You need to either recalibrate the float chamber or buy one ready set up

Kerosene is known as 28 second fuel. ........thats the time a measured amount takes to run via gravity through an orifice of a given size
Diesel is known as 35 second.

The difference is the viscosity.

Kerosene is also known here as heating oil and is the same fuel as AVJET......aviation jet fuel

Its not wise to use kerosene in diesel engines other than as a brief cleanser or winter fuel additive to prevent waxing of diesel, at 10% blend.
Kerosene will soften and deteriorate seals and O rings in some fuel systems.
It can burn in a different pattern in certain cylinders and cause hot spots which the engine wasnt designed for

Red or duty free agricultural diesel doesnt have the low sulfur additives that road fuel has, it produces marginally less power and requires a different type of oil which contains different detergents needed to keep the engine clean
