Okay any of you guys out there replace fuel filters very often? I usually do it once a month on my 85 GMC Sierra Classic just to be positive that everything flows well, plus its cheap like 1.89 a month. Especially on the new 350. I was thinking about putting in a inline clear filter before the carb but just haven't. Anyway last time I did a change I lost the seal that goes between the part(cup like) that contains the filter and threads into the carb itself. (4barrel Quad Jet Carb) I can't find a replacement seal anywheres everyone seems to have one that they claim fits but none do. Any other ideas of how to seal that sucker off. Right now I am using a seal not made for that and I had to cut it to allow it to fit all the way around and it doesn't leak so I consider myself lucky and just left it.
