One easy way is connect this to your fuel fill line then connect the return fuel line to it.

That is definitely worth a try. Anywhere else a fuel line is close to the engine?

It creates a constant flow of fuel throughout the system instead of a "dead-head" style system where the fuel sits in the lines for a prolonged amount of time in an idle situation.

That's interesting. So basically the fuel that is getting too hot running around the motor will be constantly on the move instead of being stagnant. I understand the theory. I guess I don't know how the return is hooked up now with the VST tank. Would I just want to hook the return to the vent lind of the tank vs. the fill?

Any possibility of running lean at WOT due to returning to the tank vs. whatever method is being used now?

DownandDirty

It won't run lean because it will have constant fuel flow as well as more steady fuel pressure. This system still has to have a regulator in line to maintain the proper line pressure (a fuel log style regulator works great). Typically it will be just after the carb inlets on the return side. This keeps the pressure constant but also allows the fuel to reach the carbs in whatever capacity needed. As far the return line entering the tank, you will more than likely have to make a new entry to maintain the proper ventilation. One of the performance shop guys on here could give you a better diagram and layout for your application. Good luck.

Yeah, your confusing me somewhat, i have the MPI, what do i need to do.

DownandDirty

My mistake cloudmaster, I missed the mpi and was under the impression it was carburated based on the post about the return system. I'm not certain but I believe the mpi already has a return style system due to the level of fuel pressure required to run. I have extremely limited knowledge on fuel injected systems won't be of much help. Sorry for the confusion, just trying to help.

Was everyone elses's post on a carb model or MPI? What do I need to do for an MPI?

I'm going to try this.............
