1I do not care for this adaptor, but it is the best one out there that I know of for the 12mmx1.5-to-1/8" NPT size; there are nice steel 12mmx1.5-to-1/4" NPT adaptors, but this would make the assembly excessively large. The problem with this adaptor is the unconstrained o-ring:  it does not allow a tight seal and bulges and leaks under pressure. Here's a pic of the R7962. To get by this problem, I epoxied an SAE grade-8 washer to the underside and then used an aluminum crush washer for the seal; I used a grade-8 washer for strength and the tight fit over the threads of the adaptor. If anyone finds a viable alternative, please let me know. Note: One gauge panel buyer discovered that the R7962 is being discontinued next year. That will leave the number of viable adapters at zero. To get around this roadblock, I can make an aluminum adaptor which would allow the use of the sender along with either the 1/8" NPT idiot light switch or the stock 12mmx1.5 idiot light switch; this piece will consist of an AL-2024 aluminum alloy distribution block (~1"x1"x2"), a banjo bolt, and seal rings; this piece will run $35. You should NEVER use one of the adapters made by Equus -- I had two break during an installation attempt!
2To install a pressure gauge sender/line while maintaining dashboard "idiot light" function, a tee must be used. The 9171K31 tee has one male port (which goes into the 12mmx1.5-to-1/8" NPT adaptor) and two female ports (one for the idiot light switch and one for the sender/line).
3Any 1/8" NPT oil pressure idiot light switch should work fine. I used one with a ~2" overall length and a blade terminal connection. The switch was a spare just lying around, so I don't know the original application.
4Required for mechanical pressure gauges only. While the gauges do come with fittings and a line kit, it's nylon tubing which is not nearly as sturdy and reliable as AN fittings and hose. I'm partial to Earl's, but Aeroquip and Russell are viable alternatives. You can also have hose assemblies made locally at a hydraulic supply house; these assemblies will likely be Aeroquip or Gates.
5Use either the straight or the 45°; with my hose routing, the 45° allowed a loop for hose flexure during engine movement.
