Low Fuel Pressure/Loose Fuel Heater ***.

I've had low fuel pressure ever since I installed my fuel pressure gauge (and who knows when it started). It varies from about 8 psi to 15 psi max.

I removed my prefilter "hoping" that it was dirty which could have been the root of my problem. It was virtually spotless. It was then that I noticed that my fuel heater assembly was loose. I haven't noticed any fuel leaking but could this looseness cause a low fuel pressure or perhaps some other problem such as allowing air into the fuel system? Does tightening the prefilter seal up the heater assembly also?

I have a new lift pump that I was going to put on but I'm wondering if I should reassemble things and see if there is any change in fuel pressure. Any thoughts?
