Blown F-150

Motor is in the truck and running like a champ. I'll need to be patient as I get through the break-in period, I can't wait to turn up the wick!

- Upgraded in-tank pump (swap to a return system)
- Radium fuel Regulator

what is the upgraded fuel pump with a return line?

Is this a fix for fuel dilution issues that some of the 3.5 ecoboost engines experience?

I never had a issue with fuel in oil, so I have no idea if this will have ANY impact. the return system is for better fuel delivery at higher power levels and to keep fuel circulating to keep the upgraded High Pressure Fuel Pump as cool as possible.

The return system is a "custom" build. I am running a Walbro 450 in the tank with the stock regulator removed. So the pump runs to a Injector dynamics filter. the filter runs to a Radium Pressure regulator, all via a new -10 AN line run from the tank to the engine bay. The regulator runs to the HPFP and uses the OEM line to return fuel to the tank. So I've added a fuel line, put in a new AN fitting for the new line in the tanks fuel hat and added a Fuel filter under that truck as well as a egulator in the engine bay.

300 miles on the new motor and 2nd oil change just done. Running pretty awesome and now I can start working with the tuner on getting things base lined.
