Elements are replaced every 20,000 km?
It may depend on the car model, but according to the service data, the fuel filter needs to be changed every 20,000km.
That seems a bit short. Normally, you wouldn’t change it in that span of time.
But I feel that you should do it every 50,000km at the most for a long time. The reason for that is in the fuel tank.
I’ve been shown the inside of a large truck’s fuel tank once, and when I look inside the ano there is quite a bit of debris at the bottom.
It doesn’t seem to say that the fuel at the gas station is definitely clean. So I feel it needs to be replaced for me.
Why is the inside of the fuel tank so dirty?
Whether it is an automobile or a large machine, the inside of the fuel tank is unexpectedly dirty.
There doesn’t seem to be any room for sogginess when you’re refueling at a gas station, but the fact that the inside of the tank is so dirty means that there could be debris and other contaminants in the fuel inside the gas station.
Well, assuming the cloudy black color is just coming back from the deteriorated injection pump, and since the fuel tank is so dirty, of course there’s no chance that the fuel filter won’t be clogged with dirt as well.
I wouldn’t say 20,000km, but 4 years, or even 5 years? You might want to replace it about once in (laughter).
When the fuel filter is clogged.
1: Poor starting
In the morning or in the evening, it is difficult to start the engine. But strangely enough, once it starts, even if you stop the engine for a little while, it starts normally after that.
2 : Acceleration becomes slow.
Does it make it hard to suck fuel and reduce the amount of injection? It seems to accelerate poorly when I step on the accelerator.
3: You’ll hear a knocking sound.
I guess it’s still hard to smoke fuel and the fuel is getting thin. I think it’s always knocking around.
But I think the above symptoms go away nicely when you change the fuel filter.
So I changed the fuel filter.
Both the early and late models of the Delica Space Gear have the same location for the fuel filter.
Back right side facing the hood. A very difficult place to do.
Remove the intercooler, remove the battery, remove the battery base, remove the 2 fuel hoses, remove the 2 12mm bolts and remove the priming pump.
My method may not be very common.
I don’t think there are many people who take off even the battery base.
But I think it’s easier to remove the battery base.
I know you don’t usually remove the priming pump, but if you don’t remove it, my filter wrench won’t fit in it.
There is a thick harness in the back of the filter, so I did not want to mess with it.
So I removed the priming pump and the filter.
Once it’s removed, secure it to a fixed base you made yourself and loosen the filter.
Once you’ve replaced the new filter, fill it with clean diesel fuel before assembling it into the priming pump.
If you don’t put fuel in first, it’s hard to push the priming pump later.
Connect the hose to the filter and put Wes around the bottom of the filter, then loosen the air release bolt and pump the air out of the filter.
Tighten the bolts at the same time as you push.
The next step is to restore the battery. I put a little bit of grease on the 5 bolts that hold the battery base. This base tends to collect water, so the bolts deteriorate quickly. I should have used new bolts, but I didn’t have them available this time, so I just applied grease and that was it.
After changing the fuel filter, start the engine and pump manually.
It’s not over when everything is restored. There is still important work to be done.
The fuel system hoses were removed and the filters were replaced, so even though the air was removed by the feed pump, there may be air that hasn’t gone out yet.
So I’ll start the engine and pump the feed pump about 50 times.
The reason why you need to start the engine is because if you don’t start the engine, the injection pump will be closed and no fuel will flow. If you run the engine, the injection pump is open and the excess fuel with air mixture will flow through the return hose and into the tank.
If you’ve done that, it’s perfect!
Impressions after changing the fuel filter
Yeah, I’m faster. Maybe it’s the placebo effect, but really!
Maybe it’s swishing fuel. I think the engine is quieter too. I’m not sure about the fuel economy, but engine wise it sounds healthy.
The engine runs perfectly!
Then there’s the first morning engine start and the evening engine start.
If you can clear these areas as well, it would be a good part to change the fuel filter regularly.
It’s so effective that you can feel it, so it’s better to do it than not.
Where to buy a fuel filter?
I think I’m fine with the cheap stuff online. If it’s something that works well, I think the stock one is good, but it’s just for filtering fuel. If you buy online, you can get the same filter as the stock one for about half the price.
By the way, there are filters that are even cheaper than the genuine equivalent. Is it safe to use such a thing? But…it seems to be okay. I’m using it too.
The oil filter is the same, but it’s “just for filtering”, so you don’t have to pursue the quality so much.
So far, no problems.
Replace the hose every once in a while.
I’ve had problems with the engine not starting before.
The cause of the problem is that the replacement of the fuel element has loosened the rubber hose plug that connects to the priming pump, which has deteriorated and lost its elasticity.
The air must have gotten in through there.
I’m thinking. Well, in a strange way, the trouble that might not have happened if I hadn’t replaced the fuel element…
So if you’re thinking of replacing the fuel element, you should replace the rubber hose in the vicinity with it, even if it’s a hassle.
