Correct, I am alone. I already have a one man bleeder. I have this exact model:

It doesn't mention a check valve anywhere, but how could this work without a check valve? I use it all the times on my brakes and it seems to work good. If I was to use this, I would just bleed the system normally?

Can I leave the teflon on the bleeder afterwards? Won't brake fluid eat it?

I saw in my Hanes manual the eccentric adjustment you are mentioning. However, one of the drawings has it and the other don't have it. From the info I can gather, it was 1984 only... There is no eccentric on my car. I cannot adjust the MC rod.
