    E60 535I LPFP upgrade help

    Hi,

    I initially took out my LPFP to do an inline upgrade.. well that failed as the E60 is a bit different when it comes to the low pressure fuel pump. I decided on going with AEM 320 because a member on n54tech @skysurfer posted a while ago that he had successfully done it and it had been running perfectly. With the help of some pictures provided by the person who did it for skysurfer, I was able to get through roughly 85% of the process. I am however stuck at the most import part, Where does the AEM get power from. I have a few pictures of skysurfer's completed setup but it's at a weird angle and I am unable to figure it out.
    Can anyone assist? My car has been sitting now for over 2 weeks(although parts were part of the reason)

    Here is skysurfer's completed set-up for reference.

    You're going to need to tap the wires going to the stock lpfp

    Was gonna say, you're gonna use the only power source that's back there so get ready to modify the OEM LPFP power cord. The whole system works off of voltage, so if you're not comfortable cutting/splicing wires, I'd take it somewhere that can do the job right for you so you don't have any issues.

    You splice/crimp to the stock LPFP wiring. As noted it’s all based off voltage. A cleaner way of doing it would be to pull the stock wires from their harness in the top hat, then solder your inline wires there and plug everything back in. Makes for cleaner work, though just splicing them is obviously less time consuming. Credit goes to Wedge for that idea, that’s how my FFTEC pump is wired.

    I was wondering how the pump held up. I'm looking to do this upgraded in my 535i but with the newer AEM 320e pump since I want to start running a E50-60 fueling mix. Let me know. Thanks.

    The pump should be able to handle E60 fine and has not been an issue since I've installed it. Although I have been running nothing but 93 for this winter as the HPFP still does not like high ethanol content if its anywhere close to freezing. Chicago has been below freezing for the entire winter I would say lol

    Damn that's cold. Well I'm probably going to get the new AEM 50-1205 pump installed in the next couple of weeks and change up to a E50 map. Should get me a nice bump of power now that I just got my Dr Euro ***less DP's installed.

    I had the AEM 320 installed last week. Not a bad mod and I live in south GA so E85 is close by. All seems well so far. W/ JB4 8 gallons of E86 should be just fine. My car is a beast with the E85 mix.
