What did he say was wrong with them? At one time you could buy the drain assembly from Ford and replace the whole assembly but I am not sure if it is still available. The only problem that I have heard with the fuel bowl or filter housing is pitting on the bottom of it to where it will start to leak in which case some have cleaned it real well and then placed JB Weld on it to seal it for while. If you do need to replace it I would suggest to get a hold of Mike R at Tousley Ford Parts Depot at 1-800-328-9552. They are a sponsor on the site here and sell parts at cost + 10% and should be able to help you. As far as replacing the housing or fuel drain if you can turn a wrench you should be able to replace it with no problems.
