Greetings, I am having some rotted steel fuel lines replaced on my '97 CTD w/ 8ft. bed. The fuel sending unit has needed replacement for about a yr. now, I rely on the tripometer as to when to fill up. My question is: Has there been an update on the replacement sending units as to eliminate the need to replace this in the future? Unfortunately I am having my local dealer do the work as I do not have the time or facilities to do the work. Thanks.
