As pictured above the stock Mustang pot has 2 venturis and 1 refill umbrella valve.

1 venturi siphon is used to draw fuel from the RH side of the saddle tank into the fuel pump bucket

1 venturi siphon is used to draw fuel from the LH side of the saddle tank into the fuel pump bucket

1 umbrella valve is used to ensure the bucket allows entry of fuel surrounding it at all times without allowing it to re-escape.

The stock Mustang fuel pump delivers approx. 272lph of fuel when under maximum load.

The venturi siphons must keep the bucket full, therefore must draw in excess of 272lph.



We have posted a picture below of a KPM fuel bucket that is used on all the Mustang fuel module range that we manufacture.

The KPM bucket has 4 venturis and 2 umbrella valves

1 venturi siphon is used to draw fuel from the RH side of the saddle tank into the fuel pump bucket

3 venturi siphons are used to draw fuel from the LH side of the saddle tank into the fuel pump bucket

2 umbrella valves are used to ensure the bucket allows entry of fuel surrounding it all

The large KPM 1500 fuel pump module delivers approx. 600lph of fuel under maximum load Therefore we have incorporated the extra venturis and umbrella valves to ensure that the bucket remains full under every possible scenario by drawing in excess of 600lph.


This means all KPM fuel modules can continue to draw all the fuel required under full load down to a near empty fuel tank.
