The other post got me thinking. Sometimes my fuel pump
seems to be struggling and making a loud whining noise.
But not all the time, just sometimes. Anyway when i fill my
gas tank at the end of the week and undo the filler cap there
is a loud whoosh.
Is there some sort of breather hole, and i guess mine is blocked.
where is it on a 1998 190E 2.0 manual benz.
suggestions welcome please.
I agree on with AJDalton.
The same thing happened to me (loud whining noise to start with) on another
type of car (280ZX) that had the fuel filter placed after the fuel pump, not
in front of it, like the Mercedes set-up. Rust and junk in the fuel tank
got into a thimble sized pre-filter on the intake side of the fuel pump that
was built into the fuel pump. Eventually I lost power and then the car very
suddenly would barely run.
I cleaned the pre-filter and cleaned the gas tank out (lots of rust and the
remains of the lining of the tank came out) and everything was fine for
awhile. It happened again and I cleaned the pre-filter again and decided to
put a filter in line on the intake of the fuel pump and I'm good to go
again. Eventually I need to replace the fuel tank as the lining is shot.
Change your fuel filter and check for rust and junk in your fuel tank.
