Fuel starvation, who else?

phunk · 08-05-2011, 05:36 PM

why would they be dropping the gas tank? You have to remove way too much to do that, i wouldnt even want the dealer doing that to my car. Ill put it this way, when there was a recall on a part and dealers had to remove the gas tanks from 350z, cars were falling off the lifts forwards because they were removing so much weight from the back of the car and had not taken enough care to balance the car for that.

you have to remove everything under the rear half of the car. everything. entire suspension and crossmember and differential and driveshaft and exhaust, etc.

Good to know, hope they know the trick of getting it from the rear parcel shelf. I have something rolling around in my gas tank, got to fish it out and fix it!

Just read the manual, they do tell you about the access hole at the top. I think they will try to grab whatever it is from the top first and then see what broke inside.

phunk · 08-05-2011, 07:51 PM

ok ya they would definiately know about the access port, every nissan (and almost every car) has had that for decades. i thought you meant they were going to remove it no matter what to either replace it or something like that... but if its just something loose in there then there is no point to removing the tank because they can access the only 2 openings from inside the car anyway.

Theres a couple things I can think of that could possibly break off inside the tank. Let me know what they find!

cossie1600 · 08-05-2011, 07:56 PM

I was relaying the message that the service guy told me, not the mechanic....

Actually, the Volvo I had DID NOT have the access port. We ended up cutting a hole on the subframe to save time as it would have been a 10 hour job. Stupid German design.

I looked at the parts list, I can't see any parts that can come loose and roll around like a screwdriver. What do you think it is? The fuel gauge sensor seems to be working alright, so I don't think that is it. Who knows. I will bring it back in next week. I guess the fuel tank gaskets are special ordered item...

phunk · 08-05-2011, 08:09 PM

there is a very poorly attached baffle on the drivers side tank just behind that access port that i could totaly imagine breaking off inside the tank.

there is an in-tank siphon line that isnt attached too meticulously either.

Do these cars have a little flapper door where you insert the gas nozzle when filling up? I always thought mine did but the other day i noticed there isnt one there. i wondered if it broke off. I havent seen it down in the tank though and i have been in there a lot lately. havent really thought about it again until now.

ChrisSlicks · 08-05-2011, 08:52 PM

There is no flapper (or flapping) so don't worry yours hasn't gone missing

It sounds like something hard (like a screw driver), so I am betting a baffle plate. Now the question is. If it is indeed that plate, is it screwed on so they can fix it or does it need a new tank. If they remove it, would I get even more fuel starve...

And WTF, you guys drive it more and harder than me and yours are still attached!

travisjb · 08-05-2011, 10:27 PM

mine ejected out of the fuel fill port

you called it, broke the stupid baffle plate and they said they have no way to fix it. a new gas tank wont be here till friday

why me

phunk · 08-10-2011, 10:13 AM

you mean they didnt want to try and weld it back on???

lol, i would ask for money of equal value to the tank and labor and forget the tank. that baffle isnt going to do much of anything anyway!

cossie1600 · 08-10-2011, 10:18 AM

lol i can see the guy being on 1000 ways to die if he tries....

the baffle isnt screwed or bolted on? how does a stupid welded piece come loose!

the dealer thinks they can have it back in in one day. i think thats too optimistic. what do you think?

Elysium · 08-10-2011, 02:28 PM

I have been experiencing the same issues on sweeping right handers as of late.
The car is going into the dealer to replace some parts in the tank including the sending unit.

I'm in for updates on the solution!

phunk · 08-11-2011, 02:27 PM

just wanted to update... this week we had to spend a lot of time on other projects and tuning our TT 370.. this weekend i am out of town, but starting first thing next week we are going to begin wrapping up our 2 different solutions for fuel surge issues for you guys.

cossie1600 · 08-15-2011, 11:31 PM

Sorry to be off topic, do I need to redo my alignment after a fuel tank swapped

phunk · 08-16-2011, 04:46 PM

it would be recommended to have the alignment checked. its not difficult for them to set all the alignment hardware exactly how it was... but it may be possible to slightly shift or alter the crossmember mounting... which would shift everything just a little.
