My 1989 fuel guage has not been showing the right fuel level for about 3 years so I decided to take the assembly out of the tank. The float looks good. I have heard of these problems in other C-4's but could not remember what the cause was. With a 1/4 tank still showing on the gauge the gas tank is empty. Also I thought I would replace the fuel pump while I got this apart. The car has 20,000 miles on it and I know the electronics can go bad. Any help on this matter is much appreciated. Also what brand of pump would you recommend, NAPA has one for about $80.00. john
