Flex Fuel kit question

The car has a flex fuel kit installed by the PO but i have never used any flex fluel (E85) ever since I purchased the car 3 years ago.
I have only put may be a 1000 miles or so since then, busy at work
Started noticing, car choking down when stomped on the gas and mechanic just said needs a fuel pump/fuel filter and a MAF sensor.
Have no idea what kinda FP/FF the previous owner used but do i need a special FFP and FFF (flex fuel pump and filter) specically designed for FF good for both types of fuel?

Thanks

Lifted the car yesterday and here's what I see --- no numbers on the fuel pump unless they are on the top and not visible unless it's taken off (doing it later today)
Can someone ID this pump for me? Several such pumps are on Ebay ranging from $43 to $200+ and the expensive one's have lettering on them but this one doesn't.
I am gravitating more towards a cheap FF certainly not designed for flex fuel?

Clogged as heck, no wonder car didn't run right....Hope this fixes the choking problem
Ordering another one knowing well, the fuel pump might be next (hard work it probably did to push the fuel through the clogged filter)

Yes, the FPR is in the engine bay, you surprised?

I am also finding out there's so many things that's not done right along with few lose stuff/wires hanging around too

I have promised myself, slow and steady, I am going to fix this ***** and make it look and drive the way it should be LOL

This is the fuel pump, a mercedes unit and I am trying to find out what model it fits but it does begs a much bigger question, why did the guy not install a dual mode fuel pump (flex fuel/gas) and why this pump? Cost? Shall i upgrade to flex FP even though I have no plan on running the E85?

Thanks

This is OE/"pierburg", for most 97-03 MB models, with (57.8psi) at (3.8bar),
maybe that guy create the flex with same stock fuel rate!!,,

did he change the fuel rail?, or still stock???

I will confirm that, don't think he changed the fuel rails but he did install M113K injectors though.

Fuel rails, can you make it out here?




2 lose wires, one with the black plug and one just cut straight and both coming out from the same wiring harness, coming from the driver side fender?




Same as the second picture and same 2 wires




The white plug, coming from the front driver fender, side marker light plug?

Looks like this is N/A M113 stock fuel rail,

he can't install M113K injectors with stock N/A m113 fuel pump!!, cause M113K injectors flow rate is (396cc = 38Lb/hr) with (75>>80psi),,

did he install an additional FPR.??, can't tell from the pics..??

I see, looks like he made everything standalone flex F/A lambda/mixture ratio!,

to confirm everything properly;-
prefer if you can check what's the p/n of the fuel injectors & O2 sensors, as well as the ECU e-prom file..

O2 sensors I probably can...
Fuel Injectors--- I am not sure how?
ECU e-prom----- how do I do that....car was dyno tuned by Eurocharged, call them I guess and see if they have the file, right?

About injectors, usually can figure out from the injectors colors:-
*N/A M113 5.4L comes with "green" or "yellow"
*M113K comes with "black" or "navy blue"

if you can contact to the previous owner, he can send you the ECU file by PDF or schematic data file,,
or even "Eurocharged" can send you the tune file by VIN#, or via by log me in/any desk..

I will check the injectors when I do the plugs in few months
Will contact EC see if they would give me the file but the guy doesn't work there anymore and won't reply to my messages either.

Ran into a little snag, either over torqued it or must not have aligned it right but needed a new end fitting. Called Summitt racing, spoke with Easton who was kind and patient enough to help my ignoarant axs to figure out what I needed and sent me the fitting right away
