okay, here is how I read the "great book of warranty".
"Chrysler must warrant the emission control system on your truck for the periods listed below provided there has been no abuse neglect or improper maintenance on your truck. Uour emmission control system may include parts such as the fuel injection system and engine ECM. Also include may be hoses, connectors and other emission related assemblies. "
5 years or 100,000 miles for short term warranty.
short term emission related parts:
" A warranted part is any part which can affect emissions"
7 years or 70,000 miles for long term warranty
" Long term emission related parts:
Catalyst, Cylinder head, EGR control module, Fuel pump
Turbocharger. "
It appears that the California warranty covered the tank sender replacement as it is part of the fuel system. I would say that I'm covered until 2003. 5 as I read this.
Hope this helps.
