Has anybody tried to use these for $25? It is indicated for use on the 7.3 but one review said its hard to get the adapter to work.

One guy said it worked another said pos, but had to use parts of it to make his 150$ work.....iirc he had to use the hf adapter.

I think his comment was it jumped over the place, but his issue was blown hg, so the other cylinders pressure would jump to the one tested giving the funky reading....
For 25 id try it, if it no worky take the sob back.

Mine works fine but the adapter that comes in the kit for 7.3 is too short so you have to make your own long enough to fit and work.

That's exactly the feedback I was looking for. Thanks. I'm without my tools and garage here so retrofitting becomes a real challenge.
