Hey guys How easy is it to replace the rear seals in my 177, I'm getting some fuel in the rear reservoir, I had a friend who supposedly knew how to rebuild superchargers rebuild it, Now fuels leaking into my reservoir and I'd rather not take it back to him if I can just pop a couple seals in there, thanks

Im about to attempt the same thing next month..the seal kits are about 60 bucks....thats as far as I have got.
