Air in fuel filter housing?

[laduke]

Well Im knee deep in crap Im curious how to fix air in my fuel filter housing on top the engine. If you turn the key on it fills in like 3 seconds but also alot of air going in it as well even after you turn the key off any suggestions?

Sounds to me that you have air getting in to the system previous to the filter housing if air is entering the housing along with the fuel.
The only thing I can think of that might cause that is the quick connect fittings on the lines at the HCFM. The suction side of the pump is where I would look first, since if they fail on that side, the pump would suck air in through them. Have you had them apart recently?

It's also possible that if you just got done changing your fuel filters that the primary fuel filter cap isn't seated correctly and you're sucking air there. Other than that, the secondary filter housing will self bleed whatever air is left after you put the lid on and seal the system.

yes I just recently changed filters and I havnt pulled the lines off ever I think the cap wasnt seated correctly but I have other issues which is why I changed the filters I dont register any oil pressure on my gauge and it wont start It takes about 15 20 seconds to fill the oil filter housing any help would be appreciated

Okay I think the 6mm drain plug maybe stripped out cause I cant really get it tight but I dont know if thats my only problem how do I know for sure where its pulling air?
