Nice find. Most switches I was finding do not list the specs such as NO or NC and the activating pressures. If this works out I will send you a free kit!

I am also working on some options to heat the 17-19 roll over valves quicker with electric similar to the new 2020.

I would want the electric version, when the alarm goes off then what,tow the sled back and put it in the garage?were looking for something automatic i like the heated version better or the pressure relief

you open the tank, it will release the pressure and let the engine warm the valve. Or another option would be to install a inline solenoid valve that will open to atmosphere if the pressure rise in the tank.

The valve is not going to freeze up during operation. It is continually venting 165 degree + air through it. The freeze up occurs when sled is run then sits outside long enough for it to reach sub freezing temps. Once that valves cools below freezing temp, then any moisture inside is prone to freezing the plunger in place. The alarm will trigger almost instantly upon start up if the valve has froze shut.

The relief valve I have concluded is just another point of potential freeze up especially once you try to direct the exhaust from it via a hose. Lots of heat with a turbo and exhaust in that area so we can't chance spraying a an oil vapor just anywhere under the hood.

This seems to be best solution..you should not have to wait to warm up anything unless you want your friends to give you $hit about it!!!!And why is this not a recall?????it can be a fire hazard!!!!!!!!!

Switches arrived. Description says the switch is normally open, but one I got here is clearly closed with no pressure! I did get 2 so I will double check the second one.

At this point the search continues for a switch!

Newark electronics or Newark.com may have the best selection of what you are looking for.
Only takes a minute to take a peek at their pressure switches online, or you can call for specifics! Around $40 ??

Low oil pressure switch would be normally open under pressure. If you had to settle for two wire it would still be a good seller. Thanks for all you do to keep us riding!!!

Spent some time at NAPA with a multi meter going through different oil pressure switches. Found one that will work and it uses a sealed connector as well, so it will look more factory than a generic spade connector. Have Rock working on the connector to match the sensor and he said he has a source for them.

Tested the switch and it appears to be around 5psi activation. Upon start up, with the vent plugged the alarm trips within 2-3 seconds.

Good advances today on this project.

How’s the oil tank gasket coming? Are you still working on that?
