alot of air entering my secondary

Okay heres what I have come up with I did the check to see if I was getting combustion gasses leaking past one of my injectors that was a no go. So I dont have any leaks that seem evident past my pump so I'm assuming its sucking air from the tank to the pump am I correct? It seems as if my steel 6mm drain plug doesnt get tight all the way and I've tried taking the cover off about 5 times to see if it was seating wrong dont think thats it does anybody know if you have to replace the pump if the drain plug doesnt get very tight I checked the treads on the plug they look good and I looked into the pump and It looks like 1 big thread should there be more threads? Also is there some sort of test for the lines to see if they are leaking?

The fittings on the lines to the tank are really tight absolutly no play but at the hcfm they go in and out alittle maybe 1/8 of an inch. Do you thing I could be getting air through the fittings at the hcfm and if so its only about a foot long and goes to steel lines back to the tank so can I take fuel line with clamps instead of getting all new lines?

I do believe you can buy a cover and it will come with a new plug. an 1/8 of play seems a little much, could be wrong though. I would try the new cover and plug from ford.

At one time there was a kit to replace the clips and o-rings on the fuel line connectors.
Do not know if it is still available tho.
