Sounds like you have a problem with a fuel leak from the filter housing combined with faulty lift pump operation?

Do a search on google for "6.5 diesel lift pump test".
Perform the test and report back for further diagnosis.

to test the lift pump just hook it straight to battery, mine was giving me trouble and thats how i checked. if it worksyou will hear it. if it doesnt you cant.
