HFP-439A Fitment

HFP-439A Description

HFP-439A is a new Quantum gas listed for BMW E31/32/34 OEM Replacement Intank Fuel Pump 535i 750iL 850Csi V8 V12 -2 Pumps. This page is intended to help match the BMW fuel system part by part number, vehicle application, and the visible product details shown in the listing. Because BMW fuel pumps, sending units, and high-pressure pump assemblies can vary by chassis, engine, production date, tank side, and connector layout, the part number should be treated as the most important fitment signal.

Before ordering, compare the number on the original component with the primary number on this page and review any cross-reference numbers shown below. Also verify the fuel type, pump location, electrical connector, line fittings, seal style, and whether the vehicle uses an in-tank module, sender assembly, inline pump, or engine-mounted high-pressure pump. Key details include fuel type: Gas.

Fitment Type: Direct Replacement If the vehicle has had previous fuel-system work, confirm that the installed pump has not already been superseded to a newer BMW or supplier number. A small difference in connector indexing, fuel level sender arm, pressure rating, or tank orientation can prevent a similar-looking pump from fitting correctly. Cross-reference numbers captured for this listing include 1183389, 16141183389, 16141183178, 16141180318, 0580453021, 161411831, 405-052-005-001Z, 405052005001Z.

Common reasons to replace or inspect this type of BMW fuel pump part include long crank time, no-start conditions, low rail pressure, unstable fuel gauge readings, intermittent stalling, fuel starvation under load, or diagnostic trouble codes related to pump control or fuel pressure. Those symptoms can also be caused by relays, wiring, clogged filters, tank contamination, pressure regulators, or control modules, so basic diagnosis is recommended before replacing parts.

During installation, work safely around fuel, relieve system pressure where required, and inspect the tank opening, locking ring, gasket, strainer, fuel lines, and electrical terminals before reassembly. Use the product photos, part-number list, and fitment table on this page together with the vehicle VIN or original component label. If two BMW listings appear similar, choose the one that matches the OE number and physical layout rather than relying only on model name or year range.
