Reddit reviews Yellow Jacket 49002 2-1/2" Gauge (Degrees F), Blue Compound, 30", 0-120 (Retard Protection to 350 psi), R-12/22/502

any specific questions I can help with? I'm not sure what happened to that photo set. The honest value was just in seeing all the different sides for understanding assembly. BUT assembly is pretty easy when you see the parts in front of ya.

I would recommend buying hoses from discount hydraulic. Use FJX-06-06 for 3/8 female JIC on your hose.

On your system, use a 3/8 FNPT tee, and put a gauge (will need bushings to adapt size), and a 3/8 NPT valve with a NPT/JIC fitting.
I would consider using an 8in or 10 inch collection chamber. Couple that with a "shatter platter" for ease of collection.

You can get custom lids from Glacier tanks these days Ensure that yours has the fittings you need, and a central dip tube

6"

8"

10" with sight glass for extra funsies

For recovery manifold, I would do something similar to the MKIII design, although I only have a gauge and recovery port (pull vac from the same place) on mine. Simple is best.

For general quality stainless fittings: www.stainlesssteelfittings.com (also carry compression fittings)

I vomited a bunch of information. Let me know if there's some basic stuff I can point you in the direction of.

And check out the WIKI. it's a work in progress, so definitely ask questions.
