PSA for anyone with a Boundary oil pump
First off let me say that it's nice to have a company that will build you a bulletproof pump. However, after I built my engine I noticed a small oil leak from the pump. After investigation it was the Allen head plug that seals the high pressure port. Boundary doesn't use the correct plug, and they don't use sealant. Mine was leaking. I took the OEM plug out of my old pump and it's tapered where the one boundary gives you is not. Installed the oem plug with liquid Teflon, and viola no more leak. Hope this helps someone building an engine, check this plug before you install it.

I also noticed on shibby's car that the threads felt parallel, which could keep tightening until it was recessed in the housing.
Thanks for the heads up.
@Shibby oil drops?

It'd be really weird if they shipped with a set screw instead of a tapered threaded plug. If BE keeps the stock thread size, it's actually 1/4BSPT, which may look straighter if you're comparing to a 1/4" NPT. There is such a thing as BSPP, parallel threads, but they require an O-ring to seal, so I can't imagine they'd even make BSPP plugs.

I have a question while this post is about the plug. I got my Boundary oil pump and I was cranking the motor to get oil pressure prior to the first startup and I received none! I looked at my oil filter, no oil. I looked at my pump and the screw or "plug" is threaded down in the pump a good amount. I'd say probable close to half an inch. I was wondering if this plug prevents oil from traveling down the channel or what. Could this be why I have no oil pressure? If so PLEASE leave a reply. If all I have to do to get oil pressure is loosen a screw, I will be so happy. Thanks
