You're not going to be able to seal a fuel rail gas leak with tape. You are asking for an engine fire by driving this car without changing the fuel rail.

Rock Auto lists a new one for $106.79, AC/Delco part number 12499784.

You probably could stop the leak with hose and clamps, but with 40 lbs of pressure do you really want to risk a fire? The right thing to do is replace the rail it is not really a difficult job. I found a fuel rail with all injectors and fpr for 25.00 on ebay. A junk yard couldn't cost you that much.

Returning home from a 700mi trip we saw a small ford truck towing a trailer stopped on the side of the road the driver appeared to be throwing up. We stopped for gas and resumed our trip, some time later the same truck/trailer was on the side of the road on fire it was very ugly, (flames and black smoke) the smoke even filled the inside of the vehicle. I can only assume the driver was getting sick from fuel leaking from the engine area and was trying to make to a exit. As it was he was at the entrance to a rest area. I strongly advise to replace your fuel rail with a known good one . Mike

Let me clarify. The recall was for the '95 - '97's. They where replaced with a SS rail. GM continued to use a plastic rail on the '98 & '99's albeit a different plastic compound. See if you can find a SS rail in a junk yard. I am pretty sure they went to a steel (not stainless) fuel rail in 2000 and one of those might even work.

Just to reiterate what everyone else said, patching it is a VERY bad idea. A fuel leak is bad enough, but under pressure it becomes atomized and that is MUCH more dangerous than a plain old liquid leak. DO NOT take any short cuts when it comes to a pressurized fuel line.
