Where to get Deatscheworks injector replacement O-rings?
I damaged 2 of the O-rings (long story), and factory style ones don’t seem to seal well with my Vishnu fuel rail. The factory ones are loose on the injector. The ones that came with the injectors are not.
What OE O-rings work with them?

Mike Deatsch emailed me back and said I could probably use 2002+ WRX O-rings.
Interestingly, Rockauto says "GB 8024A" which also fits "Mazda 1984-2007".
I then looked at 2000 Mazda miata and it does use the "GB 8024A" and several others, including the Felpro ES70600 miata O-rings which I tried yesterday which didn't seal.
Several other auto parts websites say the ES70600 fit the miata but not the WRX. So far no other online sites have O rings for the WRX.

It's hard to accurately measure O ring i.d. and o.d.
Instead I'll measure the diameter of the injector neck on which the Oring sits, and the Oring thickness. I reckon the Oring i.d. needs to be slightly smaller than the first number.
RC: 7.8mm, 2.25mm
94 factory: 8.0 mm, 2.0mm
Deatschwerks injectors later, they're in a shop.

Yes I did, thanks, I ended up re-using some O-rings from various miata injectors.
My problem turned out to be
1) I ham fisted them in, despite having done this 3x before, see (2) below
2) that the prototype Vishnu fuel rail (from way back in 2001), is subtly different than stock and for some reason the Deatschewerks injectors seem to be a bit fiddlier to plug them in without damaging the O rings) then RC injectors.
For posterity's sake ... my caliper battery died right when I was gonna measure the required i.d. on the Deatschwerks injectors, but it looks like 2.0 mm O-rings witih 7.6 mm i.d. will work.
These ones may work too:

For my Vishnu rail (don't know if this is true for later production or FM-sold units), the O-rings had to be snug on the injector and not loose, else they'd tend to catch on the rail while being plugged in.

I have the same rail and RC550s. the RCs have two plastic spacers that sandwich the o-ring. RC has since moved to aluminum spacers because the plastic ones eventually get loose and fall off. Imagine my frustration when I found that out upon reassembling! Thankfully they sent me the aluminum replacements.
As I recall, the o-rings weren't snug but were captured well between the spacers.
