Hi My name is ***** ***** I am a fully qualified technician i will try and help you.
Just to confirm I am presuming that your Beetle is petrol and not diesel.
As well as the fuse there should also be a fuel pump relay under the bonnet, this should be in position 4 but you should check your handbook to confirm.
If you can hear the fuel pump running then we should hopefully be able to confirm that the relay is ok, but its always best to check and I would examine it to ensure it has not been overheating. This may even have been the reason for the fuse blowing.
Assuming that is all ok, you need to ensure that even though you can hear the fuel pump working, that it is actually pumping fuel. It could well be the case that the fuel pump has been the reason for the blowing fuse, but is now running without resistance and not pumping. That may be the fuse isn't blowing now.
I hope this helps but please get back to me with any further details and I will do my best to help.
Please if happy click accept and rate, you can still continue to ask any questions even after doing this.
