Best way to prime c15 fuel system?

Theres a check valve between the secondary filter housing and line going to the head(allen screw behind the bleeder screw), but bingo about the rest.

 

Here we go. The problem is bigger than I thought.
You will have to pressurize the tank to get fuel up to the primary filter.
Priming of the remaining system is still necessary after that. Do like suggested before.

 

So the pressure regulator is at the secondary housing?

 

No presure reg is in the primary filter on the engine. Secondary is the water seperator on the frame rail .

 

Don't you have the two confused? I have a 1r-0749 on the motor. My primary is a Davco on the frame rail.

 

I think the confusion may be in the definition of "primary " and "secondary".
I think some define "primary" as the "main" filter which is on the engine block.
Others, like me, define "primary" as the "first filter the fuel goes through".
Therefore, using that definition, the "secondary" filter would be the one on the block.

 

Yes I define primary as the main filter the engine comes with .
And secondary as the the filter the oem adds onto the frame rail .
