Audi A3 Fuel Pump – APR High Pressure Pump (2015–2020). A proven HPFP upgrade that increases fuel volume to keep pressure steady when your build demands more.
By increasing the pump’s internal displacement, this unit delivers up to 37% more volume than stock, adding headroom for higher‑output setups while helping maintain commanded pressure. APR machines the plunger and barrel from bearing‑grade stainless, with a DLC‑coated plunger. Tolerances: 0.00004 in (dim.) and 0.00005 in (geom.). It uses an upgraded, weight‑matched spring and genuine Hitachi OEM parts. Each pump is assembled in‑house and machine‑tested before shipping.
