    I have standard idiot lights on my gs 455. Want to add an oil gauge which means different sending unit. Can anyone recommend brand/provide part number for sending unit for a psi gauge, thanks

    I replaced the idiot light oil sending unit with Autometer sending unit + oil pressure gauge + copper tubing instead of plastic tube.

    The sender unit comes with aftermarket gauges. Are you talking about changing over to stock gauges?

    i installed EngineStat which sends temp,. volts, vac, rpm and oil status to your phone via blue tooth . but it appears that they do not tell you exact oil pressure.

    Not recommending any particular brand of gauge, but I installed a pipe "TEE" with a close (short) nipple installed on the straight across line (not on the angle leg) and used PST pipe sealant with Teflon on all thread fittings. Either way you go with an electrical gauge or true mechanical gauge. If using a true mechanical gauge, PLEASE use a copper line or stainless steel hose, not the flimsy plastic line provided. Also let it get up to temp and definitely check for even a weep leak. Protect the wiring or tubing from abrasion with appropriate measures.

    Just a word to the wise; most of the brass fittings are made from chinesium. I have a hydraulic hose guy in town that gets Parker Hannifin steel fittings for hydraulics. Brass dont get it and the close nipples are prone to cracking... JMHO ws
