Late 4.5 D-Jetronic Fuel Injector Special Seal Set

Store > D-Jetronic Fuel Injection Products
Used on some 1973 and all 1974 and 1975 V8 fuel-injected engines. You must confirm before ordering by removing one of your injectors.

If you plan to replace, test, or service your electronic fuel injectors you first must determine which bottom seals you will need. If you have a 1970 or 1973 model, you most likely have the single-bottom seal (unless your engine has been changed). If you have a 1974 or 1975 D-jetronic V8 you will need to remove one of your injectors and confirm what you have before ordering. Watch Kent explain this issue in detail in the YouTube video below.

Product Details

This is how the two seals are installed on the end of the injector. When ordering you will receive eight sets of seals for a V8 engine.
