F7 / CF7 fuel tank?

[liquidfantasy]

If we are already talking about the GP-7 fuel tank, let's please also help me on the F7 fuel tank. I need to modify my Athearn RTR CF7 to look like the prototype.

The fuel tank on the model looks like this:

And I need to make it look like this:

Can someone help me on how to get this started? Any suggestion or experience here on how to do it? Are there parts outside to make the conversion easier? Any H0 scale manufacturer offering a correct F7 fuel tank for it's models I could order as spare and attach it to the ATH model? or is it going to end up in a scratch build project?

Thanks guys

Looking at Dave Hussey's Pbase site it looks like Hi-Tech makes the parts. Since CF7s were rebuit from F-units this should show most of what you need to know.

You need the Hi-Tech battery box/air tank and fuel tank. They are excellent parts.

Thanks guys, you are great! I'd be searching for ages without the support here

The HiTech fuel tank is a larger tank than what was commonly used under the CF7. It is a 1500 gallon tank compared to the standard 1300 gallon. The A&R photo shows a bit of a larger tank than the Santa Fe photo, so maybe this one was retrofitted with a larger tank? HiTech does not make the smaller tank.

If you go this route, you will need the fuel tank brackets also. I have all of these parts...I am planning on an F unit rebuild project.

Quite a bit of work will need to be done on the CF7 frame and new motor mounts will need to be made. I believe the best way to do this would be to cut off the battery boxes and tank. A flat piece of metal would then be cut to fit the bottom of the frame. This would serve as the mounting for the new battery box / fuel tank assembly. Then on top, I would use an ALine motor mount and install a can motor.

I will see how I get this done then. First I need all shipped, still a lot of things in transit ...
