fuel tank size?
 

how an i tell how many gallons it holds without filling it up? trying to get a new fuel pump, but there is two different ones for the different sized tanks :icon_nut:

It could have either a 25 or 31 gallon tank. If your truck still has the RPO code sticker, I believe the one for the 31 gallon tank is NK7.

Im hoping you are getting a genuine ac delco,and not a cheap pump.

i was looking in to delphi pumps, are they the parent company for delco? if not is that a good pump?

rriddle thank you. You were right. It say NK7 :)

delphi and ac delco are #1.
