I was told by a tech at NAPA that they no longer make Y block fuel pumps with glass covers over the filter. My 1956 F-250 had one of these filters with a  paper cartrige changable filter. All the filters for that listing were the wrong size. He looked under F-600 and found NAPA 3943 which is the correct gasket. NAPA crosses with FRAM CG7 for anyone who is looking.

Now the sad part of the story is he told me when this pump quits working there is no replacement that looks like it. I spent hours polishing and cleaning it up, hoping I would have its nostalgic look on my Y block forever. I even wanted to find another one like it to put on my 292.

Is it true they are obsolete and not even rebuild kits are available?
 
The pump was made in USA by  CAR BURE TER with the "BURE in smaller text. It has a number embossed on it: O-1583, it has L5 embossed on it, it has a couple of X's embossed on it. It has a 6 embossed on it.  Its made of cast aluminum with a glass fuel bowl showing the filter.

Can anyone tell me if they are non replaceable when they fail?
