Slowly but surely I am continuing work on my Datsun 510. I am installing a firewall between the stock fuel tank and the driving compartment. Here is a pic of what I have done so far. The center portion I need to be able to access if I need to remove fuel lines for replacement or even if I need to replace or remove the tank. Is it allowable to rivet an aluminum sheet over that opening?
Ok I think I might have found the answer in case anyone else needs the info. Over on Dirty Impreza I found a post that showed the exact question I am asking and nobody seemed to question it at all. I still don't know for sure if it is legal but i will go ahead and do it. The worst case is I drill the rivets and weld in a piece of sheet metal.
Thanks I will get some of the caulk and and go over all the seams.
Glad to see another brilliant Rally car choice and sad that more parts will be siphoned off of E-bay. Our panel came fastened on with sheet metal screws and I never really was comfortable with it. I am in the process of doing what you are but leaving two small rectangular access panels at the tank bolt locations. I have a tube of fire caulk ready on the shelf but have not done a gasoline test on it yet. This caulk is for construction use to prevent fire/heat from traveling from one cavity to another but not necessarily in contact with chemicals. I think even if it gives you a few seconds more time to get out of the car, all the better.
What engine are you going to run with? Post some more pics when you can.
#727 Datsun 510
I am currently using a L18 with a 280Z 5 Speed. I eventually will upgrade to either a KA24DE or SR20DE but that is in the future. Right now I am trying to get this car together so I can rally. I will post some pics up this week. for now here is what I have done so far.
The previous owner had added speakers in the top tray so there were three very large holes that needed to be covered. I used Alu. there as well. I am going to get a right angle drill from work so i can make the panel a little more tight up against the existing sheet metal. The triangular piece of Alu. is not riveted in yet and i still have some holes to weld up.
