injector question

So I was putting the UIM back on my s5 tii. (after deleting emissions)When I got to the secondary injectors they didnt fit sung in the LIM. i went and looked at some s4 n/a injectors saw these rubber rings popped them off and they are to big for the s5 injectors. My question is are all usdm injectors the same size as in the same size mm? Anyone know where to get what I need? I thought about buying a denso seal kit.

All the injectors are the same external dimensions. Are the air bleeds still in the manifold? Without them the injector won't have anythin to seat into.

napa sells injector o-ring kits for our injectors. i think they are like 3 bux per injector? if your air bleeds are broken or missing as aaron stated, cj-motorsports sells replacement "seats". you remove the air bleeds and place these in the manifold

Are you positive your current injectors are stock?

the part number for the bottom grommet is different S4 vs S5, so its very possible the S4 ones wont work in an S5....
