Aluminum Fuel Tank Project / EFI Fuel Cooling

I have been side tracked with other projects around the homestead for a while.
I am getting closer to finishing this project.

I now have the tank welded and assembled.

The welds are not pretty, but they do not leak.

I pressure checked all the welds and connections with 5 -10 psi air and plumbers soap solution.

I did have a few leaks but now have them fixed.

Here are a few update photos.





I needed a way to pass the power wires thru the tank.

Here are all of the parts that I used.




I used three 5/16" x 3/4" nylon bolts and nylon nuts.

I shortened the bolts to 1/2" long.

I chucked them in the lathe and center drilled them and tapped them for 8 x 32 machine threads.

I used all stainless steel componets.

I used permatex thread hi temp sealer on the stud thru the nylon bolts and Loctite red on the nuts at the head and nut end if the studs.

Here is a photo of the power and fuel AN-6 return and AN-8 supply connections on the outside of the tank.




Here is a photo of the power and fuel AN-6 return and AN-8 supply connections and the fuel pump on the inside of the tank.

There reason that there are three wires to the pump is for the future.

IF and when the A1000 pump gives up, I am going to replace it with a Fuellabs pump and regulator which needs the third wire to control the pump speed.






I am going to convert the 1967 tank strap to a 68 and up style of dual strap mounting.

More on that in the next few days.
