BEST way to bleed diesel fuel system (step-by-step) 

🥰 I just helped my hubby start his tractor. He just thought he had let all the air out, and I coerced him into proving it to me, lol. I didn't let him tighten that nut til I saw a steady stream of leaking diesel. Viola !! Lol! He knew what to do; he just was being impatient.😊

Thank you lots. The tractor was on a slope tank end down and it would not take. Towed it to flat ground and your tip worked a treat. Thanks again.

I ran out of fuel and wanted to add to this video. If you locate the fuel hose that is dumping back into the fuel tank, take that line loose from fuel tank and attatch to an electric fuel pump, hook electric fuel pump up to external battery source then you will start blowing air and fuel out of that fuel pump, it took me 2 cranks while hand pumping the manual fuel pump above fuel rail. Worked like a charm and i was on this for 3 hrs before i hooked up electric fuel pump bleeding lines. All this after you fuel back up of course.

Lifesaver, been trying to start my Toyota Lucida for an hour and couldn't figure out what was wrong. She's purring again now

This is so useful !!! I have a 1950 fahr diesel tractor and this year for some reason it had lots of problems like that with air in the system

Thanks for that short and clear explination

My friend, you just helped me out a great deal. I have the same engine, bled the first two points, sat there looking at those injector connections and dreaded trying to get to them. I had no idea the battery folded back like that! It's my Dad's old Ford 420, so I'm learning about it more and more. Thank you!

this was really clearly and simply explained, thanks for uploading so I don't have to ask my father!

Thanks alot your video got me back at work alot faster and that keeps the boss happy!

I gotta thank you , i let my machine out of diesel last week and couldn't bleed it , i followed your instructions and hey presto it cracked up straight away. It needed diesel to get it above the filter.

Thanks so much. Didn’t run out but ran into some bad fuel so this helped me a ton.

Thanks mate, I just did this on my Valmet 502 tractor and it worked aplomb. Thank you.

Great short video. Uhhh, changed fuel filter and got air in the line. My bad. But your video helped me out. Thanks.

Good video, never realized the fuel level in the tank had to be above the filter, great tip. Also pressurizing the lines, didn't know. I've had my 235 since 1977, only time it's never failed to start was due to a battery, terminals, or I ran it out of diesle. thanks

Thank you, you saved my day! in Vanuatu, south pacific islands

Thanks.. exactly what I was looking for... thumbs up

Very well explained. Easy to forget to fill fuel tank higher than injectors OR to crack the bleeding bolts on top of fuel filters (which you prefilled with diesel fuel as well). Thanks.

excellent video. thanks for sharing

Worked like a charm thank you

A lot of newer diesels have a lift pump that will bring the fuel up to the filter so you wont have to fill it above the filter. Also a lot have a bleeder valve for the injector pump located in the front of the injector but is still a good idea to crack the lines since air will still be trapped in the lines

Good man! Nice tractor, just like my dad’s

That engine sounds great

i love you sir you saved my day ❤ awsm video

Nice tip - make sure the fuel level in the tank is higher than the bleed screw or you'll have a siphon.

thanks for the video.

Thanks. I run a pony motor on my trailer and been dealing with a hard start. I'm gonna give this a try

Nice job bro

Thank you sir for the no bullshit video!

thank you for being concise sir and not taking 20 minutes to tell us what can be said in 3-4 minutes. Very helpful to a man with an empty fuel tank on his boat ( me).😮🤔😄🫡

Very good video !! Easy to follow

Turn the nuts on the fuel injectors to bleed the air out, keep it open and crank the engine until u see the fuel fly out the nut even 3 injectors tight it up and done. I usually do it, dont have to open crank and tight it up so many time

good vid

Thank you!

Excellent job!

Thanks bro..

THANK you so much

Best video for us airheads with tractors lol

Thanks man

I appreciate it! 👍🏻

Love you error code guy

thank you sire :)

I'm planning on changing my primary and secondary fuel filter/separators on my 8.2L Turbo Diesel. Do I need to prime the fuel system afterwards or should it be ok?

Thank you

Thanks

Omgggggggggg THAAAAAANK UUUUUUUUUUUUUUU !!!!!!!!!!!!

thank you

Thank You solved my problem

Spot on advice thankyou. Sorted my Ford 4000 in minutes!!

Holy crap it worked!!!

Im going to try iy now

i have a cold start problem on my 2003 d4d corolla. If i press the fuel primer button, it starts much better. What is your diagnoses of the cold start problem eg fuel pressure too low in an injector. All injectors sound perfect though and electrical resistance is 1.2 ohms, so ok ?

If I could give this video two thumbs up, I would, thank you for existing.

It works my l 180is runing

Great👍

I have the same 3 valve engine, I was bleeding the top (return fuel line?) and instead bled the bottom line like in your video instead and the tractor came to life.

Nice video 👍🏻 just have to remember to keep refueling the tractor 😂

Good video. If you just change the fuel filter do you have to bleed the injectors also?

What is fun is doing the above in a seaway.

you can do this on any diesel engine? twice this week ive got very low on fuel to the point it was nearly dry and its now started hesitating and momentarily losing power even with a half full tanks , just like it was before i made it to the fuel station so if i crack open the injectors slightly it will remove the air ? thanks

Hey wait a minute, where's the blowing snow and minus 20c and a battery that doesn't hold a charge very well, isn't that when you usually run out lol??

My tank is below the engine, it’s a generator. I’ve never had to prime it but eventually I will need to change the filter. Hopefully the little hand crank will do it

Thanks. Won't again!

Some machines have a pump ball or you can install one I can Pump Fuel all the way to the injector pump on my bobcat

You actually crack the injector pipes turn engine and watch till no bubbles then tighten unions up the reason fuel has to be higher is it may be gravity fed a car or lorry dosnt matter as the have a fuel pump if it was true for lorry or car you would need fuel tank on the roof lol

Acouple mistakes, #1, why are you running clear road taxed diesel instead of non taxed off road dyed diesel?, #2, isn't there a bleed screw ontop of the cav pump? Looks like you skipped that part also. #3, you can leave the injectors open till it starts leaking fuel. And you can than close #2,#3 and leave #1 open smditll fire snd fun bad but it'll run than you hop off and close #2,#3. (Best to have another helper on this type of job.. OTHER THAN THAT, GREAT VIDEO!

Diesel fuel injectors have plungers , fuel nozzles operate on pop-off pressure as in this model of a Ford industrial tractor .

My fuel tanks on my truck r 2 feet lower than my fuel filters. Any suggestions?

Thumbs up! :^)

Great video. Saved my this week! I have a new to me Ford tractor that looks EXACTLY like yours. Can you tell me what year and model yours is? Mine came with no paperwork.

Sometimes (i know it isn’t good) you can use starting fluid and it gets the air and everything moving out fast. If you don’t have enough battery and you are a good distance from home, starting fluid might be your saving grace. Just don’t use too much

During the part where you bleed the injectors, why not just crack them open, then crank the motor a couple of times, then tighten the nuts at the injectors and then crank the motor again? Doing it the way you show must take some time as I'm sure the process has to be repeated more than a few times. Why the need to keep going back and forth? Especially if you have a friend who can watch the injectors while you crank the motor watching until all the air is gone. In addition, I understand bleeding the fuel filter and pump, but why the need to bleed at the injectors at all? Why not just keep cranking the motor until it fires up? Wouldn't the air that's left in the fuel system just escape on the cylinder exhaust stroke? Anyone wishing to furnish answers would be much appreciated. I apologize in advance if these questions are rather obvious to those in the know. These are things I've often wondered about on diesel engines that's all. Thanks!

Can we not open return to air to got out through top of injectors

Hey i onow this is an older video, just for fun i watched it. I like the video. Um just a few comments. I run diesel and all of my filters are higher tge the tank i cant help it. Now also as primiing the high pressuer pump wide open throttle during prime doesnt hurt. As long as ur dispersing the air w fuel. Nice vid.lol

Love the muffler. I bet you get an extra 20 hp with that thing.

Any thoughts on the hydraulic loader arms being in the way of the battery swing out tray? I can access the first two injector lines but getting at the third one is proving to be problematic.

How would you know all the air is out of the first step top of the fuel filter

Any suggestions for starting innova for airlock n battery desd

What if fuel tank is lower level than the filter?

Does this process use up a lot of energy in the battery? Is that why you say make sure it is charged?

Not all diesel systems have their fuel tank above the filters.

How to start innova when diesel is empty n air lock

It’s not quite like that on all Diesel engines. My fuel filter sits significantly higher than the fuel tank.

spray easy start down the air filter - then it will start - air out done .

Use lift pump so you don’t drain the battery

What do I do if the the filter is higher than the tank?

will this method work on a diesel car ?

Bleeding vw 2.5tdi engine

It seems that I'm constantly bleeding the lines. I see that bleed bolt from the fuel filter, no fuel flows out, no bubbles and I have enough fuel in the tank. Please help

does that turn over with a screwdriver

if you kept cranking wouldn't it eventually bleed itself

imagine teaching people to crack an injector and someone having a limb sliced off by a huey system

Bingo

I’ve always bled my injectors with my engine cranking

Hopefully they say. If your fuel gauge doesn't work fix it. Lol!

Where is the muffler? 😂😂

Running Diesel out of fuel = CARDINAL SIN!!!

😢

Don't let invasive plants rip your fuel lines off

Be glad it isnt a old detroit 2 stroke they arnt that easy
