If Acura wont cover it from what you tried, might as well find a regular repair shop to do it or sell it.

I have this problem on my '01, as well. I am just very careful when filling. Let it fill fast up until around 12-13 gallons, slow it down to a crawl until it clicks. Works every time.

so you have problem now or not? as for last 2 yrs i am having problem every 0.2 - 0.3 gallons pump shuts off so I have ti fill gas manually.

I have only experienced that problem one time. My main problem is that when I let the pump click to turn off, it doesn't do so and I end up with 1/2 a gallon of gas on the ground. It's manageable, though, by the method I listed.

My 2004 Acura MDX isn’t taking gas. I must have typed that in google search 100 times. I had the same issue as many others who would try to fill up the car, but the pump would click off right away. You try again and the same thing!!! You literally cannot put more than 50 cents a pop into the tank without the nozzle clicking off. It would usually take 15 minutes or more to fill up the tank. I tried holding the nozzles at all different angles and there was no difference. All the local Acura and Honda service centers hadn’t heard of an issue like this before and there were a lot of dead end ideas online. Then after dozens of hours online trying to find a solution that didn’t require any sort of major overhaul, (dropping the gas tank, replacing the charcoal canister etc) I found a ‘one liner’ post somewhere about a small amount of gas mysteriously ending up in the vent line upon filling the tank. On the Acura MDX (& Honda Pilots), there are two vent lines that follow the fuel filler neck down the back driver side of the vehicle behind the tire that take a 90 degree turn at some sort of elbow coupling. Just like the other guy recommended, I removed the larger of the two vent tubes from the 90 degree elbow, and sure enough, about a ½ cup of gas spilled out onto the floor. Once the tube was empty, I put it back on the 90 degree elbow, put the clamp back on and took off to the gas station. It filled up like a charm. Before you take the car into the shop or to the dealer, you really should spend the 15 minutes it takes to take off the back tire and pull this tube to make sure there isn’t any gas in there. Very easy to do!

Interestingly enough, I have the exact same problem on my 2004 Honda Pilot. I was searching google and found this thread. The schematic on page 3 of the Acura fuel tank is exactly the same as on my pilot, right down to part numbers.

I know this is a very old thread, but was hoping someone who had a fix done can confirm whether it is still fixed.

I saw 2 possible solutions.
First was canister shut valve being replaced
Second was anti siphon flap in fuel tank

Did either fix or both, solve problem? It is driving me crazy to have to spend 15 minutes refueling. On another note, Honda USA took no ownership of issue. Claimed no one has reported it.

Thanks.
