Buying Advice Tier V emission standards soon for new diesel engine tractors?

Yeah… it’s kinda interesting to bounce around the concept in your head, that all the evidence of wrongdoing uses nationwide statistics of all the vesicles sold , and how much damage to people they did, yet, all the 1.675 Billion dollars , plus some other assorted millions go to one, single state.

I guess it can be used to help fund that state’s new “free” healthcare for illegal immigrants program

The biggest improvement in diesel pollution, IMO, was a few years ago, when they removed almost all the sulfur from the fuel.
Before they did that, the exhaust gave me headaches, but now, no issues. Unfortunately, without the sulfur, our engines will wear more rapidly. I add 3oz of 2cycle oil to my fuel for my Kubota to replace the lubrication that was lost when the fuel was changed.

Often when there are new laws enacted, there is financial gain for a senator involved.

I've had zero issues with the ULSD off road diesel fuel in either of my pre emissions (T4 interim) Kubota M9's at all and other than the biocide and in the cold winter some PS winter additive, I've had no issues what so ever and both have some serious hours on them, 6000+ on the cab unit and 4500+ on the open station and it's 90% working hard as well.

Both run excellent and both have just been in the Kubota shop for overhead adjustments and both have gotten a clean bill of health.

I retired from heavy duty trucking driving a company truck and trailer with big Cats and when they went to ULSD, of course the fleet did as well and there was never an issue with any of those engines either. The company never added any additive to their fuel tanks except for in the winter again and that was PS winter additive and that was it.

From that experience, I don't buy into the philosophy that ULSD causes issues with mechanical injection pumps or injector pintles because I've never seen it happen.

Have no idea about the newer HP common rail engines, because I don't own any and don't want one anyway.

Probably the best thing I did was add Racor fuel polishing units to both of mine and all the heavy duty trucks I drove before I retired had them installed as well. The Racor units positively remove 100% of any water and debris in the fuel and really negate any filter changes or draining the 'sediment' bowls. I don't fiddle with them at all now.

Again, I look at 99% of the 'elixir's' as nothing more than advertising hype designed to empty your wallet faster.

Several years ago, I researched this issue and I found it is true that when sulfur is removed, lubricity is also removed with it.
At that point is up to the fuel company to add the necessary lubricant package to replace what was removed. I do not trust the fuel companies to always do what they should, especially in the last several years. I will try to find the various articles I had and review them. While I don't condone using additives because a paid actor promotes it, I know that there can be benefits from certain things added to fuel or oil. In fact, all oil and fuel has additives to alter its normal behavior.

I've heard that adding Red ATF works but like I said, I've never done that. I guess it all distills down to whatever floats your boat. Myself, I prefer to use as little ancillary stuff as possible and so far at least, I've had zero fuel issues with either of mine and when my dealer ran the overheads, he also pulled the injectors and spray and pressure tested them and all was good. Maybe my fuel supplier is adding something, I've never asked but I get my fuel delivered by the same supplier and have for years now. So far, no issues.

I think you have a reputable fuel supplier, so you may never have an issue, which is great for you. I have to get my diesel from UDF so I am skeptical of the quality. Their main product is ice cream, so I don't expect high quality fuel. I am unfamiliar with Racor so I want to check them out. Sounds like a good investment. Thanks for the info.

Couple of us have them on here. I went with the China clone 'Racor' base instead of the super expensive original RACOR, but the clone takes the Racor filter elements anyway. The Chinese clone is about 1/5th the cost of the Racor body. I bought a pair of IFJF bodies from the Amazon website. I have not changed the spin on engine mounted fuel filters or drained the sediment bowl since installing them as there is nothing in the sediment bowl at all so I also presume the spin on engine mount filter is also clean.

Nice thing about them is all you have to do is look in the clear bottom bowl to see what has been deposited in it and open the drain valve on the bowl and evacuate any debris or accumulated water. Mounted both mine on the FEL stationary upright and they aren't overly large either. Just so long as they are out of 'harm's' way, it's all good and simple hookup as well. Cut the fuel line from the fuel tank and fasten it to the supplied with the housing, barbed nipple and the other end goes on the other nipple. Hardest part for me was mounting the units. I used my Mag drill to drill and tap the mounting holes and I used stainless socket head capscrews to mount them. The bodies are supplied with a pair of barbed fittings and 2 blanking plugs as the bodies have a pair of inlet holes and a pair of outlet holes and the come with a port on the top so when I change the filters, I fill the now empty unit with clean diesel through the fill port on the top. That way I don't have to fiddle around with bleeding the injection system at all. Real simple install and candidly, I only change out the spin on filters every spring and not sure I even need to do that actually. I may add a pair of pressure gages in the blanking holes to monitor pressure drop at some point.

I was looking at the new common rail Kubota tractors the other day and I see Kubota has added fuel polishing filters to them. However, they are solid spin on filters with no clear bowls on the bottom and I checked with Kubota to see what micron rating they are and found out they are 10 micron. You can get the Racor elements at 5 micron. The finer pass the better far as I'm concerned.

Sounds like a real winner. I would like to install one on our 300 gal diesel tank at work. I guess it should work on that too?

One thing I did add long ago was a Kubota mesh fuel filler insert and I presume they will fit about every brand of filler neck as they come with various sized washers for fitment and they are pretty cheap as well, think I paid 10 bucks each for them. That way I can mitigate any junk that may fall into the filler when I'm fueling my tractors. Lots of times I'm fueling a dirty chaff covered tractor and that chaff has a bad habit of falling in when I'm fueling. I always figure, the more 'filtration' you have, the less issues you will have in the end and I've read on here and elsewhere about 'junk in the fuel tank' plugging up the fuel hoses. I don't need or want that to occur.

Absolutely correct. My old Kubota came with a very fine strainer. It's so fine that you have to put fuel in very slow.

I still remember 50 yrs ago I was baling hay for the first time with an old IH. When I removed the gas cap it said in bold letters,"Buy Clean Fuel-Keep It Clean". Since then I try to keep it clean.

Absolutely it will. My bulk tank is 500 gallons btw and like Hay Dude, it always hurts to fill it, especially today with inflated fuel prices.

Lots of people run the 'Water Block' filters on their bulk tanks. Far as I'm concerned the Racor units are 10 times better. Like I said, the clone 'Racor' bases are a lot cheaper and the exact copy of the Racor unit as well. The Chinese are real good at copying stuff today. While I don't profess buying Chinese stuff and normally I don't, when you compare the costs of the Racor body to the clone body (which is an exact copy), in my view, the Chinese clone wins out, especially when they perfectly accept the Racor eleements.

Just keep in mind that they are ONLY for diesel fuel and not gasoline. You'll see bad reviews on Amazon concerning them but the idiots on there tried and failed to use them for gasoline. You put gas in one, all it does is destroy the plastic bottom bowl almost immediately and I noted that aspect in the reviews on their site. They plainly note 'diesel only' but I guess idiots cannot read but they sure can whine.

Marine diesel powered ships, both commercial and pleasure have used polishing filters for years to insure their fuel supply is clean and free from any water or debris. Marine diesels are just like your tractor, they are diesel powered. Of course large commercial marine diesels are burning bunker fuel so it has to be heated prior to filtering anyway and the Racor's on marine diesels are huge. You won't find any marine diesel without fuel polishing filters. SOP with them.

I actually have one on my Class 8 diesel truck as well, it was an option when I bought it.
