Frequently asked questions

Which thread does my LS use for the oil pressure sensor?
Gen III LS engines mostly use M16 x 1.5, and many Gen IV use M12 x 1.5. Check the old sensor thread before ordering.

Are AN and NPT the same?
No. AN is a straight thread that seals on a 37 degree flare. NPT is a tapered pipe thread that seals on the thread itself with sealant. You need an adapter to go from one to the other.

Does Australia use BSP or NPT?
Both turn up. Most American engine parts, gauges, pumps and senders are NPT, while some local and Euro gear is BSP. Check your port before you order, they do not interchange.
