What happens when a tank vent gets clogged on a W123.


For anyone that doesn't think the lift pump on a OM617 can practically suck a golf ball through a garden hose....here are two pictures of my fuel tank when the vent became fully blocked for some reason on a 3,200 mile round trip.

Two points of note.....the car never experienced a power loss, and it ran 80-90 mph during all of this. Right up until the fuel gauge suddenly stopped functioning with the only symptoms of a reduced fill-up volume. I drove the car another 4 hours after it crushed down this small, at this point it could only hold 6 gallons of fuel at most.


I guess these pictures are sized too big so you have to click the thumbnails for a better look.
