Compression test adapter

Hello All. I need to test the Compression on my 1997 f150 4.6l

I would like to know if anyone can recomend an adapter or a kit that comes with the appropriate 14mm adapter in it or separately.

I do not wish to rent one I wish to own my own. Please list the Brand and part number so I can buy one.
Please do not say harbor fright they do not fit. Not looking for SNAP-ON or other very high end but anything else would be great. it just need to work and fit correctly.

The OTC 5603 might also work if OP can use an I/M style quick connect. However the rigid tube design may be a PITA on the rear cylinders near the cowl/firewall:

Good catch - it looks like the flexy one is for the 16mm threads and your '97 is M14x1.25

Honestly I think you'd get by with an inexpensive OEMTools:
