Re: weird fuel leak from the sending unit on 69
Michael, just checked ebay for 3774937 retainer cam. There are many available and most very reasonable. All GM NOS show the taller bends as is needed. The repro cams, even the Canadian ones all seem too flat which may be causing many of these leaks. As mentioned the sending units riveted electrical studs gasket have also leaked on the repros.
