Re: what is it..where can i get it....
Couple of other tips:
1. People are willing to help you, but you need to help them too. Be more specific, ask and answer questions in the same thread as much as possible, and let people know what you have done. That way ppl will come back and try to continue helping you until you get your problem solved.
2. Post questions in the correct forum. You have a Suzuki motor. There is a Suzuki forum. Post your threads there, that is where ppl with the most knowledge of those motors hang out. If you keep posting in the wrong place, not only will you not get much help, but you may find your threads deleted instead of moved.
3. Keep in mind ppl are somewhat helping for self satisfaction. You should thank them if their advice helps, and let them know if it did not. This will also often help solve your problem. Sharing information is what really gets the problem solved.
Addressing your issue now, I can tell you this much: if you don't get systematic about addressing your issues, you are going to drive yourself nuts and end up selling the motor to escape it. You aren't sure if this is your problem or not. You stated in your original post that the motor was running fine until you put an extremely thick mix of fuel in it. That should not have had an affect of this fuel connector. I described what you should do to rectify that problem in that thread. Don't know if you read it. If you didn't do any of that stuff, I seriously doubt this connector will fix your problem, but for you sake I hope it does, we all root for success!
If that is the connector plugging into the motor, you will not be able to blow through the fitting. It has a spring in it that is depressed when you connect it to the motor, and then fuel can pass through it. If fuel isn't coming out of that crack your are describing while you are trying to run the motor, it is probably not your problem at all. But if you just want to go buy one, it will be online or at a Suzuki dealership. You probably cannot make one yourself as you described.
Best of luck to you!
