33 Coupe Interior 30        10/02/04

One of the things I bought for the tank was a filler-neck and cap. After I did some measuring on top of the tank, I would need to cut the filler-neck down to a smaller size. After cutting off the top I also put a relief in the underside of the neck so the material thickness would be closer too the tanks thickness for welding purposes. 
 

 

 

Another item that was needed is a sending unit for the fuel gage. This ones made by VDO but as you know, I have Autometer gages. Why didn't I buy a sending unit from Autometer? They don't make one if you can believe that so I had to go else where. This sending unit is adjustable too accommodate different depths of tanks from 6" to 30". It also came with a gasket but no locking nut so I'll have to come up with some way of fastening this down on my own. This has a two wire hookup (gage and ground wires) just like my other tank does so the wiring is already in place.
 

 

 

This unit came with a chart to help you calculate the length of the sending unit to the depth of your tank. After measuring the depth of my tank, I needed to remove one piece of the sending unit so it would work with my setup. I also needed to drill out one of the holes in the sending units support so it would work for me but it's wasn't a big deal. Now that the sending unit has been set for the proper tank depth, I'll need to measure and cut the float arm to the right length.
 

 

 

Too make sure I had the float  arm on the right side, I hooked up the gage wires and then moved the float arm up and down while I watched the gage from the outside of the car through the rear window to make sure that it worked. I also put a "F" (full) on the sending unit to remind me later so I didn't get the float arm on backwards. If it gets installed the wrong way, your gage will read "full" when it's really "empty" and "empty" when it's really "full".
