oil pressure sender thread?

[REGGY5GT]

Looking to buy an aftermarket sender for my b18ft to get my oil pressure auto gauge working, heres the link- http://www.ebay.co.uk/itm/AUTO-GAUGE-OIL-PRESSURE-SENDER-SENSOR-UNIT-/370568501670?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item56479a99a6

i could do with knowing the thread of the standard oil sender to make sure the one above will fit, any help as usual will be appreciated. Tim

Did you get a sensor with the kit you bought? I bought a aem kit and the sensor fitted into the original sender. I just split the volvo jobbie fitted an adaptor to match the two treads and it works fine.

I can not remember the size for you mind :)

No unfortunatly phil I didnt get a sensor as the gauges were already in the car but not plumbed in,i also have oil temp and water temp in the tri holder and tbh I wouldnt trust the oe oil pressure gauge,ive read that the majority of cars use 1/8pt or something around those lines,could do with confirmation really,also im unsure whether to 'T' into the oil pressure switch and have two gauges or replace the standard sender with one thats calibrated to my aftermarket gauge?
