Review on Spectra Premium FN933 Fuel Tank Filler Neck: Expert Quality for Superior Fuel System Performance by Joel Gumbiner

I ordered this part for a 2004 Trailblazer. It works, you need to connect a small hose to it as it is not used in this application. However, after installation we had to find another gas cap to install, the factory one no longer worked. I'm not happy with the quality of this product, it's very cheap and doesn't let you crank the fuel pump all the way up without turning it off. The metal is cheap and brittle, and will move a lot when you stick a fill nozzle in it. I would not recommend this product, it is rubbish and not worth saving money over a genuine ac delco part! Save your money and buy a higher quality filler neck!
