my fuel feed line just sprung a leak on my TGP. this is the section that connects to the fuel rail on one side and the other side connects to the fuel line going to the tank. both sides are threaded.
I "think" this is the feed line. its one of the two going into the fuel rail, this is the one towards the front side of the car

I also ask the same question with pictures posted on w-body.com at:

I'd just take it to a local hydrolic specialty place. They can work some magic. They even have the heat insulation sleeves.

I believe a whole new line can be ordered from rockauto, I'm unsure the price, but I don't think it was too bad.

just a follow up. I ended up using fuel lines from a 89 grand prix but they make me a little nervous as they a rubber and not bent metal and the they are very close to the turbo if you do not zip tie they away from the turbo.

other thoughts, at the time i could not get the part from a local store nor the dealership, i also tried going to local specialty shops and they could not make the lines due to the special thread sizes..... i had to go used just yard....
