I was hoping I could just unbolt it and the fuel filler and slide it over to the passengers side some or hold it up with a 2x4
The fuel pump looks like its at the back under the bed and not under the cab
(the left tank is a standard and the right is a 36 gallon like I have)

It ended up being easier to drop the tank (I'm working alone with just floor jacks in my garage)
I only figured that out after unbolting the bed and trying a bunch of ways to get it to lift.
As Mike pointed out: super easy to damage something that way

Would I be smart to order a new OE pump and have it fit and ready to go with the DW400?

I did mainly to get the flow rates testing so we know what it flows inside our trucks.
But its super easy to install yourself in the fuel pump assembly

Here is the DW400 flow numbers inside the OEM fuel pump housing tested at the voltage commanded by the Whipple tune (it ramps up for the fuel demand)
Before the internal check valve is installed
