Me and my friend are working on getting a '79 Alfetta back on the road after 11 years. We are now onto the fuel system and our question is what should we do to clean out all the old stale fuel from the injectors? I found 3 spare ones in the garage and are going to do those first so if we screw up on one, we don't cause a complete halt in the project. And if the spray pattern is bad, what do we do to get a correct spray? Any help is greatly appreciated.
