Fuel Tank Caving In?

[AngryRB]

I noticed while under the car that the fuel tank looks like its out of shape, almost like its caving inwards?

the car has been sitting for over 3months doing my turbo upgrade and has a quarter tank of Eflex in it, I noticed the 20L plastic fuel containers in the shed are the same, they look like they are caved inwards..

I cant remember really taking note of how the fuel tank looks before, so can some people check to see if this looks normal?

eh?

The fuel cap should release pressure ? (allow air)

Are you saying the containers are caving in like semi empty milk container with the lid screwed on ?

Temp related 'Warm v Cool' ?

the fuel cap hasn't been taken off for about 4months, yeah caving in like if you pushed the side in on a half empty mild bottle,

when it was last filled the temps would of been warmer than they are now, do you think that's the issue and that the lid needs to be taken off every few weeks to relieve pressure?

Cant hurt

I'd say Nissan have this covered off. So will wait and see what 33 owners have to say about Fuel Tank shape.

I know I get a woosh when I run the tank down and remove the cap to re-fill. So there is vacuum pressure.

I have a 32, so cant really comment on the shape

[AngryRB]

can anyone confirm if the picture shows a normal tank or is there an issue?

I just removed the cap and there wasn't much 'woosh' from it,

hope I havnt asked a stupid question here but is this actually a the bottem of the fuel tank or am I looking at where the spare tyre sits?

I'm pretty sure you are looking at where the spare tyre sits.

Before a flight, if I ever see a misshapen wing, I'm not getting on!

The picture is of the spare wheel carrier in the boot.

In a R33 the tank is in front of the rear diff, made of black plastic and takes the shape of the underside of the rear seat,

You do not have a problem.

that's a relief, had me confused for a while there,

thanks for clearing it up for me
