I "inherited" these fuel pumps. I don't know what they are for or, if they are HAMB friendly or, their worth . I know they will be easily identified here but, I never saw any pumps like this. Thank you.
Yep - there should be a # on the perimeter that bolts to the block - looks like a Stude the first picture or two - and a later flathead that also runs the vacuum wipers. Maybe I can post a sample tomorrow....
