Follow-up Question on Previous Post re:GAS dripping from accelerator cover

Another member already gave me some good answers. I found out today from the previous owner's mechanic that 8 mo. ago he put a new accelerator pump diaghram in and told me the cover was warped so he had to machine it to get a good seal. Is it possible to use a good sealant around the edge of the plate to fill in the warped area? (I'm looking for the accelarator cover part on the classified) Has anyone done this before?
