how often are people replacing fuel filters

[discomatt69]

As the title says how often should a fuel filter be replaced, D4 3l,
I get that over replacing is not good because it opens the system to contaminates but how long is to long.
The reason I ask is the D4 has just had a service and pre trip inspection before we head off on a 15,000km trip towing the van, the fuel filter was not replaced and hasn't been for about 3 years but the last 2 years have seen minimal km

I would have had it done,one less thing to worry about.

Although they are sort of relatively easy to change,so maybe pack a spare for the trip.

I've done over 70k since buying my D3 and not changed it yet but will add one to my next parts order.

I change mine around 20-25,000 klms.
If I were you I'd change it prior the big trip and definitely take a spare in the event you get some bad fuel.

10 or 20k service for me. Usually depends on whether I have one on the shelf and the time.

I've done mine every 2years regardless of km. I use only Mahle filters. I'd strongly advise to change yours at that age and km, but not on your back in the sand on a 43deg day in Esperance (ask me how I know) they are easy to replace, just note that when you pull them off you do get the filter coming out full of diesel, so you will be spilling some as you have to tip it sideways to clear the crossmember and tank. A tip when you have a new one in, cycle the ignition a few times and let the lp pump in the tank prime the system again, this will limit any air pocket related engine stalls, these sometimes take a bit of cranking to get engine re started, and can put a bit of strain on your battery(ies)

I plan to change my fuel filter out every 50,000km. Every now and again I'll need to change it out early due to clogging, but I always travel with a spare as you never know when you'll get a load of dirty fuel

The other part is the sensor on the top fails and gives false readings cheaper to replace than repairs

***** of a job to swap the whole assembly out, so I ended up swapping the water sensor between units. Best fix ever. I was constantly getting the water in fuel errors.

I do my filter every couple of years or around 40,000km. I feel every time you open the sealed system you risk contamination so I try to not over service it.

I'll be the odd 1 out here, I've replaced mine once a year or two ago I've done 280K with a 2011 3L.

It's never been a problem, Until I jinx myself of course!!

[Tombie]

Last fuel filter change on mine was 80k ago.

New one going in this week (172,000km)

Interestingly, just looked at my last service notes from MR Auto here in Brisbane (who seem pretty clued up) - they recommend every 24k for the fuel filter. More frequent than many are using here - food for thought. It ain't an expensive part.

You are correct, and I have 4 sitting on my shelf.

I use a known clean source for fuel so haven’t worried about it - now I’ve serviced the vehicle fully, and was under there, a new one was fitted.

No change in performance [emoji41]

[101RRS]

The service interval for the 2.7 is 48,000km or 2 years. I assume the 3.0 would be something similar.

I would be guided by that service interval - dirty conditions earlier.

Did mine every 20K Km,or every second service.

While its fine to pick up fuel locally from a place that is known to have good fuel,while travelling its difficult,although we always tried to fill at the larger name brand places,even if it was slightly more expensive.

LR also always seem to use the spin on type fuel filter,so without cutting it up,its difficult to tell how dirty its actually getting.

With a cartridge type its much easier to inspect,although some are a bit more messy to change.

Spoke to the workshop I use , they stated they do them every 50,000km and mine wasn't due so they didn't worry about it, bit strange given I asked for a pre trip inspection due to a 3 month trip coming up and they felt the need to replace a pollen filter again, that seems to happen every service, last one being only 9000km ago although it was nearly 2 years due to the car not being driven for nearly 12 months.
Seems the workshop has mechanics that just go into automatic pilot mode and replace bits that don't need it and just skim over the rest[bawl]

Time to have a good chat with the workshop owner again I think,he wasn't in when I rang them [bigwhistle]

[DazzaTD5]

imho...

I recommend every 10K with the engine oil, oil filter, air filter.
as for changing it too often, what a crock of ****.

But hey, each to their own, it's your HPFP and fuel system.

Mornin Dazza, and so, back on thread, what Km recommendation/s for fuel filter change?

G'day Gavin, I believe he said "every 10000k, along with the other filters".

I go around triple that unless they've been using farm fuel, then it's every 10000

Try to change every 10,000 to 12,000km. My local diesel mechanic recommends every oil change. We were in Brisbane 6 weeks ago, it was 10,000km, bought a new diesel filter along with the rest of the filter's from MR athe uto as it would be a bit over 12,000 when we go home.

Filled with diesel in Redcliffe, from one of teh major fuel outlets, towing a caravan, about 40Km south of Tenterfield, the vehiclevwent into limp home mode. Pulled over turned off an on, anoher 5km same fault . There was a rest area nearby, and checked the fault codes, lower fuel pressure. After serveral more faults we made it to Glenn Innes, where we intending to stay. Did some googling and then mostly likely cause was bad buel, blocked diesl filter. Weather had turned wet so could not change the filter myself, but the local NRMA man foud someone who would change the filter late the next.

With a new filter installed the we did 1,400km over the next 2 days to get home wiht no further issues. Replacement Diesel ordered.

I will not travel without a spare filter and change every oil change. You never know when you will get bad fuel and a blocked filter. It is a low cost item and if you get a fault will driver you to dispair, wife wanted to replace the D3.

So change the filter regularly and carry a spare when travelling. It can be changed on the side of the side of teh road, but is a PIA to do.
