Does anybody know what the oil pressure sensor thread type is on a na/s4 13b i believe its an 1987. Is it 1/8" BPT Or is it NPT, the reason i need to know this is i want to put a T in so i can run my oil feed line to my turbo. Will a basic ebay oil line kit work or do i need to buy a bunch of fittings? Trying to see if this will work tho http://www.ebay.com/itm/UNIVERSAL-36-STAINLESS-TURBO-TURBOCHARGER-OIL-FEED-LINE-1-8-NPT-END-FITTING-KIT-/400586823001?pt=Motors_Car_Truck_Parts_Accessories&fits=Model%3ARX-7&hash=item5d44d5d559&vxp=mtr

 

1/8 BSPF 28

most adapters are in 1/8 NPT 27

 

Please clarify if BSPT or BSPP? Since BSPF is not a term I can find if it is parallel or tapered.
As per

But it seems BSPF is BSPP?
