All the right fittings. (BSPT<NPT, NPT<BSPT, & a 1/8" Tee)



One is a 1/8" BSTP to NPT, the other is NPT to BSTP.
Our stock sender has BSPT (British Std. Pipe Thread) while most gauges are NPT (National Pipe Thread), so we need a male BSPT with a Female NPT to screw into the block. And also a Male NPT with a Female BSPT to screw the stock sender into the Tee fitting.
