Yes there is a filter before the carb. I have ordered a new one.
How should I attach a ground wire to the tank?
The manual does mention a couple of rubber strips on top of the tank.
'pad' between the tank and trunk floor what should I use for this?
Do mean paint the bottom of the car or the top of the tank Home depot sells the spray rubber coating by the can I was thinking about primer the top of the tank and using the rubber sealant spray on the bottom. I saw pictures of a car with a new tank and it looked good in its natural state.
