Oil & Fuel Fuel filter placement help

[Flemdog377]

Hey everyone, I just got my tractor home yesterday and noticed a few things that I'd like to fix and some that need to be fixed. I come asking this first question though.

Can anyone share a picture of the mounting location of the fuel filter assembly for a Yanmar 155d? The previous owner deleted it and I'd like to add it back.

From an online manual, perhaps this horrible picture may help:

The 155 FB-1 Fuel bowl same as this Dia. The YM1500 is pretty much the same tractor.

For some reason I can't view your link...

The link from @careyo63 works for me.

A video;

IIRC: there's a long and a short version, but I don't know which fits on a 155D.

All the best,

Peter

Thanks for the help, I noticed I'm missing a bolt too so the sizing helps.

You say its pretty much the same, any thing that might not be interchangeable as I look for parts? Thanks for the help

Go to www.Tractordata.com and look at what they show. Great site to view tractor Info..
look under Yanmar YM1500 YM155 and it will give you the basics on the models.

In that era, Yanmars had two different height filter elements. With a different height fuel bowl for each. The filter assemblies with horizontal output were otherwise identical.

I suggest standardize on the element that was OEM spec for your tractor, even if you have to buy the matching bowl, just to keep future maintenance simple.

BTDT. Didn't realize my larger tractor uses the smaller element, after I had the old element in the trash can and the only replacement I had on hand, was too tall to fit.

On the YTOG we debated in good fun the shorter vs taller fuel filter and bowl. The conclusion was, if there is room, go taller.

To summarize the points for the taller:
- easier to check the bowl for contamination as it's taller. More junk keeps at the bottom while bouncing around on the land.
- shorter means, you change filters much more often at the same price of the taller filter.
- if you venture out into mowing a multi-acre pasture for the afternoon, better have a taller filter setup vs shorter, just in case it clogs up and you have to walk back miles!
- taller filter means more surface area available, thus it takes more time to completely clog.
- taller filter bowl is easier to grab onto with your hand whilst untwisting the locking ring. thus no fuel spilling over your hand like the shorter bowl.
- taller filter can be purchased in many places like auto parts stores, off-road ATV/UTV shops, and motorcycle shops. The shorter filter isn't as popular.

If those diagrams are hard to read, here's what you're looking for.

When I bought the YM240 in 2003, it had a lawn mower filter in place of the proper filter assembly. I went to an importer of VN refurbs and got this assembly off a warranty-return junker.

As predicted by the reputation of the VN refurbs, this had an element and bowl that Yanmar never heard of!

After I bought the proper element and bowl, the filter assembly conformed to Yanmar's manuals.

November 2025 I changed mine.

Here is the tall filter.

And when the bottom is not clear enough to see thru, then it's bad.

Just how nasty was it?

ewwww. and it stunk.

Here is the comparison of the short vs tall bowl.

These filters are the same,

What are the dimensions of the tall filter?

Who made the filter?

and then the bottom of the bowl spring needs to be stainless.

The spring came in the Harbor Freight random universal kit, they work perfectly.

Now this is more like it.

The tall filter is 88mm and the short filter is 69mm in height.

Here is the SHORTY.

Here is TALL

@bmaverick great post on the filter!

All the best, Peter

Interesting. Neither of my Yanmars, tall bowl or short, uses a spring.

The element is forced up onto the nipple when the ring is tightened. There wouldn't be any space for a spring. Later, dropping the bowl leaves the element engaged, to pull off separately.

The original bowls from Yanmar require the spring. The aftermarket bowls do not need a spring, instead they have a circular plastic rib at the bottom of the bowl.

Item-12, the spring.
