Hi, I'm new to this group, but not to Ferrari. I have owned my '85 GTB QV since new. I have a simple question. I have a bad injector that I want to replace (yes it's definitely the injector). I have the new injector, and a new seal, but for the life of me I can't figure how the old part comes out. I have removed the snap ring. Below that there seems to be a retainer of some type over the seal. I would have expected the injector/seal/retainer to just pull out after removing the snap ring. But it doesn't seem to want to budge. I probably just need to pull harder but before I do something regrettable I though I'd ask. Any help would be appreciated.
