problem #3

For over the last year there have been many times that soon after starting to fill my tank, the fuel would suddenly splash back kicking off the automatic nozzle splashing fuel onto my leg the first time it happened. Fuel would be on the side of the car and onto the tire. Every time this happened it would take up to 30 minutes to fill the tank manually. Starting last month it started to occur every fill-up time.

I remembered having a somewhat similar problem on a different vehicle in the past, so assuming it was the anti-siphon at the base of the filler tube and knowing that would mean an expensive tank replacement. I tried the past solution, which was to force a stiff small diameter hose down the filler tube, past the anti-siphon. I forced it past 3 times, using a 7/16" outside diameter fiber reinforced plastic refrigerator water line that I had. I cut the hose at an angle to more easily find the anti-siphon opening. I went to the filling station and PROBLEM CURED and has not reoccurred now after about 5 more fill-ups.

The hose that I had on hand was 7/16" and barely fit so I feel that a stiff 3/8" hose would have fit in easier and would not have required as much force.

So to any other Acura MDX owner with this problem who cannot justify the cost of a new tank ( about $1000 ) I would recommend trying this easy fix.

Same issue as all the other complaints listed. Difficulty filling up the gas tank. It will overflow when it begins, it takes forever to fill up the tank. It actually started a few years ago. I was trying to find a solution when discovering this website. Based on reading all the previous complaints, it looks like replacing the entire gas tank is the only option. It looks like it is an Acura MDX 2004 issue, too bad that Acura does not have a solution at their dealerships.

I bought a 2004 Acura DMX from a private party about 2 months ago. The owner mentioned that it was difficult to fill the gas tank without the pump tripping off so I am not sure how long this has been going on. The very first time I tried to fill the tank the pump tripped off and spilled gas all over the back tire and my shoes. Now every time I try and fill the tank, after 2 seconds the pump stops. It takes me 20 minutes of constant clicking to fill the tank. No one seems to know what the issue is. Are there any suggestions?
