I just looked at an old one I took off the plane in 2014. There are no part numbers or Mfg name on it so I can't tell if it's Bosch.
But when I change the pumps out every 4 years or so I just order that part # E063502 from Wicks and it works fine.
Ray may have further info for you.
Have you found a non UL part number for this fuel pump?
