What is the size (dia., thread count, type) for the oil pressure switch? I'm trying to determine the correct adapter to attach an oil pressure gauge.
The gauge hose has a 1/4 18 NPT male end. It came with an 1/4 18 NPT female to 1/8 27 NPT male adapter to fit the other adapters (1/8 27 NPTfemale to etc). Unfortunately none of the adapters are the same as the oil pressure switch (which seems to be a 1/2 20 UNF or possibly 1/4 20 NPT will work).
