All 1/8" pipe fittings on the PRV are BSPT -- 28 TPI (versus 1/8" NPT -- 27 TPI). Such fittings are very easy to obtain mail order (McMaster Carr for example) but are rare over the counter. I'd recommend adding 1/8" BSPT tap & die to your American set for just such emergencies -- you could have turned down the smooth part of a 3/8" bolt to plug the sender hole. BSPT are handy for custom work too. I replaced my PCV valve (unique to my installation) with a calibrated nipple from a surplus cold start tube. Nipple threads are of course BSPT. Used my tap to modify a brass fitting to join the nipple to a larger hose barb (again, unique to my installation).
