that's way different to what you need. The numbers on the side should be 0 280 155 703 (the right one for your year) or 0 280 155 784 (for 99-01)

Plus, the 703's are skinnier. They don't have that beer gut deal going on in the center like stock XJ injectors.

Those look like they fit..... the taper is right. They look very similar to Ford h.o. injectors.

there's more than just physically fitting - they have to have the right pressure and flow. You can always try - what's the worst that can happen - right??

There's a chart floating around with conversions. Op if you do try those be very careful not to knock off a pintle cap in the intake. Its easy to do. Also be sure the measurements are right. There are lots of ev1 injectors that fit.703s are def. Most popular. How do you think someone found out those work? Just be cautious and look for leaks. I would feel comfortable trying it. Although I drove my mustang 10 miles with a broken float and gas all over the engine. A little gas on a cold engine isn't going to start a fire. Obviously if it leaks don't do what I did, don't drive around like that..... I was young and dumb and had to get home.
