These Valtek type 39 (std) rails have removeable brass nozzles that need to be the correct size for the engine.
The rail is supplied with 1.5mm nozzles.
LPG inlet is 11mm
Injector outlets are 6mm
Resistance is 2.5 Ohms
These injectors work in a similar way to the high spec Valtek type 34 but are even faster acting. This means they are much more accurate and long lasting than standard ‘piston’ type injectors (type 30 etc.)
