reset fuel trims; lasted about 60 miles or about an hour

It looks like the black seal is incompatible with fitting this on. Pull that out and see if it threads on. Bonus it will release the fuel pressure if the bar works to press the Schrader button. (Have shop towel handy not a lot comes out if the engine is stopped).

If that works, Teflon to seal at the threads vs. the edge of the valve.

Actually, that fitting is #11, not #4. I didn't pay attention when I glanced at the list. I just chose that one as an example of a valve depressor. That adapter is 7/16"-20 UNF on both ends. No other fitting in the kit has a depressor bar (except the main hose on the gauge, also too large for the Schrader). #11 also fits to the hose attached to the gauge, not to the Schrader, but it is a right-angle adapter.

andrewwynn, can YOU tell me what adapter size/thread works for you?
