Question about Chimaera Fuel Tank Baffles

[NJ94Chim]

Greetings all.

I have a 94 Chimaera 400. When I'm driving at lowish speeds (15 mph or so) and turn the car tightly enough, I prettty consistently hear a "clonking" type sound from the trunk area. Happens on both left and right hand turns. Gas tank is maybe 2/3 full (which is about as low as I will let it get to). Car has no fuel leaks.

I've seen a couple of posts that mention that the Chimaera fuel tank has internal baffles....is it possible for the baffle(s) to come loose and move around with the sloshing gas - ie be the source of the clonking sound?

If loose baffle(s) is/are the source, can the tank be removed and repaired?

Or maybe its simpler to buy a salvage tank and refurbish it?

Or maybe just buy a new aftermarket tank?

What are the group's thoughts?

Thanks in advance,
Guy

Sounds like you need to identify the cause of the sound definitively.

If it is related to the tank, it's not difficult to take it out/replace it.
I wonder (thinking aloud) whether the internal filter might have come loose, though it's lightweight plastic and probably wouldn't clonk.

This article is useful info either way - and it has a photo of the outlet fitting.

If you haven't done it already, it might be worth loosening the straps that secure the tank, pulling it forward an inch or two to peer down the back of it - there might be something down there. It would ring like a bell if something is knocking against it.

Are you sure it's not something to do with the anti-roll bar, suspension, wishbones, or as others have encountered - the hubs when worn can make a sound (though it's more of a graunching noise).
