This filter is very compact and with a 90-degree port it was a great fit for the confined space and twisting fuel line route on my 1982 Yamaha Vision XZ550RJ. The Vision was not produced with a stock fuel filter, just a screen attached to the petcock inside the fuel tank. These screens do not catch the smaller debris that clog fuel systems. Aftermarket in-line filter choices that would fit this particular application are rare. This product, because of it's small size and shape provided an easy solution to keep my carburetor clean.
I had a little rust in my gas tank that I wanted to keep out of the carb on my old Yamaha XT225. There isn't much space between the petcock and the carb -- This 90 degree filter was a perfect fit. I cut my fuel line in half and spliced in the filter in less that 2 minutes flat. It is smaller than most of the others I have seen. It has an arrow on it that shows the direction for installation. Nicely priced as well, and it works!
No other filter will fit my GasGas off-road bikes as well as this one. The 90 degree angle design eliminates any kinking of the fuel line between the petcock and the carburetor. Never run your bike without a fuel filter.
