I need to know if anyone has a good method for installing an autometer Oil Pressure sending unit to a B16A2. The unit is 1/8" NPT while (according to Helms) the stock oil pressure switch is 1/8" BSPT. The unit is large and of course the stock switch is small (and everything is real close to the oil filter). In addition the Pressure sensor doesn't use a ground line and the guage uses an engine ground. Links and suggestions would be appreciated.
