I found the O-ring that's most likely the root cause of a slow leak from the front reg I've been dealing with for weeks now. Problem is, it doesn't show up on FX's parts diagrams. Does anyone know which O-ring this is?
Thanks! That O-ring is supposed to be 7.5x1.5, measuring something squishy with calipers is damn near impossible so you were really close.
Another O-ring altogether ended up being the culprit. It's the little 4x1.5 one hidden deep in the reg body, also not included on the diagram (ffs FX, how hard is it really?). Replaced that one and leak seems to be fixed now.
I believe that my Excel spreadsheet includes that O-Ring information. It's on tab labeled "Schem X x Pg 4", far lower right corner of the opening spreadsheet. There are a total of 13 Tabs along the bottom, each with a different parts section that is shown on Tab "Schem Pg 1". Some folks can't open the spreadsheet for some reason, perhaps because it's Microsoft Excel?
