Guardian Generac 7Kw Whole House Backup Generator
Number of Items: 1
I purchased this product to replace a bad oil sending unit in my whole house 7 kW Guardian Generac Generator system. I found it to be identical if not a good quality replacement part and it was easily replaced by me and functioned fine without any complications. I would recommend this product to anyone with a single lead oil sensor. ... show more

It may be and OEM, not sure about that, but fit and worked perfectly.

Worked and fit perfectly. My old one had failed, leaking oil. I put this new one in and it works perfectly and has no leaks.

Exact fit for my old Generac
Number of Items: 1
My previous switch failed for an older Generac 13,000 watt surge, 7,500 watt running generator. This switch was reasonably priced (not much to it actually) and delivery was decent time. Looks identical to the old switch. I had to disconnect the old switch when I needed the generator for this hurricane season, with three power outages. I had a bit of a difficult time locating the part number but finally found this one and it was a perfect fit. I used teflon tape around the threads. No leaks and generator now runs fine. ... show more

Good backup
Number of Items: 1
My neighbors Generac generator quit running. A diag revealed a failed oil pressure switch. (You can disable the switch, but that comes with the risk of seizing your engine.) I installed the new switch and everything runs like a top. He even got an oil change with the install.
