You probably have a small leak in line letting air in, they often will leak air in without leaking fuel out. :c:

i had a leak at my fuel filter housing at the return, which was causing a similiar problem but it was more of an overnight time frame issue.

You guys need to go back to the books. Let it sit for a while, don't try n fire it up n see if there's any prime at the LP the diaghram in them often goes bad n will drain fuel back to the tank.

I went and tried to prime it manually at the lift pump and the pump ran out of fuel and there wasnt anything left to pump...
