The Casper'* hot wire will not work on 96-99 Bonnes; actually no one makes a fuel pump hot wire kit that works for us 96-99 guys. If you want a hot wire you will have to make your own.
Be prepared to pay about $300 for a new Ac Delco sending unit. Currently I'm in the search for other sending units and I've only found 1 that might work and Rockauto.com carries that one which is about 1/2 the price; but the quality is unknown. TREperformance.com has a 255LPH pump ( model 340 used in Mustang applications but is not listed as compatible with 96-99 Bonnes on their site) which will work on our cars with little modification if you choose to go that route.
