if the gas from the pin hole will eat through the heat shrink. Thoughts? Thanks again!

Thanks, I fixed it. My car had the stainless steel fuel rails when I bought it 18 yrs ago. I cut the nylon gas line that attaches to the stainless rails where the pin hole leak was and connected the two half's back together by sliding them into a rubber gas line until they were butted back up inside it and clamped the ends. Thanks for the info!
