1. When did this problem start happening? After a fuel filter replacement? Some time after running biodiesel?
2. What is the condition of the fuel hose between fuel filter <==> IP?
3. Have you checked that the banjo fittings on the filter head are tight? Hose clamps? Air bleed screw?
4. Does the fuel filter have a drain valve at the bottom?
As you can see, I'm concentrating on the area around the fuel filter/filter head. Can you add a section of clear fuel hose immediately downstream of the filter? That way we could perceive better the source of air ingress.
Low pressure (<5 PSI) electric fuel pump should be OK.
No clue about any squeak after shutdown. Have you tried using a mechanics stethescope?
