Diesel Smell

[Tom Warner]

You will never find the leak using a sniffer on diesel fuel. The
simplest was is to use dye in the system you are trying to find a
leak in. Tracer products makes a full line of additives for this
purpose. Buy a bottle of Dye-Lite TP3700, add it to your diesel fuel
and then you can find even the smallest leak with a UV light. It
costs about $20.
