First off this is mk2 driver with a Weber and a GTI camshaft. Hi guys, need your opinions on this. My fuel pump has literally just started making a funny noise, its the hollow bubbly sound in the video. Ignore the fact the engine is very knock-ey anyway, I'm not fussed about that for the time being! The later half of the video where I move the camera is where I put the microphone up against the end of a long screwdriver to pin point the noise. Neat little trick to those who don't know about it http://www.youtube.com/watch?v=4e7Jst-SwDw Also while I've got your attention, Any ideas on the strange noises from the exhaust, firstly there's the occasional popping, secondly if you listen carefully you can hear the car appears to struggle every now and then, any ideas? http://www.youtube.com/watch?v=QkxmjMEU96k Any advice would be awesome.
