Yes the 4M40 has a combo filter, ie it has a full flow and bypass in one filter, also very common in the states.
example of course yours is not this big nore will it have the same media in it but it will be similar. You have two elements, a full flow section then a bypass section in one filter. As stated at the start of the thread bypass filtration is a mainstay for diesel engines.
Bypass / combo filter.

* Combo style filter
As far as fuel filters that's pretty easy, you want 10 micron or better filtration. 15 micron is most OEM standards. You can get higher efficiency ones that go all the way down to 2 microns which will double your fuel systems life. You can't really add a 2 micron filter to a old school diesel because the lift pump might have issues flowing. New common rail is no issue you can add one in line with the stock pump.
You want less than 10 microns for a really good filter, Donaldson, Baldwin, Fleetguard and WIX all have these down to 2 microns.
On a diesel your fuel filter is just as important as the oil, Go cheap and you'll have problems.
Fuel filters are close to the oil filters in design as far as the filter media goes.
Diesel Engines generally use one of two types of lube filtration systems:
A Full Flow system
A Bypass or Part Flow system
A Full Flow system works the way it sounds. The entire flow of the fluid (oil, fuel, etc.) passes through the filter on its way to the engine.
In lube systems, the full flow filter is by necessity an open filter.
The full flow filter cannot restrict oil flow used to control larger particles, the full flow filter cleans all of the oil going to the engine.
A bypass or part flow system has a different flow path than a full flow
In a bypass system, a small amount of flow, usually controlled by an orifice, is taken from the main flow stream that oil is passed through a filter and then returns to the sump.
Due to the lower flow of a bypass system, a bypass filter can remove smaller particles.
Basic filter parts.
Filter Bypass Valve allows unfiltered oil to flow around (bypass) the filter. Not to be confused with a bypass filter Every lube system has a bypass valve.
May be part of the filter or part of the engine Antidrainback Valve Used for inverted applications maintains a head of oil to prevent dry starts. Used in conjunction with a standpipe.

Useless ang paggamit ng modified filter na yan dahil hindi marami ang amount ng motor oil na nasa loob ng makina ng mga light duty diesel engines ng mga sasakyan natin.Hindi pwedeng patagalin ng mahabang panahon ang change oil di gaya sa makina ng mga malalaking trucks/buses.Ang ratio ng dami ng langis sa displacement ng makina will decide the size of an oil filter & change oil interval depending on what type of oil we use.
Makes sure they are real Baldwin filters plenty of fakes in that part of the world.
Biggest thing to look for is.
Country of Origin - Baldwin manufactured filters are marked with the country of origin. Baldwin has manufacturing plants in the United States, the United Kingdom, Mexico, South Africa, Morroco and China. If it does not have this it's a fake just makes sure you getting what you paid for.
Other stuff.
Color
The color of a Baldwin spin-on filter may not be correct on a counterfeit filter. It may be close, but just not right.
Graphics
Graphics on the filters, including the logo, may be missing or incorrect. In the photo to the left, the counterfeit filter has 2 I's in Baldwin.
Components
A counterfeit filter may look right upon first glance, but upon closer examination, you may find major differences. Some places to look include:
Dimensions - The dimensions of the filter may not be the same as a genuine Baldwin filter.
Baseplate - The baseplate may look different or be made from a different material than that used by Baldwin.
Media Packs - Counterfeit media packs often have an obviously lower pleat count than Baldwin. In addition, the pleats may be deformed.
Gaskets - Both internal and external gaskets may look different or be made from a different material than that used by Baldwin

Sir, I am the owner of Devilsown Alcohol injection, the filter thing is more of a hobby, I am also still active duty U.S Navy until I retire next year. But I would be happy to provide you with the filter number for that engine.
I do have a bunch of filters I will ship when I do retire late next year but that's a long time away, Like late June of Next year when I move to the Philippines for good.
You can use a Fleetguard LF3830 or LF3564 or Baldwin BD28 WIX is also a good brand ant it's a 51067
BPV Setting 100 kPa (14.5 PSI)
Largest OD 110 mm (4.331 in)
Overall Height 138 mm (5.433 in)
Thread Size M26 X 1.5-6H INT
You can find these fairly easy especially the WIX but they are not cheap. I'll pick up a few cases between now and next year I'm sure. These are just hard to find nothing really uses this thread size.
Do a search and you will find plenty around most under 20USD. If you have someone visiting the states have them pick you up a few. Even I don't have any, and I got like 500 filters in my storage.

Baldwin shop is Volmax - I don't have their number right now. I'll give it out on Monday. The shop is on s padilla in Manila.
Wix filters on the other hand is sold Superior Motors 3741737. It is near Quezon Ave.
from what I have researched these are the two consistent high quality filters even in the US
OT: hi dvldoc. I have a PM for you regarding alcohol injection that I got from you years ago.
Wix is a excellent brand, actually one of the better over the counter filters. Just make sure it's the real deal.
WIX Box should look like this. and if it does not say WIX Corporation, Gastonia N. C. made in USA on the back it's not the real deal.
The other countries of production will be these. If no country of origin then it's not the real deal.
Mexico
Ukraine
Venezuela
Brazil
Poland
If they come in a plain white box with a Wix label stuck on, are white in color and they come in shrink warp plastic. They have the Wix part number stenciled in blue on the filter it's not the real deal.
Two style boxes
As you can see they are high quality filter, I got a bunch myself, If I see them on sale I pick them up.
[SIZE="4"]So...saan ba nakakabili ng dual filtration system dito sa Manila?
Tsaka pwede kayang maglagay ng secondary filter para sa diesel, yung tipong
maglalagay muna ako filter na pang gas na nakaseries sa diesel fuel filter..?[/SIZE]
That's a pretty low price for a imported Baldwin, If it's a real on then it's a good deal.
Let us know if you get one and if it's the real deal. It should be a Baldwin BD28.

sir Dvldoc, quick question lang sir..
is the Baldwin BD28 suitable for both 4m41 and the 4d56?
because the OEM mitsu filters for both 4m41 and 4d56 not only has a difference in part number but also in size...the 4m41 being bigger....
does it mean that the baldwin bd28 has a universal fit?![]()

i think the cheapest quality filter will be bosch..
sir locoroco, try to call Volmax. im not sure if 4m40 and 4m41 has the same filter, but when i inquired regarding 4m40, wala daw.
bosch lang meron. c/o warren auto supply
The 4M41(OEM ME013307) filter would be the BD7028 also a combo filter and dual flow.

So to answer your question yes you can use it. Here's the thing with oil filters you can go bigger or smaller as long as you have space 1 or 2 inches will not make a bit of difference in most vehicles. It all depends on the space you have to work with different manufactures have different sizes for the same filter.
The portant part to get right is the thread size, filter type, and by-pass valve.
The BD28 is used for all those engines. The BD28 is physically a little smaller by very little.
