The normal D-Jet pump has a check valve built into the pump, to keep 
gas from flowing backwards into the tank after the pump is shut off. 
The usual failure "leak" is backwards thru this check valve, so no 
external leak would be evident.

I don't know if the pump you have even HAS a check valve, so the 
decrease in pressure you see may be perfectly normal for it.
