And to finish the weekend off, Cluster swap
Wow @CE9311 - you've been busy!Installed the 6.4 Intake. Yet to wire in the MSD window switch for SRV function. Initial tests with no tuning show increased bottom and mid range power. Have not tried a launch yet as my tires already are bald-ish. (waiting to get every ounce of life outta them before putting new tires on)
Just now saw this opps.
Saved yourself a lot of hassle!Fuel pump died 30 seconds before I would have been driving it on road.
The way the fuel pumps work is as follows, fuel enters the reservoir of the main fuel pump module (driver side). The main fuel pump module pumps the fuel through the filter to the auxiliary fuel pump module (passenger side) through a supply line inside the fuel tank. The fuel pressure regulator inside the auxiliary fuel pump module regulates the pressure at 58 psi and sends fuel to the engine.
All unused fuel that is not sent to the engine is fed through a venturi at the bottom of the auxiliary fuel pump module. This creates a low pressure siphoning effect and draws fuel from the passenger side of the tank and transfers it to the drivers side tank via siphon hose inside the tank. While the vehicle is running the fuel in the passenger side of tank is continuously transferred to the drivers side. Fuel will continue to fill the drivers side tank till it reaches the bridge section and then starts to spill over to the passenger side.
Either fuel pump can be replaced without replacing the fuel tank ... they just need to follow the Service Guide procedures.
The Main Fuel Pump Module must be removed for Auxiliary Fuel Pump Module removal
The Auxiliary Fuel Pump Module must be installed before the Main Fuel Pump Module.
Whenever a fuel pump module is serviced, the rubber O-ring seal must be replaced.
The fuel tank check valve and control valve are used to reduce emissions due to the venting of vapor expansion within the fuel tank.
The fuel tank check valve and control valve are non-serviceable components of the fuel tank assembly. The fuel tank assembly has to be replaced if these valves are not functioning properly.
One fuel pump, two senders of sorts. The passenger side holds the psi regulator and uses the returned fuel with a venturi effect to siphon fuel out of the pass saddle tank into the driver side saddle tank. Neat design.
