Review on Spectra Premium FN543 Fuel Filler by Gene Evans

The filler neck solved the long-standing problem of "checking the engine" on our Pontiac Grand Prix. There have been no "Check Engine" warnings since installation and we expect a good and long service from the part. During installation we were also warned of a gas leak that cost us a lot of money and we just assumed it was the leak. Everything is fine now, we are happy with the product and the results.
