Renault Megane Fuel Pump: Specs, Fitment & Common Faults
A genuinely severe, well-documented HPFP fault on the 1.5 dCi — with real, dramatically varying quotes (£1,300-£3,500+ dealer vs ~£1,200 independent vs one case fixed for just £100).

OEM Part Number: 172020029R (as quoted in catalogue listings — confirm via VIN) — aftermarket fuel pumps Bosch 0 580 203 318 / Hüco 133439
| Fuel pumps / feed units (aftermarket) | Hüco 133439 (complete feed unit with sender, petrol); Astemo 2503170 (complete feed unit with sender, petrol); Hüco 133170 (complete feed unit with sender, petrol); Hüco 133171 (complete feed unit with sender, petrol); Bosch 0 580 203 318 (in-tank pump); Hella 8TF 358 146-841 (feed unit with sender, 4-pin); Hella 8TF 358 106-511 (bare pump, 2-pin); Magneti Marelli 313011300018 (in-tank pump, diesel, 4 bar / 180 l/h, 12 V / 10 A) |
|---|---|
| Types & variants | Three petrol modules are listed under Hüco (133439, 133170, 133171) with Astemo 2503170 matching the 133170. The Magneti Marelli 313011300018 is the only unit marked diesel and is a bare in-tank pump at 4 bar / 180 l/h. Bare petrol pumps at 3-3.4 bar / 95-100 l/h (Ridex 458F0040, 458F13818, Energy G10007, ESEN SKV 02SKV227) are MPI-type cartridges sold without the housing. Original Imperium 4017 is a rubber-bodied pre-supply pump with 8 mm angled connectors. |
| Genuine (OE) numbers quoted | 172020029R (Hüco 133439); 8450008680 (Kamoka 8410005); ERA 770162A lists repair kit 770162 |
| Fitment notes | The petrol TCe engines take a complete module with sender while the dCi diesels use a lift pump, so the two are not interchangeable; a bare pump can go into the old housing where the sender still works, but the early and late petrol modules (133170 versus 133171) differ, so match the Hüco number to the build date. The 1.6 E-TECH hybrid is listed under the same catalogue but no product is marked specifically for it. |
A Genuinely Severe, Well-Documented Fault on the 1.5 dCi — And a Real Cost Comparison Worth Knowing — Renault Megane Fuel Pump
If your Megane has the 1.5 dCi diesel engine, particularly an early example, this is genuinely worth understanding given how consistently and severely it's documented: the rollers inside the high-pressure fuel pump can disintegrate, sending metal filings throughout the entire fuel system — the rail, all the injectors, and the associated pipework — contaminating everything in its path. This is confirmed across numerous independent forum threads as a known, recognised fault among mechanics familiar with this specific engine, not an isolated horror story.
It's worth getting a second opinion and a specialist assessment of exactly what's failed before accepting the most expensive quote as the only option — while genuine metal contamination throughout the system does sometimes require the full replacement, it isn't automatically true in every case, and a proper diagnosis first can make a meaningful difference to the final bill.
Renault Megane Fuel Pump: A Part That Fails at the Worst Possible Moments
This is one of the more inconveniently timed failures the Renault Megane can have — it tends to strand drivers mid-journey rather than politely failing while the car's parked on the drive. Recognising the early warning signs buys real time to sort it before you're stuck somewhere inconvenient.

Renault Megane Fuel Pump: What It Does
Delivering fuel from the tank to the engine at the correct pressure for combustion is the Renault Megane's fuel pump's whole job. It lives inside the tank itself, submerged in fuel, which is exactly why replacing something this small is a more involved job than it looks.
Renault Megane Fuel Pump: Generations & Engines: Fuel Pump Type
| Megane I/II (1996–2008), most petrol | Petrol: typically a single in-tank low-pressure pump; some later or higher-output variants may add a separate engine-mounted high-pressure pump for direct injection — confirm your exact engine |
|---|---|
| Megane II RS 225/230 (2004–2009), 2.0 turbo (F4R) | Petrol: typically a single in-tank low-pressure pump; some later or higher-output variants may add a separate engine-mounted high-pressure pump for direct injection — confirm your exact engine |
| Megane III (2008–2016), 2.0 TCe petrol | Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump |
| Megane III RS 250/265/275 (2009–2016), 2.0 turbo (F4Rt) | Petrol: typically a single in-tank low-pressure pump; some later or higher-output variants may add a separate engine-mounted high-pressure pump for direct injection — confirm your exact engine |
| Megane II/III, 1.5 dCi diesel | Diesel: in-tank lift pump feeds a separate engine-mounted high-pressure injection pump (common rail) — never interchangeable with the petrol pump |
| Megane IV (2016–present), 1.3/1.4 TCe petrol | Petrol (direct injection): in-tank low-pressure pump plus a separate engine-mounted high-pressure pump |
