Thanks for all your very helpful input. Enlarging the hole in case the ring doesn't fit through sounds interesting, shouldn't be too difficult, avoids having to unmount the tank. I'm determined to get this settled. The strainer is for sure one thing to check, so maybe I will need to enlarge the hole...

Ok, thanks, this is exactly like I have (I was looking for that drawing but didn' find it, don't know why)... What you call a "big plastic nut", I can't find it in my car nor in the drawing, I only see the fuel tank ring (pos. 5 in drawing), which is exactly like in drawing, a large metal ring with ...

I just took a quick look at the fuel tank inspection hole under rear seat. I'm not sure if I can gain access like this, as the metal ring (it is supposed to be removed by unlocking it, with screwdriver and hammer or similar trick, right? or is this a different system?) seems to be bigger than the ho...

What you're saying makes absolute sense. The one-way vale in fact acts as a added restriction, which would cause exactly what you're saying, if the strainer is blocked. It could even happen if it was not blocked, if in fact there were several small leaks. Good explanation! Today I decided to make su...

Thanks, no problem :wink: That's good news, I will check the strainer if I can't get this sorted in the meantime. Today I made some experiments and took some photos which I send attached. First, the photo of the one way valve: IMG_20211101_160207108_.jpg I actually interpreted this situation wrong a...

Thanks for the quick replies. First, this engine has been modified: it has the Bosch pump fitted. I have NO idea if they fit the electric lift pump to the tank or not. I guess it's necessary for the conversion? I'm going through this point by point. - The valve was bought NEW from a auto parts deale...

I finally found the time to install the one-way valve into the fuel feeding line, right after the primer bulb, so to end the fuel running back to tank issue when parked uneven. I'm certain that I did it well, the tubes are sitting really tight and I installed hose clamps on both sides, no leaks. But...

Just (tried) the cleaning of the sunroof drain tubes thing as described in the topic in the knowledge base section of this forum. Unfortunately, my car seems to be the "odd" one that is different (or has been modified by someone... been there already too many times... seems like since the start, in ...

Thanks, but I fixed this already, forgot to post here, sorry... The problem was: someone had dislodged the terminals INSIDE the connector for the passenger mirror so that they would not engage even with the connector in place, instead of simply disconnecting the connector like they did in drivers mi...

I'm looking forward to this being discovered by a moderator, so to see if it might be a good idea to move it over to the how-tos section. 'tis done. Took me a while as I couldn't remember how to do it :oops: Great! Hope this might help someone, somewhere, even though these engines are already to be...

Thanks, some useful points here. I don't know, it might even not be as bad as in the HDI, but for sure it does go right there down into the inner wing, which is kind of scary... so I definitely want to improve this, precisely because I don't want to risk losing mine, as this appears to have happened...

Weather has been good so far, so I went for other priorities and haven't had the chance to do this yet. Instead, I changed the rubber junction pieces of the upper inlet manifold with the lower inlet manifold, they were leaking oil badly and I also cleaned the upper manifold. This maintenance/repair ...

After finding the warnings on this forum (and other places on the internet) about the air intake of the 406 being dangerously low (or creating some strange water sucking situation, whatever it is), making it a high risk to drive through any standing water, I'm really decided to change the air intake...

So, I just did this. Wasn't difficult at all. But I still took photos during the process, so I'd like to make a small How-To here. If it turns out well done, maybe someone of the moderators could move it over to the knowledge base section. How to change rubber interconnection seals of upper to lower...
