Did you say you have a prefilter? If it has a glass bowl? Is it full? Sounds like you have air in the system somewhere. Take the delivery hose off (the one between the OEM filter and the common rail) put it into a glass jar and pump the primer again to purge any air, probably in the prefilter. After purging reconnect the hose and pump the primer again til it goes hard.
Pity you used that oil pump, if you used it after the OEM filter you may introduce some contamination. Never do this, use the primer on the OEM filter.
Otherwise it may be the oring on the filter leaking ( sucking air)
