Before I finish my swap
 

So Im pretty squared away with my 89 na to 89 turbo swap, just waiting on the starter so I can crank it!

Anyway I was priming my fuel system and noticed a humming sound from underneath the intercooler when the ignition is turned to on. WTF is this? and is something wrong?

You will be able to hear fuel pumping through the rails with the test connector jumped.

this was before I had done anything to the test connector...
