hi guys just got off the phone to GSF car parts - few easy questions - they dont stock a golf VR6 header tank, just a normal mk3 one they said. do you know if this will fit my golf vr6?? also my temperature gauge on the clocks wont go above 70. in my thermostat housing i have one blue 2 pin sender and next to it a 4 pin yellow sender. GSF only stock a 2 pin blue sender, is this the one for the temperature gauge on the clocks? he also said mine shouldnt be a yellow 4 pin sensor, said it should be a brown one.
