Bf109 Fuel Filter??

Morning

I have recently purchased what I think may be a fuel filter housing from a 109, it has a label denoting that it was made by DBU Berlin (a manufacturer of fuel pumps and related products).

From a look at images on google there are technical diagrams which show a 2 simular shaped objects as being fitted near to the engine bulkhead, however the picture are not clear enough to be certain.

If anyone has any better images or any further knowledge that would much appreciated

Thanks
