200 EFI all new parts, still no oil to engine reservoir

[The Godfather]

Hey guy's I was wondering if someone could help me with this. With the engine running, I get no oil to the new engine mounted reservoir, I also installed a new check valve at engine block. If I remove the line going to the engine check valve and preasurize that line, it will push oil to the engine reservoir but I can hear the air bleading off at the boat mounted tank. Shouldn't it preasruize and hold that preasure? just like a hand held sprayer? I look at it as the same type of system. Any help is very much appreciated!

posted in wrong area. Sorry about that.

Sounds like I'd find where that leak is coming from at the tank. I don't think the motor produces that much pressure to push the oil to the tank, so if you have any air leak at all it's not going to push the oil to the engine mounted tank.

Locate the leak at the remote tank. DO NOT use compressed air... 6 psi max (gearcase pressure tester or bicycle pump).
