...Also found code P0452 hiding in there, it too passed and started working again. Now do I buy just the pressure switch or a whole new fuel pump assembly and lock ring?

It's more likely to be an actual leak than a faulty pressure sensor. Maybe she left the cap loose recently, fixed it, but the code is resting at "pending" status until the drive cycles are completed?

My daughter loves the Morimoto fogs I got her for the Sierra.

Last night, after dinner, a Service Four Wheel Drive message popped up on the DIC. Would not shift into Auto or 4WD or anything. Turned it off after we got home, scanned it and got code B2725 but it passed on next ignition cycle. Going to replace the switch anyway. Also found code P0452 hiding in there, it too passed and started working again. Now do I buy just the pressure switch or a whole new fuel pump assembly and lock ring?

Your Tech 2 can read the fuel tank pressure sensor value. If you want to see it change, check for response by running an evap purge and seal.

Searching for advice. Need to travel about 50 miles to get my tires replaced. How much damage will i cause if i run the stock 17" (265/75R17)spare on the front left while my right side is a stock size 22" (285/45R22)?
Its a 4x4 but stays on 2wd most of the year unless we see heavy rain.

I vaguely remember this difference in size being and issue. Can't remember if it was for awd vehicles only

I’ve had a leaking seal at the output shaft of the front diff since I bought it. Driver’s side. How hard is that seal to replace? Can it be done in place?
