99 e300 turbo diesel

i replaced all the clear plaastic lines and the shutoff valve and im aware that i'll take a while to get things going. but the question i have is that i have fuel going through all the lines except the clear line from the lil prefilter/strainer to the banjo fitting. i been cranking it for a while and i cant seem to get anything flowing in there. do i just keep cranking or did i mess someting up that i need to fix?
