This is a Hardi Model E57 DBGM fuel pump and pressure regulator for the Eberspacher B2, BN2, and early BA4 gasoline heaters found in many VW and Porsche models.

I do not know in what particular models these heaters were available. I do not know if it functions properly, but the fuel pump runs when connected to 12 volts.

Here is a used fuel pump by itself for sale for $65:

What you see in the pictures is what you get.

I got these in a parts lot with a '66 Porsche I recently purchased. The owner had a collection of random Porsche parts he kept on hand when he owned an import repair shop. See my other auctions for more parts.
