WATERWICH Oil Pressure Gauge 0-150 PSI DC12V Press Gauge Meter Kit 2inches 52mm for Car Truck Vehicle Automotive

I have installed it in my car and I'm happy with the results 😊

It works. I just needed that at the time and it did that

Trabaja muy bien

Well like the old saying goes " when you buy cheap you get cheap". When I finger tighten the sensor wires to the sensor the connection post snapped off. That's what I get for going cheap.

For anyone reading - this unit itself NEEDS to be grounded. The sending wire reference reads resistance to ground for pressure. Increase resistance to ground, you read increase in pressure. If your unit reads 150 and nothing else the sending unit on your motor isn't grounded (check if it's mounted not to the engine proper, if not add a ground to chassis / engine, etc). Base resistance on mine, sending terminal port on sending unit to unit body read at 9.6 ohms, giving a reading, when grounded, to 0 on the gauge. If you remove the ground from the unit the gauge will read 150 (infinite to ground ref). Since my old truck only makes about 7-18psi oil pressure normally anyway, i increased resistance of my sending wire so the warning light wouldn't be on, and to give me a base (zero) reading of 20. I can then infer from there where my oil pressure is in conjunction with the OEM gauge. This required 33 ohms on the sending wire itself. If you're familiar with using a multimeter, soldering, etc, this is a straightforward fix but ultimately shouldn't be necessary.

Went through two of these. Crapped out pretty quick. I think the issue is the cheap senders. Do yourself a favor and run a hard line manual Guage.

Don't waste your money.
