Fabricating a stainless efi tank for my 1965 mustang and EFI conversion
I am finally getting out of the stone ages ;D and putting efi on my car this winter. Along with that the other goal of this winter was to quiet the car down. We go on a lot of trips with it and it was on the edge of being to noisy on the inside despite all of the insulating I did.
One of the large culprits of all of my noise was my fuel pump, so I decided to build a new tank and mount the pump inside to kill some decibels. This will also get rid of the sump-ed look from the back of the car. In addition to quieting it down I wanted to add some fuel capacity at the same time. A fuel cell is out of the question as the trunk space is a must.
Here are some pictures of what I have done so far:
This piece will be a recess welded into the top of the tank for access to everything inside and the wiring will bulk head through here also. The reason for the recess is on the old mustangs the top of the tank is also part of the trunk floor. There will eventually be a cover over this so it is all hidden and protected.
This will be the top of the tank and the trunk floor. It is raised 1 1/2" from stock to increase fuel capacity.
This is the main body of the tank. It is 1 1/2" deeper than stock to add capacity.
Here is basically what it will look like once assembled. Like I mentioned the piece sitting on top will be cut in and recessed down.
The pump will mount inside of a "baffle pan" I am going to build this week. There will be quite a bit of internal baffling to keep the sloshing to a minimum.
The supply and return lines will be internally plumbed to ports that will exit on the passenger side of the tank. With the top being in the trunk I did not want the connections coming out of the top.
When all of the welding is done it will get either a brushed finish or painted, not sure on that yet..
