Hello,

I am currently running dw65v fuel pump that sits in fuel tank. I've been told that i would need secondary inline fuel pump to gain some more power.

I wonder if there is something more to be aware of than adding a pump and powering it up from main pump plug by 12v relay.

Is that plug and play mod? I wonder if stock fuel pressure regulator and ECU map needs to be changed to adjust to the new pressure that will increase i guess.

Any tips and know-how are much appreciated. Thank you.

You need stable power supply at second pump, running 2 pumps from original wire is not good idea. Voltage will drop and pump does not have full performance. Check datasheet.

Yes, sorry, my bad.

Its a 2000 Audi TT with modded 1.8T BAM engine. There will be a efr7163 T4 twin scroll turbo. I believe the fuel system is return type. Target power is somewhere around 450hp, i've been told that dw65v will not handle it properly and in-line pump would be needed.

I want to add it at my own but i just started my moto journey so i prefer to ask twice..



I though the fabric fuel pump harness is more than enough for both of them but then i checked their power consumption and the fuse..

So i will definitely add "standalone" harness straight from the relay box.

Just to be sure i will replace current 20 year old FPR to new Bosch one.


Thank you guys.
