Racor filter on a bx24

[Hvytrkmech]

Wow all kinds of conjecture in this thread.

In a fuel supply system it is ideal to have the filters/water separating devices on the push side of delivery, NOT the suction side. Once you break open a fuel system to service it you should plan on priming it, you do FAR more damage to the fuel system by air bounding the injection pump then you do with poor fuel or water in your fuel.

The 2 micron rating is all hear say, there are ABSOLUTELY NO sae testing and verification procedures in place to test below 4 microns, so if you are buying a filter rated at 2 microns It does not meet sae standards. Now this does not mean that the filter is not an 2 micron filter, what it means it that you are at the mercy of the manufacturers word that their filter does what it says. Try and contact the manufacturer and see if they provide you with any proprietary information on their 2 micron filters. What I believe you will get is a response stating that they have changed the methods they use to apply a rating to their products.

Furthermore, water emulsification/stripping, and 2 micron filtration is essential to HEUI and HPCR fuel systems. The mechanical direct injection system we have in our tractors would pass debris in the 15-25 micron range without ever even knowing it was there. The only benefit you will receive by adding these Racor systems is the water separating, and even that is superficial.

Save you money time and headaches, just buy your fuel from a reputable location and treat it your self at the time of delivery or pick up so it is well blended.

Air in diesel engines fuel delivery system is nothing but a compressed gas that will be released when it enters the combustion system and used as fuel as well.

With indirect injection fuel systems it is not an issue as the indirect injection pumps are lubricated by both fuel in the upper half and splash fed from an oil reservior in the lower half of the injection pump.

Direct injection pumos are at the mercy of the fuell delivery system and if starved will sustain damage.


I have used the 2 micron filters in underground mining service and had roof bolters stop dead in diesel service with suction side filtration so thats a given in my case and why I am so fond of the model 500 filters with the turbines and settling bowls.


The fuel used in japan Is filtered to a much higher degree of filtration for particulates and water at the dispensing point and thats why they have stuck with the smaller filters.



Racor has always stated that their fuel filtering systems can tolerate 30 PSI maximum but the preferred method is on the suction side of the injection pump for diesel engines.

The water separation benefits of a turbine fuel filter are that it removes most if not all the residual water in the diesel fuel with the settling bowl and the cartridge filter.


They also have a number of studies to support thier line of fuel filtration systems for diesel fuel and gasoline.

I will add them here when I have a minute.

Most of the Racor and other fuel treatment system I have, and currently deal with are not on the suction side. However, there are filtering/processing systems that are on the suction side of some fuel systems, so with that being said I agree with you. My statements are directed solely in regards to implementing these types of systems onto these home style tractors. But then and again I am not, nor will I ever be a Kubota technician.

As a side note,

What happens to a fuel delivery system that is set up on the suction side, then all of a sudden it has a small failure in lets say an o-ring?

No information in either of the attachments to verify either way.

Parker calls for this filter to be installed on the suction side. Here is the PDF instructions for this filter which states: 120A and 120B fuel filter/water separators are designed to be installed on the suction side of the fuel system with maximum flow capacities of 15 and 20 gallons per hour (GPH) respectively.

Funny it states that it can be used in either manner with the only exception being on the pressure side. Pumps emulsify water hindering filter performance.

Makes me wonder what type of media they use? Smoke in mirrors at this point. I do not deal with these types of low flow systems so have virtually no experience with them specifically.

Cool little filter assembly, looks perfect for what you guys want to use it for.

Bets of luck with them, and Thank You for the clarification.

The Racor "Proprietary" "Aquablock" filter repels water and forces it to colalesce and settle against the drain bowl.:thumbsup:

Dropped the x-24 off at the Dr's today to get some leaks the hydro creep and a cracked hood fixed. The good thing is it is under warranty the ad thing is that it's a 100mi round trip for me I decided to wait before I install the 120as filter assy until after the trip to the dealer. It looks like if I relocate the stock plastic filter that is located just before the injector pump i can fit the racor unit in there under the hood. The only thing is that to get the suction end of the tank I have to run a big loop from the underside Pre-fuel pump to the racor under the hood and back o the fuel pump. I will look closer after i get her back but I think with some wire loom zip ties and a few fittings I can get a god factory looking install. (pics to come for sure) Thanks all for such imput I think this thread may benefit more than just me.


take care

Hello John,

No worries about the distance as long as you have good hose that is reinforced it will be fine. I would be worth it to buy some of the Racor hose if you can.

The Racor dealers will ship things like the filters and parts so hose should not be an issue if you want to buy the right hose.

Still wondering why you keep pimping this Racor and what data says it is needed.

I would think that "pimping" is a rather strong term. An opinion question was asked and numerous posts were given. I think it is a question of some people chose to be more cautious and maintain their equipment over and above sometimes what is needed. For me personally This machine was a HUGE purchase and I intend to keep it as long as I can keep it going, for the cost of a $50 filter unit and some goodyear hose and a few fittings I want that added protection. If members here have a strong opinion one way or another good for them for taking the time pro or con to voice that opinion But as far as "pimping" a product that is a little harsh.
