1/8 NPT Fluid Filled Pressure Gauge
 
0- 30PSI
(0-2 BAR)
 
Ideal for inline fuel pressure for carburettor
Not suitable for fuel injection
See my other items for 1/4" and 3/8" fuel line T piece with corresponding 1/8" NPT
 
This would also bolt onto an existing fuel pressure regulator if it has a 1/8" NPT Port
