Don't Be Fooled By THIS DAF Fuel pressure fault LIKE I WAS!

[@MasudBinYussif]

You are a great technician Keep it up my brother l. God bless you

[@Diederik240]

This happens to every technician sometimes... Thank you always for your informative video buddy!

[@TRUCKTECHUK]

It's just one of them things 🤷🫣 I'm glad you enjoyed the video buddy 👍👀

[@zivotamilenkovic]

Not, you are not idiot, lesson learned. Thank you god man for your lecturing. God bless you.

[@jamesherrick4927]

I've learnt a lot of watching your videos, mate. we run dafs and had a few fuel pressure faults, and watching your videos helped a lot in sorting our dafs. Don't kick yourself too much, mate. we all have brain farts now and again lol😂 keep up the good videos.

[@allyally5359]

Great video like always👍💪. But be aware of the fuel filter module in the top you have a white ball made from plastic and sometimes it is missing and you have the same problem low fuel pressure , or in the fuel filter there is a pin on inside and that pin is broken when the mechanic is changing the filter and there is the same problem low fuel pressure. Keep Up and God Bless You.

[@TRUCKTECHUK]

Hey Ally thanks for the comment 👌 😎 😀. I've had the non-return ball disappear into the filter base before I didn't know of a pin inside buddy I will have a poke about the next time a filter is out 😎👌 Thank you 😊

[@BoazMakina]

Humble way of teaching. You are a great technician my brother. Keep it up. I have learnt a lot from this video .

[@TRUCKTECHUK]

I'm glad you enjoyed the video. I'm not afraid to admit a mistake..especially one everyone can learn from such as this. Basic checks first ALWAYS 👍😎

[@edwardreyes6867]

Thanks for showing that sometimes we all overlook the small things! Happens to all of us lol. Greetings from California, USA!

[@TRUCKTECHUK]

Hey Edward 👋 Thanks for the comment from across the pond! We're only human at the end of the day! Me in the diagnosis and the tech who fitted the filter. Let's just say we BOTH learned the lesson from this

[@alancharlton109]

Fair play. I’ve been lead down that path before. You just assume because it’s been serviced it’s been done right. Not always the case. I’ve worked at Volvo and Scania both have their share of below par techs

[@TRUCKTECHUK]

Hey Alan, thanks for the comment buddy. 100 per cent agree with you....when you're presented with a fault, you HAVE to start at the beginning. My problem is I'm too trusting 🙄 and that lands me in hot water 😶‍🌫️

[@alancharlton109]

@@TRUCKTECHUK I used to be too, these days a lot of the jobs I do are other peoples f*c^ ups so I’ve learned not to trust anyone

[@Tubecraft1]

I think you were on the ball because other people wouldn’t even have noticed the old seal down in the housing. Well spotted! I once replaced an oil filter on an O&K loading shovel deutz engine and when i started it the filter burst I couldn’t believe it coincidentally the pressure relief valve stuck at that very moment- had to change the oil pump then all was fine - then people wonder why we hate this job sometimes

[@TRUCKTECHUK]

Hey mate thanks for the comment 😎👌 . I usually drain down the fuel filter module but without the pipe, I could just see it in the diesel in the filter housing! Ha ha ha it's always the same isn't it! I remember when the DAF LF started to get high oil pressure faults blowing the front seal because of the pressure relief valve sticking........3 seals they fitted before I said something going on here buddy! Yes I was annoyed that morning too with the job and myself lol

[@PH-Truck-Mechanic]

it still happens, the little things are the hardest to detect... once I had to deal with a MAN TGA with the message "low oil pressure", everyone said it was the oil pump, but I found out that the driver he did the oil change himself not long ago and I said to check the oil filter and surprise, the diesel filter was instead of the oil filter

[@TRUCKTECHUK]

Hey Paul 👋 Thanks for the comments buddy 👍. It's amazing how you can even fit one filter instead of the other on a MAN!

[@stevesauerland223]

Good video. I would of done the same since transfer pump restriction was correct, but output is low. Who would of thought filter was damaged allowing it to bypass straight to return. Guess you could of deadheaded pump to confirm pump was bad.

[@simonellis5303]

Hi Russell proper techs will admit to boo boo’s. I myself have believed what customers have done or another tech. Why should we disbelieve them??? But I like you have on this video found out the hard way. I have put it down to a big learning curve and always remember to start from the beginning now not believe what anybody has done before me. Hats off to you for showing it off on here. Many techs would never admit to that and have spent thousands on it and blamed the expensive parts. At the end of the day we are only human and we learn every day on these complex systems. Keep the videos coming Russell and take care mate

[@TRUCKTECHUK]

Hey Simon nice to hear from you. Thank you for the kind words 👍. You are right can you imagine a customer saying I've rebuilt the engine and my first answer is "I need to rebuild it again as I don't trust your workmanship!" It's a fine like to walk going back over things people have done to ultimately find out faulty workmanship was the answer as opposed to being a component issue. I don't mind admitting to it or putting it on here as long as people learn from it 🫡 You are right as every day is a learning day 😎 catch you soon buddy 😉 👍

[@darrenhearn1365]

Another good video, I think we've all fitted s part or two to make us go down another route, I know I have !😶 It still amazes me when you do it the problem gets worse !

[@xl447]

Fair play, found in the end. We've all suspected the worse, jumped in feet first and over looked the obvious steps first, but the old bits were out of sight, out of mind. Had similar last year, previous fitter simply split the filter seal on a Scania 94 with poor starting, you assume the filter should be ok. Still a hard core Texa user though 👌

[@zachc2991]

Very well put together videos. Great content. I hope Cojali is hooking you up for all of your good marketing of their tool.

[@TRUCKTECHUK]

Thanks for the comment. Yes, I have a good relationship with Eclipse Diagnostics which is the UK distributor. I've a few Cojali tools here also 😎

[@StaticVapour590]

Well that was a first time you saw such thing, small human error :) Seen and heard similar thing happen on cars and vans with oil filter housing at the top (usually catastrophic if not caught), but never with fuel filters due to them being usually spin-on filters or in-line ones, some manufacturers use cartridge filters.

[@TRUCKTECHUK]

Hey thanks for the comment 👌 😎 It was amazing as it shouldn't have fitted 🤯😆🙈 I miss the spin on filters. You couldn't go wrong 🤷

[@mauritztoivonen1070]

Seenit and done it.Thank you from Lappfjärd Finland.

Hey hey thanks for the comment as usual buddy 👍 😀. Yes won't be the first or the last time I guess 🤯

[@kdo2487]

One time i did maintenance on a mx13, when changing fuel filter i got to look at 2 seals haha! Weird enough it didn’t had fuel pressure problems though!

[@Meenyservices]

Great work! only human , solved it in the end 👍🏼

[@TRUCKTECHUK]

Hey, thanks for the comment man 😎👌

[@benyapetri]

Hello friend, thank you for the important content, exactly the same problem happened to me. I changed the fuel pump and the presure was still low, after I changed the fuel filter and the pressure returned to 7-8 bar. The filter was aftermarket, I installed the original paccar filter and it was ok.

[@codexTu]

What brand was your aftermarket filter?

[@benyapetri]

Purro

[@decthailand8573]

It happens to us all ,keep up the good work ,do you get many faults with dpfs on LF E6 67 plate

nice work mate that 1 took you down the garden path

[@jakepotter3687]

Have you got any plans on making a test kit for the Cummins fuel systems?

[@TRUCKTECHUK]

Hey Jake, I take it you mean mean the LF system? I've been doing a lot of LFs recently so I will look into it 👍I need to get my high-pressure system for the MX engine finished and out first 🤣🙈

[@jones3498]

Just curious. Did you take the new low pressure fuel pump back off as it wasn’t needed or not? Really enjoy your videos

[@Memphis67]

Great work! I am a subscriber of your channel and have learned a lot of new things! I have a question: MX13 engine, engine oil gets into the fuel system, the fuel turns black. Everything works properly, there are no error codes. Where should I start to find the cause and fix it? I understand that these might be the O-rings on the PLD sections? Or could the PLD section itself be damaged? and oil passes through it into fuel, does this happen?

[@drivewasher]

Thanks for this video, What happens to the new fuel pump you fitted. Will it go back in stock?

[@TRUCKTECHUK]

Glad you enjoyed the video. I have no idea what happened to the fuel pump, I ensure I acquire authorisation for parts to be fitted to vehicles during diagnostics.

[@drivewasher]

Our Chris recently bought the breakout leads and resetable fuses for me. (Ashcroft's mini travel & coaches) He thinks I'm Paul Daniels LoL. You delivered them personally Thank you, I'm following your DAF Paccar videos closely

Can you help? Dad cf 75 310 struggling to start. Lots of changed parts and filters and even new injectors! Still turning over lots before starting

[@TRUCKTECHUK]

Hey Mathew 👋 thanks for the comment mate. What year is it? Either way, I'd be looking at the requested fuel pressure and actual fuel pressure.....depending on whats going on I'd be working my way up the low-pressure side of things and onto the high-pressure system. Possibly bypassing pipe work depending on where the tanks mounted

[@matthewbriggs-price6755]

It’s 56 reg 6x4 double drive,lovely truck. Do you fancey a ride to Newark to have a look I’m getting desperate 🙄

[@myscaniav8power1]

It's quite common for this to happen. before changing any part, check the filters first

[@preslavvasilev7387]

It also can be damaged bearing on the air compressor - symptom is hard steering wheel. I have struggled with missing middle ring on high pressure pump unit on xf105 😂 Hit like button in the beginning in the end have to dislike or what. Great vid buddy. Sometimes it takes time - normal things ⚙️🔧

[@TRUCKTECHUK]

Hey Preslav 👋. You know what I was standing next to the truck thinking.......is this a compressor bearing issue but its 2018 but It would have had steering issues as the compressor would have snapped the power steering shaft.......I had that on the side of the motorway on a daf aid at 4 o'clock in the morning once lol Ha ha ha everyone needs to hit the like button lol 😆 its not very often I manage to miss something so I'd rather show people than pretend it never happened 😉

[@joshuapeaker]

Been there done that. No matter how many times you tell yourself to check other peoples work the one time you don’t is always the time you get caught out. 😂 Oh well we’re only human.

[@norb0254]

How the hell did they get that filter in and the cap on with part of the old one still there ?!! ..It will not be the first or last time any of us get caught out by what someone beforehand has done ,even though we say we will always check it ...What i didn't get was you checked the filter in the hand primer ,and i though next you where going to check the fuel filter ,was it new and the correct part number ,,I was also puzzled when you check the tank filter after confirming there was no excess under pressure ,but i can see why you did ..I once had crap stuck in the chassis to engine interface ,,and in a brand new truck a bit of plastic ine the pipe from the tank to the interface that would float about and then block the interface when under load ..Strange bit was it was to big to get through the brass fitting so must have been in the pipe before the couplings where fitted ....You can't fault the gauges ,but people don't like using them...Another thing i do is with davie connected and reading fuel pressure ,i hand prime the hell out of it with the engine running ,if i can raise the fuel pressure by hand ,then you are looking at the lift pump...I take it the jaltest can't store a chassis number ,so if you revisit it can id it and the systems ??

[@TRUCKTECHUK]

Hey Norb nice to hear from you buddy! Mate the filter was like a jack in the box....you can hear the threads creaking when I'm undoing it lol it I checked the hand primer filter and you know how much of a pain in the arse it is to get the gauge on in the chassis when you can just whip the hand primer out. In my eyes, the wrong filter means the truck won't start. With the hand primer looked like it was brand new and the customer informed me they had changed the filters I steered away from even bothering to check the fuel filter as I had come complacent unfortunately. I checked the tank filter after using the gauge because you can never be too careful......how IRONIC ha ha ha 😂 I could get fuel pressure to rise on jaltest manually via the hand pump but only 0.5 bar which was different from when I sorted the fuel filter as I got 1 bar out of it....I've never tried priming the fuel system while running lol other than cranking All in all, it was an odd one 🤔 that meant things were not your typical A,B,C. As for jaltest it stores customer details and data even test plans and actions you followed

[@norb0254]

@@TRUCKTECHUK The beauty of fuel faults is sometimes it is just easier to ,pull the sender ,and see if it has a filter for a start, do the hand primer filter and change the fuel filter ..I did chuckle as you obviously watch the same clips i do ,ref the U'S MX engine and fuel issues lol...Since i am now on god knows what camshaft or engine change ,I know strip the filter housing then i have it removed .that way it is perfectly clean ,as you know what they say how X amount of fuel faults are after major repairs ,and there is another filter inside the base ,which i would say so far 25% are blocked ,and i would say it is all because of biofuel ..I hope your business is going well..The problem as you know with our side is getting paid,and the queries to delay payment..I bet your heart sank after downing the turbo to then get another call

[@TRUCKTECHUK]

I'm quite methodical and to the point with fuel faults on low and high-pressure sides usually but this last month I feel like daf trucks have had me over a barrel lol I did a high-pressure leak-off test on an xf which turned out to be PUMP UNIT number one camshaft lobe TURNING ON THE CAMSHAFT And this bloody filter job!!!!!
