Hey guys new to forum I have a 69 396 long story short changed tank,sending unit and mechanical fuel pump and car still won’t start runs for a second with starting fluid and making a weird sound kind of high pitch squealing I hope it’s not a defective fuel pump again

Made sure it was up all the way guess it could have slipped down used bearing grease

Will try again tomorrow

Had to take pump apart to rotate housing inlet and feed to carb hope I didn’t mess up pump

No didnt prime fuel line gas ate tank away so I changed that will try air tank tomorrow thanks guys

I put about 2 gallons of fuel in after tank change
