Pneumatic leak test vs. Hydrostatic leak test
Pneumatic leak test vs. Hydrostatic leak test
(OP)
Is this correct? You can justify a leak pneumatic test at a lower pressure than a leak hydro test. Because the molecular weight of the gas is lower, thereby you are able to identify a leak faster. If so how can this relationship for a nitrogen leak test vs. a diesel leak test?

If it's a sensitive leak test that you're after, then a low pressure air test with soapy water (to detect bubbles from the air) is probably your best bet.
