2015 Subaru XV fuel pump: purpose, upkeep and when to replace

Yes, the 2015 Subaru XV uses a fuel pump. Subaru’s workshop material for the 2015 XV/Crosstrek (Fuel Injection/Delivery, FU section) specifies an in‑tank electric fuel pump module on the 2.0‑litre petrol FB20, and the Subaru parts catalogue lists the complete in‑tank module (commonly referenced under 42021FJ0xx). Diesel EE20 models also run a low‑pressure in‑tank pump and an engine‑mounted high‑pressure pump for the common‑rail system. So the fuel pump is absolutely relevant to this model.

On the XV, the pump’s job is to supply a steady flow of fuel at the correct pressure to the injectors so the engine starts crisply, idles cleanly and pulls smoothly up the road. The in‑tank design keeps the pump cool and quiet, and you’ll often hear it prime for a second when the key’s switched on.

It’s not a regular “every‑service” replacement item, but it does appreciate a bit of care. Keeping at least a quarter‑tank of fuel helps cool the pump. For petrol models, the fine filter is built into the in‑tank pump module, so there isn’t an external filter to change as a normal service line item
