Well what an afternoon.... tested the car again as we have foam filled the tank and lowered the pickup point of the fuel pump (was 30mm from the bottom after fitting the walbro) to try and solve the new surge issue. Went out with 1/4 tank the same problem then went out with 3/4 tank same again..!! Also the fuel pump was really noisey after a couple of minutes....
Pump housing out again and we took the filter sock off... loads of s**t and crap in the gause of the fuel pump its self..
How has it got through the sock which is micro fine and then stuck in the actual fuel pump gause ??? very strange. Anyone....
Cleaned it all out and put a new in line fuel filter in (cut the old out out to see if this had broken down but nothing major looked OK) tested again with 1/3 tank no surge at all..! Barp barp barp
Fingers crossed mix of cleaning everything up, foam and lower pick up have sorted the job. Fuel pump seems very smooth and quiet and most importantly no fuel pressure movement or alarms on my fancy STACK dial.!
