ok so today I went to go and replace my injectors o ring's. The two of them. Bottom and top. Its 660cc RC injectors. So anyways. Go down to checker auto parts and ask them if they have the set. Nope they only have the oring for the top, where the injector meets the fuel rail.

Now when I first took out the injector.....it had two(2) o-rings. kinda WOW'd on how that work but it did! So when I got the one from checkers it was only one and it took up 3/4 or a little more on the injector. So Im wondering what kind of o-ring's do I need? This is for a mitsubishi eclipse 1997 GSX... Heres some pics

I just went to the local autoparts store to get my o-rings on the top of the injectors. they worked perfectly fine. they were cheap too. Much cheaper than getting them anywhere else. The bottom one I could have got at the autoparts store for about 12 dollars for that seal and the other seals for 1 injector. Its really pricey for the bottom seal. I bought mine from JC Whitney for 20 shipped.
