I am planning on changing my fuel pump and sensor assembly along with changing out the old injectors with the new ones. I also want to change all the O2 sensors.

For the injector and fuel pump assembly change, I want to know what parts besides the 2 I will need for the job. Will I need any gaskets for changing the injectors? And for the fuel pump change, are there any parts like o rings and stuff that I should change since ill be dropping the tank?

Also will this be a good time to change out the fuel lines? I heard ethanol fuel beats the crap out of the fuel lines

And lastly about the O2 sensors, Are there 3 sensors total on the car?

Thanks a bunch!

 

What year? 2 door or 4 door?


The fuel pump needs to be AC Delco or Delphi. Shouldn't need anything else. Make sure you solder the new connector to the vehicle harness, no crimp connectors allowed At the module connector pigtail, solder a 14ga wire to the two black wires and run it to a good clean chassis ground.


Don't bother replacing the downstream oxygen sensor, unless there is a DTC in memory for it. The only thing that sensor does, is monitor the converter. It has no affect on engine performance.


The injectors need to be a good name brand, and you will need the updated bracket, some upgrades come with it. You will also need an upper intake, (plenum) gasket set.


You can be proactive and replace the steel fuel lines, or be reactive when they leave you stranded somewhere on the side of the road

 

Oops! Forgot to mention the info. Its a 2001 4x4 4door.

For the fuel pump im getting ACDELCO MU1733. Ah crap, I suck at soldering, I can only imagine it would be worse doing it under the car.. Cant I just twist the wires together and have those heat shrinkable covers on them + heavy electrical taping to get water out??

For O2 sensors then Ill just have to get 2x ACDELCO AFS105?

For the injectors I wanna get the ACDELCO 2173028 and in the picture on the listing it shows a bracket.

For the fuel lines, I found two kits
FINELINE FL442B More Information for FINELINE FL442B
FINELINE FL485A More Information for FINELINE FL485A

Do these 2 kits include all the parts?

 

You could just twist the wires and use electrical tape, but I absolutely would not. I can't imagine that would last very long at all. You would be better to find a friend who is good at soldering.
