This has been a bit of an adventure.. the line is definitely -6 based on the part number molded into it. But -6 JIC fittings are clearly too small.. and without taking my shocks apart it is difficult to get a positive ID. Turns out -6 SAE 45° has larger hexes.. got one of those, still not right.
So I'm narrowing it down to the line being -6 but the fittings being -8 37° JIC.
Before I bought two more fittings that may not work, I contacted King this morning. They said they should be -8 JIC (37°), but would be concerned about possible cavitation of adding a 90° forged fitting in the flow path.. those things have a very sharp angle inside.
Sure making the case for just protecting the lines..
But that doesn't play nicely with my compulsion toward problem solving.
A 45° fitting would get me the angle and position I need, and be much less restrictive to flow.
Or even better, they make the fittings in a bent-tube format for great flow characteristics, even if they are more expensive. About $25 ea, vs $8-10.
Inserting this into the line without adding significant air will be a process. King was explicit that I'd need to do a full rebuild, but I have an idea similar to what I did when I had to add oil to one line after the leak. Should save me having to remove the whole assembly.. and potentially add a very small amount of air, but that will be reduced in volume significantly once 200psi is added to the shock, and it should just find a high spot in the reservoir where it doesn't harm anything.
Anyway, when I get this part and add it I'll document all of that in a separate thread. Probably way too much work for the average person simply trying to avoid reservoir hose rub, but IMO this is the right way to address the problem for people with -50 wheels like myself.
I found it funny both Filthy and King said my wheels must be the wrong offset, they never have rub issues. Never occurred to me Rock Warriors would be considered "wrong", but then I guess the majority of people running kings go with significantly less offset for other reasons.
