HI THIS IS FOR A VINTAGE AC FUEL PUMP #4052 I THINK MAYBE FOR A 1954 FORD MERCURY V8 ? OR OTHERS ? I AM CALLING IT USED BUT IT HAS REBUILT ON THE BOX AND PUMP I GOT IT FROM A STORAGE UNIT WITH A BUNCH OF THESE OLD PUMPS I AM SELLING IT AS YOU SEE IT I AM ONLY GOING BY ONES I SEE ON HERE THAT LOOKS THE SAME AS THIS ONE BUT I HAVE NO CLUE SO MAKE SURE YOU LOOK OVER ALL PHOTOS AND MATCH YOURS UP SOLD AS YOU SEE IT UN TESTED AS YOU SEE IT STILL NICE FOR A 60 YEAR OLD PUMP...
