As some of you may remember, I had fuel pump trouble with my '67 Fury hardtop with the 318 engine back in December. I replaced the pump with a new one and it has been fine. The pump that was on the car looked fairly new but it was on the car when I bought it a year ago so I do not know how old it really was. I was using the CD-2 lead subtitute as directed in the fuel tank for valve seat protection because it is the original engine. Could that have messed up the pump and caused it to fail? Thanks for any info.
