Does it come with the plugs for the ports? Asking since I'm going to bench bleed it prior to install

I bought this MC a year ago. Mine did not come with the plugs. What I did was go to autozone (maybe it was oreilly's, can't remember) and bought a brake bleed set. In fact, I repurposed a vacuum brake bleed (hand pump style), and used it as both the pre-install bench bleed, but also once installed used the same vacuum brake bleed to forcibly draw out all the air in the lines, which is going to happen anyway once you crack open the hydraulic lines to install the MC. It really is the best way to do it. The old two person pumping the brakes and turning the brake line bolts aren't very precise. On the other hand, you get really good results by using a vacuum pump... just get the vacuum pump with the clear vinyl lines ....it helps to see the bubbles and see when they stop! also key: do NOT use a metal screwdriver when depressing the MC piston...It's very easy to score the inside travel body..not good...I use a wood dowel, wrapped in old cotton rag.....AND go SLOW!!!...and for this "two stage" MC, you only depress about 1 inch. DO NOT bottom it out. The piston can damage the rear seal. Read the instructions. My kit has the instructions clear in this.
