2F Pipe Thread Type.

[Dr. John]

Regarding the threads for the 2F BVSV valves, water temp gauge, block drain valve, etc. BSP or NPT? I was thinking BSP but Holley supplies a NPT threaded temp sensor for the Sniper.

There's nothing on the vehicle that has NPT.
If the threaded hole is tapered, it's BSPT. If not tapered (temperature sender) it's BSPP.

NPT parts have been screwed into cruiser holes before and been forced to work, but the threads are a slight mismatch.

I've always been able to find NPT to BSP* adapters on eBay or Amazon, that's what I'd do.

This is what I used for temp sender recently. The price was ridiculous, but it works...

Hmmm so reading this thread (pun intended) I probably have BSPT going into BSPP. Probably not the best solution, but a few threads must be making a good seal...for now. I guess I’ll look for the proper adapter.

Yep, ordered that one...and a 3/8 BSPP to 3/8 BSPT in order to move the stock temp gauge sensor to a BVSV port on the thermo housing. Had to get this one from DiscountHydraulicHose.com.
The adapters cost more than the sensors!
