Fuel pump identification

[Vilike]

Hi guys.

I bought a broken '88 Black-Gold 3CW last year and i disassembled it for parts. The bike was in a really worn out condition and broken on its left front. Imported from Austria and broken by a boozy idiot.

So i tested all the parts in the past weeks and i found its fuel pump in a very good condition. But it was unkown to me. I Googled it and i found out that its not a stock one and not a FJ-related aftermarket product either. Or am i wrong ? It was on the bike's right side under the side-cover at the rear Shock.

So the million-dollar question is : What kind of Fuel pump is this one ? Can anyone recognise it ? Thanx guys !
