On my new engine I opted to use the blueprinted, high flow boundary oil pump.
Since that is sealed and marked from factory I didn't want to open it before I installed it.
Does anyone know if these are packed? Boundary says on their home page that it is "lubricated", but do I need to prime it before start up?

thanks.

Brand new I never had to prime a boundary pump. It had heavy grease in the pump/gear assembly which should provide enough vacuum to pull oil up on startup.

After transferring the pump the second time, I had to prime it using the 1/8npt port.

No need to prime new pumps.

What do you consider priming it? You don't need to add anything like oil to it for the first start. I would turn over the motor with the spark plugs removed and injectors unplugged until you see oil pressure. Then put in plugs and hook up injectors and actually start the motor.

IMHO it's simpler to unplug the fuel pump relay than the injectors, but same effect.

Easiest to unplug the CAS which prevents sync and leaves the coils and injectors turned off.

damn, there's nothing easier than that.

Poscats for good tips

You do get a prime pulse with that, though.

Easiest to set flood control in ms, depress the accelerator fully and leave coils off

Great! lubricated can mean so many things, I thought that I'd ask instead of getting stuck with a non-sucking pump.
Thanks.

About to re-install a Boundary pump in my engine. I will take the pump completely apart, clean it up and assemble again (thread-locking the plate bolts), new OEM seal and new OEM pressure port plug with sealant. However, I am worried it will not be able to self-prime. Should I pack it with assembly lube before putting it back together, or leave the pressure port plug off and fill it up with oil prior to startup? Anything else I should be aware of?

I pack with assembly line. I also prime pump by filling the plug with oil once the motor is in the car and everything is ready to fire.

I just installed a boundary pump a few hrs ago. There is no reason to disassemble the pump. Check the pipe plug to make sure it is tight and has sealant. Replace the seal with a factory unit. Just an FYI the factory seal that I installed was a bit odd since the outer lip which is just a dust seal did not contact the journal. After it is installed before you bolt on the pick up you can pour in a tablespoon of oil or assemble lube. The pumps do come clean and have some assembly lube so it is not really necessary to add lube.

When an engine is assembled there is enough assembly lube to allow the engine to start and prime. Priming with the starter is ok. Obviously a pre-luber is best. I always add my oils just before I start the engine. I also add it warm and add a little extra to increase the level to help facilitate priming. For me the initial oil which is usually 5-30 is only in for 10-15min.

Thanks! It has already been taken apart to clean/inspect, as it has been previously used.

Replaced the gears only in my oem old house. Just made sure there were some clearance (0,05mm) and packed it with lube. No problemos. Cleaned the over pressure cylinder with some scotch brite and added a random washer to shim it some for a higher peak pressure.
Worked fine
