Fuel injector interchangeability

[Austin Calise]

Eric, I do know for a fact they are different the 3B injector has a single port while the AAN injector has 4 ports. They also have different flow ratings 3B is from what I've gathered  29lb/hr 310cc @3bar(stock FPR) while the AAN is 30lb/hr 323cc @4bar(stock FPR) there is conflicting info floating around on the net about what the flow for the AAN injectors is but I believe that is correct. So there is some difference. With all that said if your son is looking for an AAN injector I have two spares and I would gladly send one/both out for the cost of shipping.
