OER now makes a Delco service replacement available on classic industries. Price is pretty good too. I don’t have personal experience with OER but it’s an option. I also think Hawks sells refurbished factory units at like $300, I can’t remember for sure.

how long do they last
I mean my factory gauge is still working since 88

 

Really depends on the condition of the inside of the tank. If it’s in good shape they can last quite awhile but if the car sits for a long time with ethanol gas in it they can get nasty and fail. Also if the lines at the top are rusted/corroded then replace. I believe most shops will replace sending unit when they do the pump if that means anything. On these cars with the labor to drop the tank I would do that as well.
