Will the AEM in-tank fuel pump fit my car (e.g. Audi S4 B5, A4 B7 2.0 TFSI)?

In general yes. The AEM high flow in-tank pumps are universal and fit most factory pump assemblies. We recommend showing the pump to the technician who will install it, as they will see immediately whether it fits your pump module. There are some cases, such as certain 4x4 vehicles with saddle tanks, where it cannot be used. We usually sugest DW solutions. Ask our team for more details.
