Worked great on 88 Trans Am with 60psi
My factory oil pressure switch failed so I went to purchase a replacement, this worked great for my 60psi Digital Dash gauge. Note: For those of you with an 88 or older Camaro/Firebird (Corvette too I think), it will be below the distributor on the back of the engine. If you have an 89+ it will be part of the switch that is next to the oil filter.

Great fit. Works good so far (a month or so...)
Seems to be working just as it’s supposed to. I like the location of the nut vs the older part version. Easier to install than the older version.

As described
Put this on my sbc airboat. It's big and ugly, only saying that because it's very visual on a sbc sitting on an airboat. But it was cheap and works fine, no issues

Average quality from China
Not identical to my oe sending unit in my 87 442, but close. Pressures read higher than actual. It took 3 weeks to get it. I'm leaving it in place for now but may put one of a couple different used ones I have. My reason for swapping it originally was because my needly was slightly jerky. It still is and my rally pack has been gone through... as I said, average product.

Worked perfectly
I bought an old truck and I think someone stuck in a 0-80 psi sender, but a 0-60 psi is required with the stock gauge. This worked perfectly and I now have an accurate gauge!

Factory gauge started reading frighteningly low hot oil pressure (on a new rebuild at that). Mechanical gauge confirmed ~15 PSI when the factory sender and dash gauge were delivering/showing basically nil. The new sender fixed the issue at the dash. May read slightly higher than true but good accuracy at the low end, which is what I was after. Lest the title of this review be misinterpreted: this unit is for operational peace of mind; use a mechanical gauge if you're troubleshooting a low oil pressure problem.
