Works appropriately and as expected.

Works out of the box with Hondata KPro V4
Cheaper than buying a whole flex fuel kit and worked perfectly with my KPro V4 to add flex fuel capability to my K24 swapped EG

Great product
Used for a E85 conversion on my 2010 Camaro, has been holding up so far and worked well on the dyno, great for aftermarket use or OEM

Fixed GMC Sierra P0178 error
Super easy to replace. Start C with a cool engine and catalytic converters. Check online how to release fuel line pressure before removal - and be prepared to catch a lot of fuel.

Essential component of DIY flex fuel system
I coupled this sensor with a home-built arduino setup to measure the ethanol content of the E85 I'm using in my 300ZX. The sensor functions exactly as expected. I haven't been able to compare it to a known test result, but I've seen 9% reported for the E10 fuel in my area, and I'm seeing between 75% and 80% ethanol content in the E85 in my area (the spec allows something like 52%-83% ethanol) so I'm pleased with the results.

Used for E85 in Miata
Used in a 1993 Miata to run flex fuel E85 with A Speedy EFI ECU. Simple Install. I only use this car on road course tracks, but it has been working well with no issues.

Got a continental ?
Not sure I received the correct item, part number is different stanped on it.Not stamped as an ac delco either but a continental with a different part #.Going to research it and may have to return.Edit: Looks like they chanhed the part # at some time and this should be correct. I got it plumbed in my truck feed line, be a little while before I install the wiring and tuned to see if it works.
