Hi all,
i'm probably just being overly cautious here, however, i noticed just before that the sound that my Walbro intank pump makes has changed today.
it is probably only 3 or 4 months old (tops) and it usually makes the normal aftermarket fuel pump whirring noise, yet i noticed just before, when i moved the car, that the noise has changed.
i can't describe how it has changed, other than it being a bit louder, and the noise seems to be a bit 'deeper' in note...
does it sound like anything i should worry about?
