Whilst playing with my fuses i noticed my fuel pump relay was hot, hot enough to make the plastic cover sticky (melting). I removed it and tested it and it seems to be working correctly.
Anyone had this problem before? I vaguely remember reading that this is a know issue in MK3's as relay came from portugal????? (details sketchy)
Might run a wire to earth from the neg pin and see if it gets hot, if it doesn't it must be faulty relay?
