I believe the second pipe on the Z991 is for the fuel return line from the regulator on the fuel rail of turbo models. The Z924 / Pump (NA) assembly includes the regulator and spills back inside the tank and so has no fuel return line to connect. It also includes a fuel gauge sender unit... The Z991 has no sender unit (it is a separate unit under the RH inspection panel on the 4B11T / RA / Evo) and also requires you to disconnect a suction pipe inside the tank not present on NA tanks...

Turbo tanks are supposed to be 55L and NA tanks are supposed to be 59L - unless that's a typo in the TIM. I've never filled with more than 49L from "empty"... I only have info till MY11 so YMMV.

CORRECTION: Turbo's have a 55L tank, not a 50L tank. Corrected in text as no strike-through enabled...

P.S. Turbos also have a pre-filter on the end of the suction pipe fitted inside the tank. You'd have to put your arm right in to get to it...!

Worst thing to can do when replacing the filter is to do it with a full tank
Get the tank as empty as possible
There is plenty of safety precautions to be done but by far the biggest is to have the least amount of fuel in the tank.
The filter sits inside a cradle
That cradle when you lift it leaks fuel everywhere
So do it slowly and carefully and turn it on a n angle a bit and you will see fuel pouring out of it.

This is not something for the faint of heart and if you can't tell the difference between a socket and a spanner then better off to get it to a mechanic to repair it for you

Nope
Single fuel pump

The 2nd hose adaptor is for fuel rail return

The fuel pump on the Evo X is the same as the CY lancer in dimensions. Not sure the fuel pressure if the Evo X , but the Lancer is a boring old 100LPH
You can take a E85 fuel pump for the Evo X and shove it in the lancer. The fuel pump motor itself is also the same in the RA.
