Fuel filter bowl with drain

[mikeh19d]

I have a 2018 LS XG3025H and for some reason or another I'm getting water in my diesel fuel. I have changed the filter on the bulk tank but it seems water is still getting into the tank on the tractor. So what I'm looking for is a fuel filter bowl with a drain in the bottom. This way I can twist open a petcock and drain the water before starting. Does anyone know where I might get one? The fuel filter assembly number is 40207336. It seems this fuel filter assembly is used by a number of different manufacturers so I was hoping the part I need is out there. Thanks.

Steiner tractor parts website shows several 'sediment bowls' that ought to help you with this water problem. I searched for 'fuel filter bowl' and got several.

Think I'd install a Racor style fuel polishing unit between the fuel tank and the engine fuel system. The Racor style fuel polishing systems remove 99% of the water and other junk down to 30 microns and they have a clear bowl on the bottom that can be drained as well. Run them on both of my Kubota's. You can even get bowl heaters for them.

Since I installed mine, I've yet to change a spin on fuel filter or drain the clear sediment bowl.

If you open the bowl, won't you likely need to bleed the injectors?

I suppose there could be a design that let the water out but no air in, but it might be finicky.

I was thinking that too, but does Racor make a small version filter setup that is easier to mount on a small tractor?

Sure do. I actually bought a pair of Conus Racor style fuel polishing units and refitted them with Racor aqua block 30 micron pass spin on filters (Racor Store & Amazon). The entire units measure about 5.5" long and 4" in diameter and the filter base has two through holes in it to mount to the tractor (actually a marine diesel unit). Put mine on the FEL loader upright. Very compact and the bases come with 2 inlet and 2 outlet threaded holes so as well as the barbed fittings and blanking plugs so there are many different combination to install them at. You run the fuel tank feed to the filter inlet and the outlet goes to the engine / primary filter in front of the fuel pump (lift pump) so the fuel is pulled through the unit. Very simple install. I like the clear bowl because all I have to do is look to see how much is collected and crack the bleeder valve on the bowl to drain it off.

If I remember correctly, the Conus filter bosses (and they came with a generic Racor filter were 28 bucks each and the genuine Racor 30 micron pass Aqua Block filters were 30 bucks each from the Racor store.

All the brands of polishing filters, all have the same threaded base so you can interchange spin on filters, don't matter what brand it is. I wanted genuine Racor so that is what I bought.

You don't have to pony up the big bucks for a genuine Racor filter and base as all the generic bases (made across the pond) will accept a genuine Racor spin on filter. Mine are very compact. Primarily made for marine use but diesel is diesel, boat, tractor or on road motor vehicle. As an aside, I have one on my class 8 road tractor too, came with the truck as an option when I bought it new.

I never have. The filter isn't even close to the injectors and the inlet and outlet is on top, the drain is on the bottom.

Thanks for that info. I didn't know that about that about the adaptability. I laugh at the fact that they have the reputation as a marine filter, but they are very good.

I think you might look at the Racor 120A.
Racor at Zorro

It is available with 2, 10, and 20 micron filters. Flow rate I think is 15 gallon per hour. I read an article that suggested 10 micron filters. I would call Racor and discuss it with them. The 120A is supposed to be used on the vacuum side of the pump, making it good for right after the tractor tank. I also saw a thread where one was installed on a Kubota B Series (I think) tractor.

I think the racor is the best way to insure there is no water in your fuel just before it it is used.

I have an L4701. The water separator is not much comfort. I have been wanting to see about installing Racor on my tractor also.

Marine diesels always have a water issue so it's imperative they have a polishing unit between the fuel tanks and the engines. Even on Amazon and elsewhere they call them out as a marine accessory.

The new Kubota tractors that are T4 with common rail HP, ECM controlled injection are coming through with polishing units from the factory now. Though I have not seen one personally, I'll bet the base will accept a genuine Racor Aqua Block filter as all the bases have the same mounting threads and sealing boss diameter.

You can actually purchase a genuine Racor water block spin on filter element with a 5 micron pass rate but I believe that is a bit overkill. The OEM Kubota spin on fuel filters have an 80 micron pass rate, so 30 should be just peachy. 30 is kind of the standard because the lower the pass rate, the lower the overall GPM throughput is not that tractors need gallons per minute throughput in the first place.

When you open the bowl drain you close it before any air gets sucked in. real simple but takes some attention on your part. I drain mine with the engine off and then start it and allow the lift pump to pull the fuel into the unit. Over the last year, I think I drained it maybe twice. The bowls hold a fair amount.

Again, why purchase the genuine Racor filter base for big bucks when the offshore filter base costs about 1/10th of the Racor base and is exactly the same. Not only water but any debris that might be in the fuel. It gets everything and the debris is also dropped into the bowl for removal.

The flow rate drops as the micron pass rate drops as well and like I said, 30 is fine compared to the 80 micron pass rate the OEM Kubota filter is rated at.

Far as I'm concerned they would be a good addition to any tractor, not just Kubota and I did a thread in the Kubota sub forums

I do renew my spin on Racor filter every year as a maintenance item. The clear bowl is removable and reusable, the only thing you might want to replace is the sealing 'o' ring but so far I have not.
