Audi S6 4.0T Upgrading HPFP's And Fuel Lines For E85 

THANK YOU for all the DIY videos you have done! It has really helped me out work on my S6 with similar mods. I have read SRM suggests running the E85 sensor on the drivers side but have not confirmed that with them. Keep up the awesome job you are doing and making these great videos!

She was ripping at the end!! 👌🏽

Wow man! Really great work. I'm preparing to do this exact same work to my 13 S6. Wish I had somebody like you to lend a hand lol. Pretty intimidating but also simple enough. Thanks for making this

I like all our videos. I've used them for reference for the past year. I just wanted to ask about long term reliability that you would expect from an S6. I probably drive 20,000-30,000 miles a year for work and have always loved the S6 and the 4.0T. I'd probably just to a TCU tune and Stage 1 ECU tune and not touch it for a long time. And then if the turbos needed replacing, I'd definitely put in some RS7 turbos. How comfortable would you be using an S6 as a daily commuter long term and what recommendations would you have for making it as bulletproof as possible?

Great video man! Wish this was up when I was installing mine 😂

Nice product, seems like a good idea 👌

Love the content man! I'll be getting the kit soon. Once they actually compete my last order. Lol

you make it look SOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO EASY...

Where on the ecu do you pin the flex sensor at ?

Did you remove the factory line that feeds from passenger HPFP to driver side HPFP out of the engine bay?

On 93 with Stage 3 apr....would just replacing fuel lines add any benefits?

Great video with excellent tips! I noticed that you did not show the priming of the fuel pump/system. Is that because the system is self-priming or is there a process for the priming of the pump using VCDS?

Do I need to upgrade the HPFP even if I don’t go with ethanol. I have ST1 turbos, ECS inlets, cartless downpipes!

Which fuse did you pull for the lpfp? Is it necessary for the camshaft to be on its lowest point for installing the hpfp? Love the video, really helps a lot! Thank you

Great video! Have the same kit :)

Thank you! Really helps to see this installed vs just hearing everyone talk about it. Once you have this installed, can you still use regular 91 octane gas if desired? What do you mean when you talk about an e50 blend?

Thanks for the great video! Gives me the idea to upgrade my lines too...But I'm looking to piece together my own kit. So far the only trouble I'm having is finding the adapter from the LPFP which you call a "pushlock" to -6an fitting @7:04 of the video...Do you know if this adapter goes by another name? Also I know that the fittings you are using are -6an, but are they just male -6an to -6an? Or is the threading's in the HPFP's themselves a different size? Thanks for any info you can share, I appreciate your help in advance! Cheers!

I'll bring my by TOMMOROW for the hook up......LOL

I’m using HPtuners for tuning and it has ethanol tables. Wondering if pinning the sensor works for Hptuners also?

Hello i have 2013 a8l and i have white smoke coming from the tailpipes after it warms up,what will cause this

Was is flex where u can run both e-85 & unleaded 93?

Is it a boo boo to do the HPFP while they are still on the car?

Do you happen to have that xml file??

How many whp did you get by switching to E85?

Hello i have a question,i have 2013 a8l and when it warms up white smoke comes from the tailpipes,what might cause this

Do you need to upgrade any of those parts or can you just get e85 tune?

What is the torque spec for the fuel pump after you swap out the and go to the Autotech plunger?
