9 flow jets cover a V8 nozzle system with 8 of .024 .026 .028 .030 .032 .034 .036 .038 .040 fuel jets.

Just need a digital pressure gauge?

The different size jets used with this tool simulate the pressure at your jets or nozzles.
The "flow jet" is the same equivalent area as your total number of fuel jets or nozzles.

How and why it works:

The on/off valve simulates pressures of the solenoid open or closed.
