Replaced Fuel Sender - won't start

[scottvd]

Ran fuel pump for 30 seconds, no change. Pulled the sending unit out again, found one of the fuel lines disconnected. Reconnected it and was able to pop it off again without depressing the side release button :/

I tinkered with the locking mechanism using a precision screwdriver and reseated it, it popped off again. Repeat, and it felt kinda snug? Not sure. Put everything back together, ran fuel pump 15 seconds, car fired right up. I have about 40% confidence that hose will remain connected. :/
