Bleeding oil system on 96 Challenger help

[Bmedlin85]

I finally got the engine back in the boat and it fires up instantly... Now I am having an issue with the oil system. I replaced all of the oil line and replaced the oil pump. The seadoo manual states to remove the bleeder screw from the pump to bleed any air out so that the line from the oil tank to the pump is full of oil. I removed the screw and the line would not fill with oil. I even manually held the pump open and still not much oil coming from the tank. I could get the line about have way full but that is it. It seems the fittings on the tank may be an issue because it is pretty loose and when I pushed it at at angle the line filled with oil.
Now I am not getting much oil to the injector lines. The seadoo manual states the if the lines do not fill with oil start the engine on a hose and run until the lines are full. I have an issue with this because that means the engine is not getting oil. I removed the spark plugs just to spin the motor over to try to fill the lines that way. After a while of spinning the motor with the pump manually opened the lines are only have way full of oil. I do not want to spin the motor much more since no oil is coming from the injectors.
Am I missing something or could I possibly have a bad pump? And if I had a bad pump would any oil at all get into the lines.
Thanks in advance for any advice.

Im no expert but i cleaned my oil tank on my 97 challenger and replaced the oil filters ,i had the same problem as you and i ended up taking the oil line off the pump till it filled completely then pinched it halfway and attached it to the pump. Yes a bit of a mess but i just got impatient waiting for the oil and gravity.
I did find out the hard way after zip ties installed and all that it would be faster if i primed the new oil filters.The fitting in the oil tank is raised and there about half of inch of oil at the bottom that sits there because the fitting is so high, i had to fill my oil tank almost halfway for it to fill the hoses a bit faster.

After all that and changing oil lines , i found all the oil on the ground the next morning because i had a leak on the side of one of the motors that i could not see and didn't know about lol

Thanks for the response. I was thinking that the fitting in the tank may have been an issue. I will fill the tank up more and see if that helps any. Plus it appears the previous owner replaced the fitting so there is no telling how high it sticks up.
Did you have any issues with filling the smaller injector lines?
Thanks again

I replaced mine and i did compare both seals new and old and they were the same height. Like i said before i did the same thing with all the lines , disconnected all of them and let them fill up pinched them connected and started with the next one.

Remove the cap from the oil tank to see if you have an issue with it venting, did you reuse the old plastic drive shaft for the oil pump?

I may have to try that. Thanks

I removed the cap and didn't really see a difference. When I bought a new stator and cover it came with a pump and drive shaft, so I am using that.

Thanks

Going forward, after you get the supply line purged of air and full of oil stop at that point, ground your plug wires and fog the motor through the carbs with a heavy dose of fogging oil as you roll them over a little bit. That will get everything that matters covered in a nice layer of oil and you can get everything hooked back up on the pump and do some more testing without the risk of damage.

From there, you can hold the throttle open and crank the engine for a few seconds and you should see oil in the injection lines pretty much right away if the pump is working.

I ended up replacing the straight fitting to the oil tank and fill the tank to about 1/2 full. That seemed to do the trick.

Thanks again
