Whats all involved in dropping the gas tank, do you have todisassemble the rear-end. I have to do this because a previous owner of the car went with the trap door method for the fuel pump and it looks like they cut it with a chain saw. I am going to make a removable plate over the hole as I dont know if fuel smell is a problem as I havent drove the car since its sort of in pieces.

Wouldn't it be easier to use a set of pneumatic shears to clean up the cut, then install
the plate with the tank and pump still in-place? While it's open, check the lines and
make sure all 4 are properly connected.

Carefully cutting the trap door is so easy, just plunge through very slowly with a cutoff wheel. I would NEVER drop the tank.

Fuel smell should never be a problem if everything is installed correctly and functioning. The tank access to the FP and sending unit should have a air/fuel tight seal and the vapor from the tank should be sealed in the charcoal canister system and purged into the intake manifold at the TB. The gas cap is a one-way valve in only and should not leak fumes. The trap door cover is to block out outside elements like dirt, splashed up water, outside air and noise.

I also went thru the rear pan to access the fuel sending unit. Very easy to do maintenance.

Guys, I could really use some help here. I've done all this, but it feels like there is something else holding the fuel tank in the car. I can tug on it & it's just not dropping. any ideas?
