The noise let's you know she's working. Haha.
If you need the hanger 2 they might be hard to find as a kit. I ended up purchasing the hanger separately and hooked it up to an aftermarket walbro pump on my 5.7tpi. No complaints as of yet. The pump is the same, Just need to splice the connector in. Cost was around 160, ish. Need to make sure she has good flow at 40 or more psi... 255lph@40psi for stock??? They have pumps out there relatively cheap 20-200 depending on flow rate/brand.. not sure what injectors you are running but you can't have too much flow in a return system. Bigger is better but could be overkill depending on what injectors you're running. Id pick up an adjustable pfr also. Nothing fancy. The screw type is working for me. All you have to do is hook up a pressure gauge to the rail to get her dialed in. I went with bbk but there are many others out there that all work the same.
Goodluck to you brother ✊

As stated, my car is all stock. I am not looking for a project, just R&R the pump (and whatever else might be bad, when I get in there) Thank you.

Id go with a walbro 255. Proven workhorse for the 3rd gen community plus gives you room to support more power should you chose.

Walbro 255 ? You do not hear it engine running? STOCK exhaust?
