The fuel SENDING UNIT, and the fuel PRESSURE SENSOR, are two different things, correct? I ask because my truck is throwing a code for faulty fuel pressure sensor - giving me a CEL just in time for annual inspection...
My sending unit is/has been bad for 4+ years now - so I'd assume they're separate parts, considering the CEL just came on.
If they're separate parts, and I have to drop the tank anyways (for the pressure sensor), would it make sense to throw a new sending unit in at the same time for $15?
Also, the Sender linked on eBay above... It claims to work for Yukon/Yukon XL's w/ a 5.3 - but will it work for 6.0l Sierra's?
