Stop Valve Replacement??

[Wreckclues]

I have an M813, not sure how many models have this part or if this post would be better served in another forum, but has anyone found a cheaper civilian replacement for this valve? The lowest OEM valve I've found is $175.
The 1/8 NPT stem on my valve is bent, doesn't line up well with the fuel line, causing potential air intrusion issues. I found an inline 6AN valve that's close. The length is 2.5 inches, but I'm not sure if that's LOA or Billet length. If LOA, with the appropriate 6AN adaptors for 1/8 NPT male stem and 1/2-20 Inverted Flare the length should be close. The pipe diameter of the 6AN is about 3/8 of an inch. Would only have to consider a redesign of the valve handle from 90 degrees to 45 degrees as in the OEM part.

I twisted mine off from over tightening so I cut off the male threads and drilled & tapped for 1/8 NPT female threads to use a nipple. If you can drill straight and tap straighter it could be a way to fix your misalignment (don't tap too deep).
