A follow up on this: kzbin.info/www/bejne/sHzddKSLmrukrJI How to remove the fuel return pipe from the kit without spilling any fuel and how to effectively block the main return and not to have fuel spilling around.

I am fighting with rough idling from time to time which i can't really solve. I never had an ECU update in my 207sw 1.6HDi so it still idles at 833 1/min. I'd love to increase the idle revs but this is not done without really expensive equipment. After seeing your video i now ordered a leak-off kit from Amazon and will check that. Thank you for making these great to understand videos, theis is invaluable.

@@Norgesbeste1 To be honest after breaking my ankle then having a op I was not able to get to it until several months, by then the fungi and mold had taken its toll , I scrapped it as getting professional cleaners in would of cost to much and then you still have spores sitting in places, like behind air vents,and in the seat foam etc , then I would still have to spend money sorting the issue out, Anyway`s replaced for a Suzuki sport 1.6 non turbo, so less things to go wrong with this engine , just suffer from rust underneath being japan make,just a little extra on fuel being non turbo .but sounds nice out the exhaust using its natural flow of air intake giving that resonance note, So all turned out good in the end,😉

you need to put a hole in the caps (white ones) so the air can get out because I found that the transparent tube are sealing quite well on the caps and air is trapped inside. before piercing the caps I got inconsistent results due to air trap resistance

I have a Ford fiesta 1.6 TCDi basically this exact engine… I have an issue with it cutting out… i prime the fuel again and it starts up and runs an drives… if left for a few days it won’t start? Any idea what this could be? I have replaced Fuel lines that run across the top of the engine but not the leak off line Fuel rail pressure sensor Fuel pump sucker solenoid Crank sensor EGR valve Any help would be much appreciated thanks 🙏
@moremolecules

Most likely you have a small puncture in the fuel lines somewhere. You can replace the fuel line that goes to the priming bulb, temporarily, with clear tubing and see if bubbles are forming when it does not start. It is likely that some of the fuel lines are leaking somewhere, it could be the quick release connectors or the fuel filer somewhere. When you prime it, it is a one-way valve, so you are basically purging the system of air until it is left and air goes inside.

I have a question for I would like to do the same test in my Peugeot partner blue hdi 1.6 I have a Sealey vs 2048 diesel injection leak back master kit. but mine return leak hose pipe doesn't have the clip when you remove the pipe it has in the top to a plastic when you remove and by refitting just push down the plastic and it clicks in so how is gone effect me by using the tool test because of different design of my leak hose returner. much appreciated if you can give me some advise .

@@Alex34417 Ahh, I got it, mine is with a metal clip, yours is just push-fit type thing. As long as the push fit thing is the original it should be OK. If you see it leaking, just stop the engine. It is diesel, so much more difficult to start a fire, so not that much of a problem. When I was making the video I had not secured one very well (had to re-film again) and I simply stopped the engine and then secured it correctly.

More molecules ,, i have a last question i hope is not gone sound stupid because of my lack experience with cars when you remove the return leak hose pipe ,I noticed you pushed in the the injector nozzle to prevent air going in so when you turn the car on so no fuel comes out from that pipe ?
@moremolecules
@moremolecules 4 жыл бұрын
It's a good question! Basically yes, this is the return hose to the fuel tank. Any fuel that is "leaked-off" will be returned to the fuel tank. The injectors are under immense pressure and not all fuel is used, there will always be stuff that is "returned". The whole system is closed system, I blocked this, so air does not get sucked back in the fuel tank, but it is not entirely crucial. It is easier to pressurize the system afterwards, although probably does not matter that much, but is a good practice to not have fuel spilled everywhere.

Not too sure about the fuel filter, unless it is really old and clogged. Of course, if you have changed the fuel pump the filter should be changed as well, but doubt it will help you much. Leak off the injectors to see if you have other problems

@moremolecules
@moremolecules 3 жыл бұрын
Hi Catharina, did you use a reamer tool to clean the seat of the injector? If the injector seat is not completely flat it will leak as the seal will not seal that well. You do not need to completely resurface the injector seat (where seal falls on), but just a few micro meters to be flat.

@@catharinacarroll7908 No worries. E-bay has plenty of these, but I cannot give you much info on quality, as I have not tested them. See here for example: www.ebay.co.uk/itm/282649652157 The wall is not that a problem, the seat needs to be flat for the washer to seal against. It depends on how clean it was to begin with, but if you are applying 16Nm and still leaking you need to clean it well. These are copper washers and will distort to cover indentations, but up to a degree. Have a try with one of these reamer tools and it should work. Do not use it to a degree where you would need 2 washers 🙂

Yes, I know what you mean and I have had it on my to do list. You need to disconnect the two pipes coming from the tank (on the left of the engine, push fit clips) and bypass the fuel filter. Basically the same push fits with a pipe straight connection, in other words you bypass the filter. You need to also make sure there is no air in the system with squeezing the bulb-type thing on top of the engine.

Yes, you probably have air trapped in the fuel lines. Try pumping the rubber bulb/pump until you hear no air going through or until hard. Basically, you want to get through a large amount of fuel from the fuel tank through the fuel system until you have cleared it from air. See if that helps.

Yes, if the injectors are new they need to be coded in the ECU. If you are just replacing the washer, then there is no need to program if they are put in the same place. There will be code on the injector itself that needs to be coded in the ECU with Diagbox (Lexia for Citroen, PP2000 for Peugeot).
