I dont know if anyone is still looking for the fitting to convert the BSPT threads on most ports in our engine to NPT fittings, but I found a source here in the USA. I got the catelog in the mail somehow.
The company is called Pegasus Auto Racing Supplies. www.pegasusautoracing.com
- 1 800 688 6946
From the catalog:
1/8 BSP -> 1/8 NPT - steel $5.52
Lots of other parts.
just thought I would throw that out there.
