So I was in at my local Isuzu dealer and picked up the new Fuel Sending unit that I will be installing later this week. The parts guy said that he thought I might need to have the computer reset afterwards in order to get the proper reading. Has anyone here changed their FSU, and if so did you need to reset the computer afterwards?

He recommended leaving the battery terminals off for about 15 minutes after the job, and that this might avoid the reset.

I'm not sure about the later models, but with my old 89, that is the reset.

I've seen no rhyme nor reason as to who needs the reset and who doesn't. I put mine in my 98 and filled it up and it's worked fine with no reset.

Others have done the battery disconnect to no avail. They had to take it to the dealer to get it to work.
