Can you fit both of the sensors in that area?? Been looking at some bits and pieces and found that there is meant to be 2 threaded drillings on the filter mount or is it a case of getting an adaptor with more thatn one hole and doing it that way as i would guess the car would have probelms if you disconnected the OEM sender.
The gauges are the ones that you sold to MK1macca Jordy
