33 Coupe Interior 36        10/16/04

This is what it looks like finished. Notice the hold-down brackets in the front. These are made from 1/8" thick angle iron which measure 1" X 1" X 1 1 3/16" with a clearance hole for a 5/16" bolt. In the back of the tank I ended up using the 5/16" studs that held in my other tank so that made it easy for the rear but I'll have to drill new holes for the front mounts. I also had to make sure where the new holes were going to end up under the car so they wouldn't interfere with something else. I'll be using some stainless button head cap screws on the two that will show. 

I took the tank outside, capped off the two fittings in the sump and filled it with water so see if I had any leaks. Sure enough, it had a few so I marked the bad areas and then welded them up and then retested again. I had to do this three times till I had all the leaks fixed. I do have one more problem that will have to be addressed and that's the filler neck. When I cut and relieved the inside of the neck for welding reasons, I went just a little to far because it leaks through the threads when I was shaking the tank from side-to-side with water in it. I think I can use some kind of sealant on the inside of the filler neck to fix this problem. The fuel sending unit screws all leaked too so I'll have use some sealer on those as well. I thought it would leak around the outside of the sending unit because of how warped the tank ended up after welding. I didn't think that the screws would leak so this was a good test to see what would happen and I'll have to fix it.

Now that the tank is in position, I needed to redo the fuel lines because my new tank is in a different place than the old one is. What I needed to do was make the lines four inches longer on the inside of the car and while I was doing that, I also needed to cover the hole in the floor of the trunk where the fuel line exited.  
 

 

 

I made an aluminum plate that is 5" X 2 1/2" X 1/8" and put a 3/4" diameter hole in it for a 90 degree #8 AN fuel fitting. I used two 10-32 Riv-nuts to hold the screws in place and inserted them from the top surface. 
 

 

 

After installing the 90 degree fitting, I noticed that it didn't sit like I wanted. Notice how it tends to point downward. I couldn't get the threads to start on it because of this angle so I had to come up with a way to fix it.
