Well I just got done finishing up installing my new dual inline bosch 044 pump and surge tank setup that will fit the B5 A4/S4. It uses dual 044 inline pumps and 1 intank pump(stock or upgraded). The setup was custom built for me by the guys at 034 Motorsport. Nice thing is that the dual pumps are not much louder then the intank pump and really cant even be heard while the car is running unless sitting under the back of the car. With a little work the rear cover will actually go back on so it hides the pump/surge tank setup.



2nd OEM filter with -8 line and AN fittings


-8 feed line with heat sleeve

 

You're gonna eventually break the sound barrier with all the modding you do to that thing. Much better location for the fuel filter though.

 

Yeah it is unless you are running an exhaust. lol


I actually still run a filter in the stock location just to make sure nothing big enough from my stock tank/pump end up damaging my dual pumps.
