Another Satisfying Purchase
Would recommend this product. Worked perfectly. Eliminated fuel leak and *gas cap" dashboard warning light. The part was a little shorter than the original, but the fuel filler hose(s) had enough play to connect fine. Installation video was spot on. The ends of the connection tubes on mine were rusted so badly, they broke off inside the filler hose on removal. Had to crush the ends of the filler hoses with pliers to remove rusted-out ends. Cannot beat 1A Autos price, fast delivery, and value. And love the installation videos. Thanks.

Fuel filler neck

Fuel problem fix.
Filler neck arrived fast. It was a perfect fit and is working great. Took a little longer than expected to install only because the old one was in such bad shape. Have never had any problem with products bought through 1A AUTO. Will continue to be a repeat customer.

Perfect fit and affordable
Like 1Aauto. The product was a perfect fit and affordable. The instructional video was a great help for a new car DYIer. Recommend this product and 1Aauto to anyone who is in need of car repairs.

Perfect fit, great price, fast delivery
What can i say, 1AAuto.com does it again. Its not easy to find parts for vehicles over 15 years old, but its great knowing that you can count on for those hard to find parts. Not only was it in stock, not only was it on my doorstep in 2 days, but it was 1/3 of the price for the same part from multiplelocal brick and mortars. It went on without a problem and actually sits in the exact OEM configuration from 17 years ago. Great job 1AAuto.com, youre definitely tops on my list for online parts.

Nicely done, the whole thing.
The rep was quick and got the order filled fast. The filler neck part came when they said it would on the correct day, and my mechanic was very impressed with the price $40.95. (Implying, the place he was going to was a ripoff, like many car repair places and the work/jobs.) This was my first experience. Definitely give it a try. Rick

Right part every time.
This fill neck fit right on at a very great price all the parts I buy from 1 A Auto are just as good as OE or better never have a problem great place to buy from.

Great Service,Right Part,Perfect Video
Once the part arrived, everything went so smoothly. The part cost a fraction of what the dealer wanted plus the installation video was right on, along with the problems that you might encounter (which I did) with the appropriate solution to the problem. I am extremely pleased with 1AAuto.
December 20, 2018
I priced this part at the usual places.... They were 100.00 more? Unbelievable! Saved me a ton of my money and part was top quality. No issues what so ever! I will be using 1A Auto from now on!
