| This kit provides 6 small injector o-rings and 6 large injector o-rings. This price is available to you ONLY when you buy 6 injectors from us, either used, rebuilt, or new. If you're buying just the o-ring kit by itself, the regular price is 13.80. The lower or smaller o-ring seals the injector to the manifold. The upper or larger o-ring is not a seal of any kind. It merely allows a way to mount the injector firmly to the mounting piece or pieces. Contrary to what some people may tell you, if your injectors are leaking fuel externally, the upper o-ring WILL NOT stop your fuel leak. If they are leaking externally, then either the hose has sprung a leak, or the internal injector seal has failed. In that case you need to replace your injectors entirely. We sell quality rebuilt injectors and they are every bit as good as a brand new injector. See the listing for pricing and a description. Last update 05/08 |
