The Pressure Gauge jumps to 44psi when pump stops pressure drops to 38psi fuel, regulator checks out good when I remove vacum line pressure increases about 5 or 6 psi. New fuel filter has surge at steady rpm or speed while driving. Would a vacum leak cause this ?

Hi,

 

A vacuum like will cause this. Check your vacuum lines by spray them one at a time with carb cleaner. when idle changes when one of the is sprayed, replace that line
