New Stage 2 Boundary Oil Pump - Rough Shape
#23
Here's pics of mine still sealed in the bag. I'll point out the third picture I zoomed in a bit to show you the edge burr from the milling process. I can't say it's indicative of Boundary Engineering and any "touch up" of the mating surface but it's be highly unusual for the OEM to let that go.
I'll deburr it when I unseal it and as it's on an outside edge it wouldn't impact performance but it isn't something FAB9 would have impact on. It's also very likely that the pump was shipped to me by a wholesaler and not FAB9 itself.
If you decide to surface it yourself, make sure you take care to plug the crank bore and any other ports to keep any aluminum chips out of the pump or you won't like what happens.

Yup, that looks similar to mine, thought I've got plenty on the inside edges as well. Thanks for taking the time to send.
To clarify, my pump did come with the O-ring already installed but no other gaskets for the mating surfaces, and from what I'm reading here that's not unusual. Any thoughts on picking up a paper gasket from Autozone or elsewhere and using with this? I'd feel better about the sealing ability of this jagged thing with a gasket.

this the o ring. (taken from my build thread)

I'm beating my own thread to death now but I should include this by way of follow up: I just got a call from Bryan at Fab9 in response to an email I sent an hour ago. He offered to take the pump back and ship another ASAP, or refund my $. He told me that because Boundary is pounding these out so quickly in response to demand, they aren't shipping them with paperwork. He got the SN from the pump from me and is having Boundary email me the pump's specs & documentation. He also told me that Boundary isn't shipping them with O-rings anymore because builders are sourcing their own most of the time anyway. As for the quality of the shipping itself, he owned it, offered to refund or replace. I opted to hang on to this one.

It's possible to take out the high spots with a stone but at that point you're taking on the responsibility for it working or not. Get some dykem so when you stone it you don't take anymore off than you need. And remember to plug up everything.

Not such good luck this time with Fab9, and these posts don't encourage further experimentation with them.

If it's faced flat, then it's old and should come with a gasket.
If I recall, all the newer pumps superceded the old ones and are rtv sealed. Vvt pumps are desirable for any application. Non vvt pumps are not desirable for vvt motors.

I've also had good experience with other vendors here.

Just saw these post. I have not done any business with Fab 9 , so I have no complaints. I bought a stage 2 BE pump from a member on here a couple of weeks ago. It looks pretty much the same in some places. I just happened to talk to him today and asked if the pump had been used. He said no. It was still sealed in the bag, He is a long time member here and I believe him. I think this is just the way Boundary is shipping them right now.

If it has a machined groove, around the block interface and an oring around the outlet, then it's made for rtv.
