Seems like heavy breathing keeps people from reading actually

It is clearly stated that she forced 6 gallon in the tank. The pump kept shutting off when she did that. So the conclusion that the tank was full in the beginning must be wrong

It's a good idea to pull the pump assembly no doubt but there's something wrong when the pump keeps shutting off.



QUOTE=Meiogirl;12027278]I went on a run today. The gauge went from 3/4 to 1/8 in about ten minutes. I found the closest gas station.

When I went to fill up the car, the pump kept shutting off as if it was full. I was able to get about 6 gallons in there. The gauge stayed at 1/8.

Stopped 30 miles later at another gas station, the pump also kept shutting off as if it was full and I only forced about 2 gallons. The gauge stayed at 1/8.

I've been premixing with Castor 927 4-8oz per fill up 8k miles ago after a rebuild.

Any ideas? I'm looking around online and I don't see symptoms quite like these.[/QUOTE]

Double fail.

Let me break this down for you.

FD gas tank is 20 gallons. 75% of 20 gallons (3/4) is 15. Knowing that the fuel gauges in these aren't SUPER accurate, let's give it a plus or minus 1. She then goes to a gas station because some how her FD begins drinking 1 gallon of gas a minute. She goes to a gas station and pumps 6 gallons into her tank. She has now gone from probably 14 gallons plus 6 to now...MY WORD...20 gallons. A full tank. She drives 30 additional miles. The average RX7 gets roughly 17MPG. Let's average this out again as she has now stopped to put MOAR gas in it. 17mpg will drink about 2 gallons in 34 miles. Man this is starting to sound like a full tank to me. How much did she put in the second fill? Oh that's right....2 gallons.

The float sensor is malfunctioning.

On a scale of one to even on this thread...I just can't.

Matt

tripple fail?? :-)

Dude you're right about the float sensor. It's propably faulty.

BUT she started with a tank with 15 gallons in it!
She then tried to fill it up and the pump kept shutting off. Did it keep shutting off because it was full? No, because if it was full how could she possibly force 6 gallons in it?
So there must be a problem in addition to that float sensor. Fuel tank vent valve? That's why she wrote that the car wouldn't take gas.

Off course the tank was full after she forced 6+2 gallons in it. That's not what I was arguing about.

Got it now?

I have had pumps that would mess up while pumping. Take a little then stop take a little and stop. Gets frustrating. Leave go to another station and fill it up the rest of the way no problem. So pumps can do that and not be anything wrong with the tank. Op any news with the shop working on your car?
It so sounds like the float that measures is messed up get that fixxed then check your other problem if it still exists.

We've beat this horse to death. The OP obviously knows more than any of us what she has checked and verified along the way, so lets assume it is the vapor valves which are faulty. Does anybody know where she can get replacements? We're all great, we're all wise ... let's all give ourselves props ..., but let's help her with the original question. It can certainly be the valves.

Well it turned out to be the vent vapor valve for why the tank was not allowing the pumps to work. The fuel pump sender as to why the Fuel gauge is broken. I had to order that vent vapor Thursday nightovenighted for a track weekend.

Atkins has seven left.

You know the repeated comments insulting my intelligence as the whether or not I can tell what a full freakingtank is terrible.
If you can't contribute a new solution to a post, don't. People are trying to up their post count with misguided and incorrect information?

Troubleshooting 101, isolate the variables starting with the probable. Don't think anyone was insulting your intelligence since it didn't seem like the probable was ruled out.

Glad you got it sorted

I disagree. I think some of the people that posted were assuming that she didnt know what she was talking about because she's a girl. Doing that was sexist, and just plain wrong!!!

Glad you got the problems solved.

As far as I can tell, you were treated just like anyone else on this form. You posted your symptoms and we speculated as to what the true problem was. We have your shops word as to what it really was. And remember it was YOU who posted up with the sarcastic "sighs". Nobody insulted your intelligence. We contributed, you just didn't appreciate it. That's never been a guarantee here, but regardless glad your problem is solved too.

You can't rationally look back on anything that was posted in this thread and call it "sexist". The assumptions that were made, which essentially doubted the diagnosis she'd been given and discussed easy and proper logical steps to route out the problem, would have been made if she was a 6'5" linebacker.

In the future, if you do what I first suggested about bringing the pump to the edge of the filler tube to "top-off" the fuel level would have answered your question. You would have known quickly and easily if the tank was actually full.

That's all.

I am not sure about the sexist part.


The problem was solved quickly by a ex FD owner on a facebook group thread within 1/2 day. I went to the shop, which does spec miatas, I gave them the part number, he verfied the issue. Thats when I came back on here to record my solution and figure out who sells these parts other than Atkins, and it was just more about the silly fullness level of the tank. I shouldn't have to justify myself to anybody. I guess people that know me trust my judgement and my word. Help me find a solution not add to banter. That IS being ridiculous and insulting, that's why I sighed.

I did do that when I very first observed the problem. That why this post says...car won't take fuel and I kept saying the car is not full.

Frankly you got a lot more attention than most members would. From lots of legacy members too! Wow, wonder why that might be....
I'm sorry nobody here spitballed your problem right. Maybe next time you post more information and methods, instead of leaving people guessing about what you've confirmed.
Glad you got it sorted out, interesting problem.

FYI for those that "think" it was a bad gas station pump or nozzel, If before filling up your tank, instead of inserting the nozzel the normal way, flip it 180* and fill your tank with the nozzel upside down. That way the fuel vapors coming back through the filler neck won't shut the tank of because the sensor in the nozzel is on the other(top) side.

BE WARNED!!!! If you do that the pump will NOT automatically shut off so you better know how much to put in your tank.

It's a common issue with Ford where a spider builds a nest in the vent line and blocks the flow. In turn, instead of fuel vapors leaving the vent tube, they come back out the filler neck. It causes the pump to constantly shut off while filling.

Well adamc has know me from my first FD. I was on this forum a lot when I had that car and lived in St Louis.

I used to have over 1900 posts here, but when the forum traded hands everyone got wiped. With this second FD I lived in LA and went and talked to many people, didnt need the board.

Now I'm back to the midwest, and no shops. Thus back to the internet. I have been here in this community and know many people personally.

I will tell you back then I got more sound advice.

BTWI gave the exact same information I gave the other facebook thread. Here again having to justify myself, oh my. LOL

Anyhow I would rather perhaps a moderator remove all the jibber jabber, including mine and just leave the relevant posts so that when someone else has this rare issue, they know how to fix it.
