QUOTE(wonkipop @ Nov 11 2025, 01:53 PM)  .. the fuel filter you still have under the engine shelf could be a problem. is it a high flow pressurized filter you have fitted there? they are larger diam metal cylinders. it is essential that it is one of those in the configuration you are describing you have. if its high flow it should be fine. standard type filter location would only be fit for purpose between tank and pump up front. must be before the pump. I've got a CarQuest 86012 under the engine shelf in the rear. It'a a metal can filter unit but I see no mention of high flow or being pressurize. Though I was getting 28-29psi before the regulator.

The FP is an Airtex 8445 iirc , perhaps it’s an intermittent issue with this particular unit.
