Good product. Good price.
works perfect. i installed in the frame of my kubota bx24 after having the filters freeze in cold weather. the stock filters had no way to drain water from the fuel. I can now access without having to crawl under the tractor.

High Quality
I’ve got this same filter on 4 of my boats. It’s very durable and zero issues. It’s as good as a Racor filter that cost 150.00 more. I highly recommend

Great product, perfect fit
This filter is the prefect size for filtering the fuel from my slip tank to my standard tank. Was able to mount it to a bed rail under the bed with two Rivet nuts and two 5/16 bolts.

Works great don’t use provided teph. tape
The Teflon tape provided dose not work for gasoline. Great unit but use tape specifically for gasoline applications

works perfectly!
if you have water in your gas cans and pour it into the fuel tank of the mower or other vehicle, this filter will decant it into the clear bowl where it can be easily removed by turning one valve open to capture it in a bowl or bottle or let it run onto the ground. excellent product and well constructed. easy to mount.

Leaked Air; Cheap quality.
Leaks. Mounted in our boat; new hose and oeticker clamps. Couldn't get consistent fuel pressure at the primer bulb. Took a while, but figured out the filter was leaking air around the rim at the connection point. For the time and effort skip this and get the Racor, or at very least a Sierra.
