Hi, are theses all fit in psev tanks fuel pump compartment for E350 2008 ?!
Analysis of Fuel Tank Leaks, Model Years 2003-2008

The module for the S55 looks identical but it is not, it is very close and could be modified to work but what I did was to take the S55 module apart and remove the new pump and filter. I then used these parts and installed them inside the PZEV E350 Module. Perfect fit, electrical and fuel connections are exact fit. The pumps could be swapped in 15 minutes so don‘t let needing to use the old PZEV Module scare you.,
As far as sealing, fuel leaks past most all sealers. The route I chose was to use the Neophrene gasket that was supplied with my new fuel pump door assembly. JB Weld will not do it either. Fuel causes most things to leak. Silicone turns to grease when exposed to gas vapors. The only change I would do is to install a slightly smaller removable door If possible.

Hello West, could you please recommend diameters for
Opening
The screw's thing
Geskets and it best material .I mean what I have to get aside from the pump
Thank you
Your approach is going to be applied overseas
Hello Mark, I have two questions
1st the order is metal support open ring inside the tank, the gasket outside the the cover plate on top of the gasket then screw the screws. Right?
2nd question please..Considering you have done this as the first one and first time you really needed to remove the tank.. now as I have your awesome fully decumented experi6, do you agree with me that I can do this job with the tank unremoved from the car of course after I assure it empty and clear even from fuel odor?
It has been quite a while and my memory is not perfect but I think you could use a 6” cover for this job. I believe I shared measurements at some point in the write up above. As far as cutting the tank inside the car I would say NO WAY. Gas fumes will sit in the fuel lines and tank and provide a perfect source for a fire or explosion. There must be 6 feet of fuel lines inside the fuel tank. My father worked with tanks in the past and warned me Forcefully to not even consider that route. With the tank removed I filled it with soapy water before cutting. It is very tempting to cut in the car but I just can’t see that being possible without fire risk or without leaving a lot of metal inside the tank. The fuel pump is perfectly centered inside the PZEV tank right under the area where Mercedes should have installed the tank access. The 8” cover I used was large enough that it was very hard to remove the screws and take out the cover with the tank in placej. I actually lowered the tank a little to gain the clearance I needed when I put in the second pump but that was only 4 bolts to gain the little extra space needed so for sure the 8” was too big But I made it work. The plate needs to be larger than the access hole to allow for the backing plate, gasket and screws. The plate I purchased was aluminum and it worked just fine.

If you read thru this thread, the poster West successfully added an 'access cover' to a PZEV fuel tank to enable fuel pump replacement. West cited the cover that he used and it uses threaded studs, nuts and a rubber gasket.
This is how the newly added 'hole' in the steel tank was sealed with the newly added access cover.
The notion of 'sealing' a cover like that with "RTV" is a recipe for a mess since that cover region is partly below the fuel level when the tank is full of gas.
The 'retrofit/conversion/modification' of the PZEV tank is not a job for everyone as it's not easy, but it can save a LOT of money if one is up to that kind of a project.

Dear Mark,
Thank you for your time and valuable life saving recommendations 🙏.
I know it's not an easy job if done safely.
My first option is to send the car 1000km to the only dealer in Libya so they check and let me know if it's covered by the warranty which is costly and unlikely to happen!
If not covered they replace it with another stupid PZEV tank for 15000 LYD.
Second option scrapyards 2000 LYD for replacing with another w211 normal tank with all its belongs and connection guaranteeing the pump but not guaranteeing engine check lamp off and tidy! The possibile incompatibility is fuel pressure sensor which is likely to cause check engine light 🚨.
Third option which is the lowest cost and happy ending 😁 is your way 😉 providing I could get the accessories from cover and screws ring to the proper gasket.
This discussion has a great value and so useful .. of course more than a punch of mercedes-benz engineers
Thank you again dear Mark wish you the best and
my sincere regards
You are welcome, these are still very nice cars and to see one scrapped because a fuel tank needs to be replaced is just silly. My repair was a lot of work but removing and installing an entire new tank to fix a fuel pump is also a lot of work. For those that have not done this it is not for a light duty wrench. The entire exhaust, driveline, and complete rear suspension has to be removed to get the tank out so you do not want to take this job lightly.

Right
Keep in mind the guy in the video had a lift, a jack that held the tank up etc. I did mine with a floor jack, no lift, just put the car up high, about 24” off the ground on good jack stands and went to work. I pumped the old tank empty before trying to remove it. Gas is heavy if left in the tank making the job very difficult so drain the tank Before starting this job.

Hi Mark Yes in deed, tools are half of the job.. I woul do that in one of the rented garages with all needed tools included. You know what's stopping me so far, it's the metal ring with screws in picture below.. I haven't managed to get one so far!!
The ring and cover were aluminum. The screws went into brass inserts I think. I do not remember the name of the company that made and sold these parts but it should be listed in this thread early on. Another forum member found them for me and I ordered on line.

I have a 2007 e350 California car that recently started to smell of fuel, it is leaking from this unit(picture below). I read comments in this youtube video(also listed below) that it can be replaced. What I have not been able to find is a confirmation on the part number for it if it is in fact replaceable. Is it the same as #171 470 08 90. I understand epoxy may be a half measured solution but I may use it temporarily if I can seal it better than it is, right now the only other solution I have found is to replace the whole gas tank. The fuel pump is still working fine.

What's the vin? It's either a regular car or a Pzev, could be either. The regular car had a 15 year extended warranty on the gas tank with no mileage limit. Probably expired by now unless it was sold really late as they go by the in service date of the car. The Pzev had a 15 year/150k warranty but also probably expired by now. The pump part number are different depending on the car.

I contacted mbusa I missed the warranty by a year. I had no previous knowledge of this until today. Unfortunate
Yes, your car is a Pzev. Then this whole thread should apply to your car.

yes, but I did not see if the part I was wondering about was replaceable or not. Thats really what I am curious about at the moment.Yes, your car is a Pzev. Then this whole thread should apply to your car.

I’m not sure if the driver side unit is replaceable in a PZEV tank. If it is, don’t forget the pigtail that connects the pressure sensor to the car harness. I don’t know why MB redesigned the connector.
The driver side unit looks like it can be removed but with a non-PZEV tank you have to remove the fuel pump to detach interconnected hoses.
