So, I do most of my own car maintenance, partly because I'm poor and cannot afford a mechanic, but mostly because I'm poor and cannot afford a mechanic. Recently, my car has had an egg smell on the highway, or during rapid acceleration. Best I can tell, this is fuel related, and a quick, easy thing to try is to replace the fuel filter, and run injector cleaner. Well, there isn't a lot of info online as to exactly where the filter is on a 2011 Volvo S40, but one website had the perfect answer...
Kelley Blue Book states, and I quote, "The fuel filter is always located between the fuel tank and the engine."
Um.... I'd have never guessed that a fuel filter would be somehow involved in the fuel system between the fuel tank and the engine. Who'da guessed? Thank Njord for KBB and their top notch mechanic advice. What would I ever do without this knowledge? 🤣
