Hey guys pulled my Injectors today from my rail when I took it off and replacing the o rings the packet I bought from repco for 55$ weren't the right size that he said they would fit even showed a sample looked fine but were a bit fat won't fit in the rail
So guess ill take them back, and get some from an Injection place or somewhere else but what size should I need or just take the sample with me?
Or any way to shrink the outside of the ring?
Thanks guys
Ethan

For such an important part why don't you get the genuine article from a Toyota dealer?
Google http://www.toyodiy.com/parts/  for the correct part no for you model.
 

This is true, but I need it fixed within a day or two it's my daily..
Don't think they would have them off the shelf :(

Can you not use the old ones?

Nah they look a little crappy and ones missing a little but from one

Your O rings are the same as used in Celica's, Corrolas, and Camry's and many other models so I wouldn't be surprised if they were in stock.
