Does anyone have an opinion on the regulated fuel returns and the air dog? One of the return kits feeds the fuel from the back of the heads. Is this better than the front fed kits for eliminating cackle? Also if the air dog is really that great and eliminates all the air from the lines, then is there a need for the fuel kits? It seems most of the mods for this noise has to do with eliminating air. /ubbthreads/images/graemlins/shrug.gif

Part of the noise has to do with eliminating air, and part has to do with making sure that all 8 injectors have sufficient fuel flow and pressure to operate correctly. The AirDog does a great job of the former and the fuel system kits a great job of the latter.

We've run our fuel system kits in just about every possible flow pattern. We have not seen any difference between feeding the front or the rear on the drivers side. If the fuel system is up to snuff and delivering sufficient fuel flow and pressure, all of the injectors will have the fuel they need.

Hope that helps...
