1972 Mercedes Benz 280SE 4.5 New in Tank Fuel Filter, Fuel Pump, cleaning Fuel Tank Breathing System

Jun 16, 2022
I replaced the in-tank fuel filter, Bosch electric fuel pump, some fuel lines and sorted out the non-functioning fuel tank ventilation system in my 1972 Mercedes Benz 280SE 4.5. Video shot on June 16, 2022.

Inspiring to say the least. I love how you double, triple check everything. Great car.

Thank you for watching and your kind remarks. It's all new to me so double checking is double learning.

Really nice job on the diagnostics here Ken! The new pump "mod" turned out excellent, as did your tank vent system repair. A piece of upholstery foam would probably work better than the fabric because it would be more 3 dimensional in terms of trapping road grim, yet still passing air. Nice find on the melted line. I wonder if that was it's original location, or if someone moved it there, not realizing how close to the exhaust manifold it was.
It would be fun to see a video on each car, telling the car's history and how you found it, and a nice slow walk around, inside and out, and a tour of the engine compartment. They are all in such great condition!

Wow! Thank you for watching and your lovely comments. I did not think of the dimensional aspect of filtration. Good point. Easy enough to change out. I don't think it was the original location of the line, however, I did find an empty holder that I used.
I had not considered a detailed walk around and known history of my cars. I did not and do not want to bore folks, nor do I want to sound/look like I'm bragging. I really appreciate the complement and feel emboldened now to make them.

@@kensshowtell I think with vintage cars, especially something sort of rare like these, enthusiasts really love to hear about the car's history, if known. It was a fun part of the history on your fintail video. And a nice slow engine compartment scene is always appreciated by us as well, as is a go around of the interior. Not bragging at all, but simply showing the features, engineering, uniqueness, and beauty of the car. Sort of a series on each would make great content.
By the way, the "R" on the fuel gauge stands for the German word, "Raus," (pronounced "rowssss") which means "Out," as in, "out of fuel." The owner's manual probably says how much fuel is left in the tank, once the red light comes on. Probably something like 1 to 2 gallons.

@@austinado16 One to two gallons sounds about right. Danke mein Herr. I definitely will do those future videos.

Hey do you have fuel pump product number as well as the tank filter? My vehicle does this same thing after 30mins of driving

[@kensshowtell]

Thank you for watching. The fuel pump came from Pelican Parts & the # is 001-091-71-01-M14. I purchased the banjo fuel fitting as well. The in-tank fuel filter I got from Mercedes Source.

@@kensshowtell ok cool I'm going to check it out. So did doing all that fix that wanting to die out after driving for the time you mentioned? Happy Father's Day btw

[@kensshowtell]

@@mattcruz9201 It did.

[@mattcruz9201]

@@kensshowtell ok great because I just paid $1k to a shop for it to continue to do the same thing. Seems like you know a lot more than them.

@@mattcruz9201 I appreciate your confidence, however, I'm just an enthusiast who has learned something along the way. Make sure your fuel cap is venting as well. D-Jetronic is totally dependent on maintaining and holding fuel pressure in the fuel rails at around 27-30 PSI.
