Parts for your 2008 Mitsubishi Lancer-Fuel pump

2008 Mitsubishi Lancer Fuel Pump — Purpose and Service Advice

According to Mitsubishi’s Workshop/Service Manual for the CJ Lancer (Group 13A – Fuel), the 2008 Mitsubishi Lancer uses an electric, in‑tank fuel pump module. The OEM parts catalogue for CJ/CY models lists a complete pump/sender unit with strainer and seal, and well‑known repair manuals for 2007–2015 Lancer models likewise describe an in‑tank electric pump. So yes, a fuel pump is absolutely relevant and fitted to the 2008 Lancer, including common 2.0L 4B11 and 2.4L 4B12 petrol variants (and a lift/low‑pressure arrangement on applicable diesel markets).

On this Lancer, the fuel pump’s job is to deliver a steady, pressurised supply of petrol to the injectors, typically in the 300–400 kPa range. Housed in a plastic module inside the tank, it includes the electric pump, a pre‑filter/strainer, the level sender, and often a built‑in pressure regulator. Because modern EFI relies on tight pressure control, a healthy pump keeps cold starts crisp, throttle response clean, and highway overtakes drama‑free.

There isn’t a strict replacement interval in the Mitsubishi schedule, the pump is usually a replace‑when‑needed item. Still, a few habits will help it go the distance: avoid running the tank near empty (the pump is cooled by fuel), stick with quality petrol from reputable servos, and replace the tank seal if the module’s ever removed. If you’re chasing drivability niggles, it’s smart to check fuel pressure at the rail, scan for codes like P0087 (fuel pressure too low), and verify the pump relay and connector are clean and tight.

Common signs the 2008 Lancer’s pump is on the way out include:

• Hard starting, especially after an overnight sit
• Hesitation or surging under load, or at higher rpm
• A pronounced whine from under the rear seat area
• Low measured fuel pressure or lean trim numbers on a scan tool

Replacement is straightforward for a competent DIYer: disconnect the battery, relieve fuel pressure, lift the rear seat base to access the service cover, label the quick‑connect lines, then release the lock ring and lift the module out. Always fit a new tank seal/O‑ring, keep everything spotless to avoid introducing debris, and double‑check the float arm path. Many CJ Lancers have an integrated filter within the module, the external “serviceable” filter isn’t present, so replacing the whole assembly is often the sensible fix when pressure or noise issues persist.

Does a 2008 Mitsubishi Lancer have a fuel pump?

Yes. Technical references including the Mitsubishi CJ Lancer Workshop Manual and OEM parts listings show an electric, in‑tank fuel pump module fitted to 2008 models. It supplies pressurised fuel to the injectors and incorporates the level sender and strainer.

How long does the fuel pump typically last on a 2008 Lancer?

Many last 150,000–250,000 km or more. Lifespan depends on fuel quality, how often the tank’s run low, heat, and electrical health. A rising pump whine, lean codes, or pressure drop under load usually signal it’s time.

Can just the fuel filter be changed, or is it part of the pump?

On most 2008 CJ Lancers the fine filter is integrated within the in‑tank module, with only the strainer considered a service item. When pressure or flow is below spec, replacing the complete module (pump, filter, sender, seal) is the common approach.
