I had the same problem and found I could order one but it was a holiday weekend coming up and I wanted it all done over the weekend. Also, the sending unit was 1/8" thread and the shrader was 1/16" thread and I could not find anywhere in town that carried 1/16 fittings period... What I ended up doing is going to the auto parts store and finding 1/8 male to 1/8 female adapter and then taking my shrader and sliding it into the male end of the adaptor (may have ground the threads down, don't remember for sure it has been a few years) then took it to work and had it brazed together. It's not the prettiest thing but it only cost me about 2 bucks. If you can't braze yourself a welding shop porbably coould or you might even try something like JB Weld. The only bad thing about it is that your shrader valve is no longer used by itself. Oh yeah if you do use this idea, make sure you remove the valve core before you put it all together or you won't ever see any pressure out to the gauge. Anyway, good luck with whatever you do. Oh, almost forgot, once I had it modified I installed a 1/8 45 fitting to angle the sending unit to give me more room at the inlet pipe.
