typ001 T ok guys here it is. I have an 02 2500hd ls model chevy. The other day the fuel gauge went nuts, and continues to act up every time it is driven. Ive ran it down to the fuel sending unit. Im going to just go ahead and replace it next week and I found a few online. Question is, is there a fuel pump in the the tank or is it on the rail or is there only the injector pump. I'm wanting to make sure before I go buying the parts I need. I checked online and found all kinds of people saying its here or here, but could never really figure it out. Just wanting to make sure of things before getting elbow deep in the project. Thank you #1 · Jan 18, 2016 ok guys here it is. I have an 02 2500hd ls model chevy.

I believe its all stock, and thank you #4 · Jan 19, 2016 Correct information can not given without first knowing what truck you have, Duramax does not have a fuel pump,... its an injection pump, (CP3), located on the top of the engine. Your problem sounds more like a bad stepper gauge in the dash/cluster. Insert Quotes Post Reply
