Reply To: FX Impact with upgraded gauges " WIKA" photos
You could make a shim washer to time it up… but that adds two surfaces to the pressure containment, which is why I just left mine as is.
Can you upload a side view picture of your reg gauge showing the gap (if any) between its stepped back-side and the FX cover plate?
Mine had a .032″ feeler-gauge gap when fully seated.
Regarding dial orientation…Dawned on me that FX may have a threaded gauge fixture that determines how far off the gauge face would be, which points out what thickness spacer/seal to drop in. This may account for why some WIKA gauges WILL seal, and some appear not to. Mine having a delrin seal that was thick enough to allow the WIKA gauge to fully seat without any additional fitment??? Just a guess.
