Best way to prime c15 fuel system?

So I had issues earlier in the week getting the truck started, turned out to be a wiring issue (Pete 387 with cat c15)

During that process we had issues getting the cat primed and running smoothly, eventual we got it. I noticed a radiator leak so yesterday I shut the truck didn't and pulled the radiator, got that all buttoned up.i have a spin on fuel water separator filter and don't like it so I found a good shape used Davco separator, so after the radiator I pulled the spin off set up off as tried putting the Davco on. Long story short it wouldn't fit comfortably, so I put the spin on set up back on. Now I can't get the #### thing running right.

Filled the filter full and spun it on, hit the primer pump and turned the key, it ran rough for a few minuets then died. Filled the primary filter again and died again. Third time it cranked over and I snapped a belt, so I'm done for the day, morning I'm picking up a tensioner and idler pulley as they're both grinding, and a new belt. Just curious what the fastest way to prime this bs system is.

Thanks in advance

 

Only two lines, one into the filter housing, one out, yea there correct.

I didn't know if there was a bleeder screw I could loosen, use the hand pump to pump everything full, then close it back up.

 

Exactly the response I was looking for. That's 100% doable with the shop air. As soon as it comes out, just close the bleeder back up and fire it up? Thank you

 

I could just put a small nozzle on the airline, and poke it into the vent tube and apply a small amount of pressure that way. I think that would work also.

 

I'll have to look in the morning, in not sure on either.
