When I was ordering my new fuel pump and hotwire kit from racetronix,the sales rep. or customer support guy called me and suggested a new sending unit. I initially thought he's trying to sell me parts I didn't need..... he described what my sending unit would look like after 26 years (RUSTY)... I went with his advice and was glad I did!!! Also check your steel fuel lines near tank... easier to replace while tank is down. I found small hairline cracks in mine after moving them around to disconnect from rubber couplings .. Racetronix was right on target with their advice.. great product and my sending unit is right on the money. Add 5 gallons and the gauge matches...
