Nothing, but let me explain my plans.
I've got an F4R in my mk1 and to get the aux gaugues to work i need to put the valver oil pressure sender on a pressure takeoff, so was thinking of putting a t-piece on the pressure switch hole to run both the switch and pressure sender.
I can only find t-pieces that have one m14 x 1.5 and one 1/8NPT takeoff though.
As both the valver pressure sender and F4R pressure switch are M14x1.5 i need to either find an adapter (which i haven't been able to find) or just replace one of them with something that has a 1/8NPT or M10 thread.
I was going to replace the pressure sender for one with an 1/8NPT but didn't know if it would be compatible with the aux gauges, as i don't know what the O.E. spec pressure sensor is calibrated to.
I just thought it would be simpler to get a new pressure switch with the right calibration, but if someone can tell me a suitable pressure sender to go for then I'd just replace that as the valver one is have is probably ancient.
