1969 Porsche 911 Carburetor Pump Discharge Vial

Product Description:

Calibration Vial
Porsche® tool number P25a
Sold per each.

This small glass vial comes from Porsche and has ml markings to measure the fuel pump dischage volume on the throttle circuit of your carburetor. The vial must be held down the throat of the carburetor and is best hung on a secured wire. Bench setting the fuel pump discharge volume will greatly assist tuning when the carbs get on the engine.

PLEASE NOTE:  Some disassembly and/or bench measurement will likely be required for Zenith 40TIN carbs, as well as the 911T '69-'71 Webers with 27mm chokes. For these carburetors, there is insufficient room in the throat to lower the vial into position.
