The Fast Daily – A C5 Allroad Story – Part 2

I’ve had a NIB DW300 fuel pump kicking around for the past year, so I decided to put it to good use. I turned an adapter sleeve out of aluminum to fit the pump snugly in the factory sender housing.

I then soldered the DW connector the sender lid.

For anyone who wants to do a similar install, I found this pre-filter sock at Autozone that fits great.

High quality audio has always been a high priority for me. I’m not looking for a setup that will rattle teeth, just something that will let me accurately hear the music. I found a Polish company, Basser, that makes custom fit subwoofer boxes. Considering the price, the quality of the box is amazing and the fit is perfect. The Audi trim ring really kicks up the bling factor too. It’s a bummer that the carpet isn’t a better color match, but oh well…

In order to fit the box I had to get rid of the factory tool box and relocate the air tank. The only place I could find that would fit the air tank was the spare tire well, which meant I had to get rid of the spare… I welded some nuts to the chassis and turned some standoffs to securely hold the tank.

I was hoping to reuse the factory air tank brackets, but it looks like they’re bonded to the body with some sort of wax? 10 minutes with a heat gun wasn’t enough to get it to budge, so I gave up and just left it in place.

I mounted the amp on a piece of 1/2″ HDPE that was held in place by the nut which secured the spare tire.

I binned the factory amp and installed a MBQuart NA2.400.1 in its place.

I measured the the stock pre-amps and found that they’re pretty low voltage, but they work well enough to run straight into the amps.

I ran a 4ga wire through a 150A fuse into the spare tire well.

I’m going to use this junction point to upgrade the fuel pump wiring and supply power to something fun that the air tank will help with

(more on that later).
