Fuel filter location

Rcar5220 · 06-11-2015, 10:10 AM

Hi, struggling to locate my fuel filter, could anybody tell me where it is on the car?

The car is a 2008 318i 2litre

Thanks!

It's in the fuel tank as part of the fuel pump. It's not separately replaceable from the fuel pump; you have to replace the whole pump. That said, I don't think under normal circumstances (i.e. mileage) it needs to be replaced. It's a lifetime part.

I've been having trouble with the fuel pump, so I was starting a process of elimination!

Are the fuel pumps an expensive part, and easily changeable?

They are around $150 US. Very easy. The access is under the rear seat. Pull the seat cushion, remove the access cover (driver's side for a UK car), release the retaining ring, pull the pump and replace. There is a bit more to it than that of course, like unplugging the battery, unplugging the electrics and fuel lines, etc. There is a recent DIY on the procedure in the DIY section.

According to Bentley's the fuel filter is 'lifetime' and integrated into the LEFT SIDE FUEL LEVEL INDICATOR

I recently replaced mines since it had a crack in it, which was leaking fuel. Under rear seat on the driver side. Once you open the hatch you will see the assembly. Part number is 16147163296 for 335i. On mobile so unsure what it would be for a 2008 318i, I'm assuming not us spec.

So...is the fuel pump under the seat the dreaded hpfp that everybody fears will go out? I always hear about that and some talk about the lpfp...do these cars have two pumps? Really, it is easy to change and not that expensive relatively so why has that been a big fear point with people? I've had fuel pumps go out in a couple cars before 90k, left me stranded, but for a car not running at all was not a big financial setback. Someone please clarify this?

The one in the rear is the LPFP. The HPFP is under the hood.

Hpfp is under intake manifold. If you pull the rear seat cushion you will see two circular holes. The hole on the driver side has the fuel filter/regulator assembly, and the one on the passenger side has the low pressure fuel pump.

If your having issues with your fuel filter or regulator might as well replace/upgrade the lpfp since you have to mess with it to replace the fuel filter/regulator assembly. Hpfp was replaced twice so far under warranty, so I've personally haven't changed it. In my opinion the real fear point is what you have to go through just to get to the part your trying to replace. Or having to use a specialty tool to get that hatch covers off, you can use other methods but just easier to use a tool designed to open it.
