Anyone put an oil pressure gauge on their 617? If so, where did you install the sender. Mechanical or electrical? I want to put one in the smaller hole between the two main gauges and Im looking at VDO units. It'd be nice to have one with a warning light in case pressure drops and you arent looking but I dont see anything yet.
Yeah, that's exactly the trade-off that others have debated here. I like to know how my OP is doing, but it's WAY more important to know that it just dropped below acceptable limits, which a light does well.
My 606 will use the original light, possibly with a sender teed in. On my 617, I pulled the original pressure switch and replaced it with a sender from a sedan. I bought a VDO gauge that is nearly identical to the original gauge diameter and very similar style. I have not found an OP gauge that has a light built in - great idea though.
I'm sure that sender would work fine - though a genuine VDO unit would be about $1 at a wrecker. I think this is the gauge I bought: http://www.egauges.com/ProductDetails.asp?ProductCode=350-065 It's installed in a panel I made for 3 gauges and a couple of USB ports, so the photo wouldn't really show what you want. The tach position you're suggesting would be slick.
