Well I had to pull the fuel tank on the jimmy this weekend, it's sat dead for awhile, and I think it's because of the sediment clogging up the fuel pump. Well I drained it and took it to the carwash and sprayed it out the best I could, shaking it trying to get the 30 years of sediment out of it, well there is still some in there, any ideas on how to get the rest out? I don't have a welder so I really don't want to drill a hole in the corner. Also isn't there some kinda of treatment stuff you can put in there to kinda seal/preserve the inside of the actual tank? or is that just a service that's done professionally?
