67GTX440

I purchased a new Canadian made gas tank (Spectra-Premium?) for the 67 GTX as this was the recommended tank by many on this forum. Also new rubber hoses, clamps, strap and tank to filler grommet. I took this to a shop to be installed.
I picked up the car yesterday, and stopped to add gas since they had only put in five gallons of new gas in containers I had brought to the shop. When I filled the tank, I got about an additional ten gallons in before I noticed gas running onto the ground from the grommet where the filler tube went into the tank (19 gallon total tank). This dumped about 3 gallons of gas under the car and I was afraid to start the car for fear of gas leaking onto the hot tailpipe. I called a tow truck to haul the car back to the shop.
The mechanic said he put some lube on the grommet, but it was basically a dry fit with no sealant. Not sure what do do to get this fixed? Some sort of sealant that will bond with work with rubber and metal and withstand gasoline, or have to drop the tank to try another grommet?
The tank was installed with the filler tube attached to the quarter panel of the car and the tank slid up through the gasket and into the fill tube. Does the tank need to be installed and then the fill tube installed so the fill tube can be rotated into the gas tank through the gasket, or can the gas tank be installed on the fill tube from below with the sill tube in place?
The shop noted that the old tank seemed to be bowed out on the bottom as compared to the new tank. Does this indicate I may have a vent tube problem? They were supposed to make sure the vent tube was clear before they installed the new rubber hoses, but I have no way to know if they did. Is there anything to fail on the vent tube or filler (such as an internal flap) or are they good if they show no sign of corrosion or penetration? The car has always seemed to spit back a small mist of gas during fill up unless the hose was inserted upside down and gas was added very slowly.
The car was originally dripping small amounts of gas during fill up that I assumed was from a deteriorated rubber fill hose connecting to the metal filler. I just swapped out the gas tank and strap as they indicated the gas tank needed to be dropped and grommet replaced anyway to do this.
