I tried to fill up my tank two weeks ago and after about 1/2 gallon the gas started shooting out of the tank past the fill nozzle. I chalked it up to the heat wave and figured that I would try a few days later at a cooler time. It has happened every time since then, and the only way to fill it is to go about 1 gal every 3min. Also, I notice that when I unscrew the cap, the gas fumes shoot out like the tank is pressurized.

Any ideas?

Maybe a vent is plugged?

Anyone know where a vent may be - or how to unplug it or test for this theory?

Thanks!!!

is it necessary to make 3 threads? get ready to get your flame on.

 

did i pick the right one and win the prize?

 

I belive that when you open the tank on a hot day thats normal, again my car reeks of fumes so no comment, lol.

I also once had a faulty gas pump that did not stop filling the tank after it was full. Maybe your tank is full. Gas gauges gone bad, dunno just possible problems.

 

i had the same thing happen to me once, where every the gas nossle handle would not stay locked and after about 10 seconds of filling up, it would start to leak out. I just said f-ck it and didnt gas until the next day, an dthere was no problems after that at all (knock on wood). I know its a really stupid question to ask but just making sure, did you go to a different pump the next time you filled up?? I think that i just had a faulty gas pump

 

Even if the pump is faulty, the gas wont come back at you, unless it is full. Maybe the guage is broken and your really full?

I suppose if you didnt put the gas cap back on tight, it would keep the system de-pressurized but it would throw a CEL.

 

It happened multiple times on multiple days, and I am sure the tank was not full. So it is normal to spew out fumes then? It seems like when I capped a full tank - then ran it out - it formed a vacuum in the tank and sucked in.

 

RICE for makin 3 threads yo

 

total moron IBTL

 

maybe you should ask multiple questions and see if you get multiple results on your multiple stupid questions?

 

I don't find the questions stupid, and if the orginal poster accidently clicked create thread a few times big deal, the moderators will fix that. If your car isnt taking gas on a half full tank, something is wrong.

 

I would guess that you're putting cold gas into a hot tank. There's some vaporization going on which builds up a back pressure to spray the gas out the filler. Only a guess mind you.

I always thought that the gas tank was under negative pressure (partial vacuum) as the inlet manifold sucked all the fumes into the engine to burn them off (and discharge the carbon EVAP cannister)

The pumps have automatic shutoff to prevent this sort of thing so I doubt the tanks full (bad fuel gauge)

It's like feeding your kid brother, you gotta burp the b@st@rd every now and then.

....jus my 2cents worth

 

I didn't post 2X, or at least not intentionally. I did have to re log-in in the middle of the post so who knows what happened. I am sorry that was so confusing for you "ChristheNite" and "DrTySOUFMaX23". Life must have been cruel to you two...

 

So, how do we burp a maxima?

 

hit the gas tank with a hammer as hard as you can , seriously evreyone knows that...

 

check your fuel pressure.

 

do this... take a 4 foot rubber hose smaller than the flap in the gas tank and insert it into the gas tank all the way down the bottom... what u shoudl hear is a bunch of air coming out... my brother had the same problem on his cutlass..

 

i think its safe to conclude that there's something seriously wrong with your gas tank/car.

 

Bump to that.. LOL

ohh mman, evertime i look at my sig and its reminds me of goooood times with my maxima. it was sooo beatifull, now its gone FOREVA!!

 

wow, thats a pretty sick drawing of the maxima yo, is that the jdm spec?

i can tell u took many art classes
