New Holland Tractor Fuel Filter Issues

swax · Nov 23, 2017

I have a 2000 TL-70 with 2000 hours. It breaks down every 20 to 30 hours. First looses power and black smoke. Than stalls.
It took years to realize filters were clogged so quick.
A)replaced all fuel lines.
B) added fuel treated, although own numerous other diesel equipment that have no issues.
C) replaced lift pump with electric pusher pump 18psi
E) removed plastic fuel tank and checked for obstructions and dirt. Very clean, but recleaned.
E) sent injector pump out for rebuild. Re builder found no problem and stated, pump is as it should be.
F) Tractor has a loader. Very hard to change filters. I relocated with larger,low priced Fram fuel filters, and located in a simple area to change. To my surprise, they only lasted 25-hours.
G) put fuel pressure gauge after filters. Brand new filters have 8-psig before injector pump. After 10 hours drops to 3-psig.
H) very little fuel goes back to tank.
I) It was impossible to bleed bottom of filters prior to re-locating. I can do it now, but so far have not. I did not think that would cause the filters to clog that quick ?
Thanks in Advance.
Runs excellent every time I change the filters. With the electric fuel pump ! I leave the key on until see the fuel pressure gauge at max. (filled filters before installed). I still need to spray starting fluid , but will restart quickly.

Might want to consider where your getting your fuel from.
Also some filter have different micron ratings, the lower the micron rating the finer it filters, but it also stops up faster.
I'm not a big fan of Fram filters.

I don't understand your first line. Are you saying it looses power and looses black smoke? It should not be blowing black smoke when running. Now if you mean it looses power then
starts to blow black smoke that does not seem like it is lacking fuel. I wonder if you don't have something else going on.

Check what filters you are using. A very fine filter for a
common rail diesel acts like you mention. My truck was the
year they decided one small fine filter was plenty. Fuel that
goes through all the tractors fine plugged that filter in a few
hours. It?s been replaced 4 times since I filled the tank with
that fuel and a filter will now last maybe 3000 miles.

I bought a big coarse pre-filter kit with spin on to stick ahead
of it, hope to finally get a year out of a filter.

black smoke, might want to check your air filter and intake

Are you fueling other tractors with this fuel? Is the tank
venting properly? Do you have a line collapsed?

Are you using the correct NH filters? If the filters are "clogging" I would cut one apart and see what they are clogging
with.

Had same thing with a Kubota
skidloader,ended up removing the fuel tank
and flushing several times. I think that
when someone borrowed it they put old fuel
in it and the algae keep plugging the
filter

I am using off road diesel with antigel agent added.

When its running correctly, very little noticeable black smoke.
This is hilly land. I notice the problem immediately, because I need to downshift to clime hills and black smoke becomes very noticeable. I was using the spec NH filters. Cost for two, are over $80.00. So I changed to the same micron size in a Fram, for $5.00 each. They are twice the size of the NH and was hoping, can go twice the hours, but no, about the same.

What is the micron rating for the filters your using,
Is it compatible with the micron rating of the filters on your other equipment.
As others have said ,cut a filter apart and see whats in there causing it to plug.

Sounds like you have algae in the fueltank. Better get a good biocide and add it to the fuel and kill it off.

JD Seller · Nov 23, 2017

I ran into a tractor like that once. It had the fuel tank loaded with algae and crud. I pulled the fuel tank off and flushed it out with muriatic acid. I then put some ethanol in it to absorb any water left and dumped that out. I filled it with fresh ROAD fuel with a fuel treatment. I then installed a large in line filter in the line going to the original fuel filter. Now the tractor will go several hundred hours between filter changes.

I think the key was killing everything with the muriatic acid solution. I put one gallon in five gallons of water or 20% solution.

JD Seller · Nov 23, 2017

Also dump the Fram filters. I have found them to be finer than the spec.

WOW, you must have moisture in your fuel, and moisture = fuel = algae.

Clean up your fuel handing procedures to keep moisture out, and treat with biocide.

Like Bob said, you have a moisture and algae problem, if it's coming from a on farm storage tank you better get a handle on it before you have problems with all of your equipment.
Other wise clean the tank on that tractor, kill the algae and figure out where the moisture is coming from.

Are you running bio-fuel, I've heard it has more trouble with algae.

I have a outdoor 275 outdoor oil tank in good repair. I drained a gallon out of bottom in a clear bottle. See no water. Added same product as in the post before yours shows, directly into storage tank.
Added a very expensive algee killer. Small blue colored bottle ($30.00) directly into tractor tank. I"ll admit , the fuel is two years old. Not using equipment like I use to. I did not know what algee looked like. The fuel , foams, looks, red and clear, if I pump it in a clear glass jar. Have a coarse filter at pump.
How can I control, the lack of demand for fuel ? I cut 80 acres of pasture a year and let it lay. I have the other equipment, because, I built a 4 acre pond, that has been done, for two years. Thanks

You have/had the algae in the fuel. It maybe dead but the remains are plugging up your filters.

Take some of your fuel and pour it through an old tee shirt. You can see the small algae in the shirt.

For your low fuel usage I would stop keeping fuel on hand IF you can buy it locally. I can buy off road fuel at the local truck stop/gas station.

Despite treating the fuel, I never suspected fuel as the problem. My backhoe, dozer, and Mack dump truck ran great. I was told by a diesel mechanic, who looked at the New Holland, their are algae problems with plastic fuel tanks. Being I keep it indoors, he thought it would be okay. I never keep any old filters to show him. I did not know, what to make of the filters, but thought it odd they looked that dirty for 20-30 hours. I guess it will take some time for things to clear up. I would say I use about 100 gallons a year. If I run the tank dry, drain it, and buy 100 Gallons will the problem persist? I am in Northeastern Pa, and the Napa store said algae problem was widespread. So I treated for it. I was unaware, dead algae is a problem also. I want to thank everyone for their input. This has been a 4-year problem and a lot of expense and lost time. Im glad I took the pic, and finally went to a knowledgeable site to get help. Thanks again.

Did you buy it new or used? My NH had a small in-line filter, about as big as your closed fist, installed between the cab & the engine where you could never look for it unless you put it there. And it was loaded with algae. Replaced that filter only & its worked great for 8 years. Factory books don't show it so someone must've installed it thinking more is better.

I bought it used maybe 10 years ago. It has a loader frame that completely covers the filters. Dealer changed all filters before I bought it. Said to change filters around 300 hours (I think). Probably had about 100 hours on it, before it stopped. Yep ! after I located the filters, they were a challenge to get off and blocked solid. However in my case, the time to change the filters keep shortening. I completely changed the fuel system. If I did not replace the mechanical fuel pump with an electric one ! I would need to bleed injectors every time it quite over the last 4 years. I think all new tractors have electric pumps. Now that I know what the problem is I'll figure out how to fix it.
My fist plan is to use a tractor fuel filter on the tank fuel pump. That may clear up my last 80 gallons in the tank. I have a bunch of the Fram filters, so I will use them up.

Dune Country · Nov 24, 2017

OK, problem solved, can anyone explain the black smoke?
sucking oil past the pump seals? or out of the basement?

Oliver 500 Wa · Nov 24, 2017

Large diesel powered boats often get algae or other microbial contamination in their tanks. If it gets too severe for the filtration system to deal with then the fuel and tanks need to be cleaned. There are companies that do "fuel polishing" on these boats to clear up the problem.

https://en.wikipedia.org/wiki/Fuel_polishing

Possibly there is a company offering that type service near enough to you.that you could hire to clean your tank(s) and fuel.

I refuse to use anything other than OEM filters.

I have had this happen when I had a fuel flow obstruction. It made no sense to me, but talking to an injection expert I learned that Black smoke when running out of fuel is normal.

Destroked 450 · Nov 24, 2017

I've had the same thing happen to some of my tractors, run them out of fuel or plug a filter and as their smothering out they will blow black smoke. Makes you think something else is wrong, but put in some fuel or change filters and it run just fine after you get it bleed out.

Yes ! I would say absolutely. The very first sign was throttle needed to be increased. At the same point in time, noticeable increase of dark colored exhaust. It was time to head the tractor back to the barn. Sometimes, I made it, sometimes not. Years back, I disregarded the filters, because they had such few hours on them, they could not possibly be the problem. But in order the get the tractor to run, they had to be changed. In the last year ! Black smoke = fuel filter change. Really cannot be anything else, because it runs, perfect with new filters.
