There is a valve in there that opens and closes depending on pressure . It regulates the pressure from fuel pump. once pressure is achieved, valve in filter opens. Mine was sticking open, therefore not letting system build up pressure. Hope this helps. You can rent fuel rail filter from auto zone . its free.
That is probably the issue here, I would suggest that anyone replacing any unit purchase a leading brand. Many of these after market parts fail too soon.

I also cannot see why people insist on changing the OEM filter before it is necessary, this is a large filter and it will take a lot of crap in the filter material before it gets plugged up and fuel these days is very clean unless maybe, you frequently buy it some old gas station in the boonies. Changing an OEM filter for some cheap Chinese junk (nice pun) seems rather senseless to me.

I would sooner pay twice the price and buy a Bosch item instead of a filter that uses cheap components and filters through a recycled pair of tights.
