As many of you know, our rig oiled the track on Sunday. It was due to a broken (vibrated & snapped) fitting for our oil pressure gauge. Paul Whittaker and Rabbie suggested I switch to a oil pressure sensor switch. I would like to know what kinds/brands people are using and how they have them hooked up.

Thanks, Doug D.

You probably want to get a higher pressure switch than the ones you get at the local parts store - ideally one that goes on just a few PSI under whatever your normal hot running pressure is. This way you have some warning that pressure is dropping - a normal 5 PSI switch is going to light up just about when you motor is seizing. Typically these switches mount using a standard pipe thread - you can get the tap at Home Depot and tap out your existing sensor port. (though you'll probably discover it's already 1/8 NPT)

You can also replace the pressure line to the gauge you have with plastic covered with braided stainless. if it's protected where it entered the engine and gauge this should be as reliable as brake lines are.

Thanks Sam, The running pressure of our 750 is like 10-15 lbs. So I might need to get a really low 5lbs. pressure light. I def. need to have a light if I plan on running with the VRRA, it's in their rules.

I also plan to re-plumb all the oil lines with braided steel with swivel ends and use all aluminum AN fittings like the race cars. I like having an actual pressure gauge on the rig. Our problem was a vibrated/snapped brass bushing, I think the switch to anodized aluminum should prevent future snapping of the fittings.
