Product FAQ

Fitment summary: Fuel Pump Assembly; OE/OEM 1644701994; for Mercedes-Benz, W164, the listed year range, the matching engine or trim, the matching installation position. Please verify the OE/OEM number and original connector before ordering.

Will this Fuel Pump Assembly fit my vehicle?

This Fuel Pump Assembly is intended for vehicles that match OE/OEM part number(s) 1644701994. Confirm the vehicle details and fitment notes: Mercedes-Benz, W164, the listed year range, the matching engine or trim, the matching installation position. Model names alone are not enough because connector style, year range, trim, engine, and installation position can vary.

How do I confirm OE/OEM compatibility for 1644701994?

Use the number printed on your original part first, then compare it with this listing's SKU, MPN, OE/OEM numbers, and product photos. OE number matching is usually more reliable than matching only by vehicle model name.

What should I compare before ordering this Fuel Pump Assembly?

Compare module shape, fuel outlet direction, electrical connector, sender layout, tank fitment, and pressure specification. If any detail differs from your original part, contact us before ordering or installation.

What symptoms can a failing Fuel Pump Assembly cause?

A failing or incorrect Fuel Pump Assembly may cause no-start symptoms, long crank time, weak fuel pressure, hesitation, or fuel level reading issues. Symptoms alone do not confirm fitment, so verify the OE number and physical part details before purchase.

Can I get fitment help before ordering?

Yes. Email your VIN, original OE/OEM part number, vehicle year/make/model/engine, product link, and clear photos of the original part and connector to info@NexuParts.com. We can help compare it with this Fuel Pump Assembly.

Can this part fit the same vehicle model but a different year or trim?

Possibly, but it should not be assumed. Many vehicles use different connectors, modules, sensors, or left/right versions across year ranges, trims, engines, and market regions.

Is this a new replacement auto part?

This listing is for a new replacement auto part supplied by NexuParts unless the product page explicitly states otherwise. It is selected by OE/OEM number and fitment reference, not by vehicle model name alone.

What should I check before installation?

Before installation, compare the new part with your original part side by side, especially module shape, fuel outlet direction, electrical connector, sender layout, tank fitment, and pressure specification. Installed, modified, damaged, or used electrical parts may not be eligible for return unless defective or incorrectly shipped.
