70_Fastback: RAT ROD - 193x Ford / 1942 GMC Truck

Those friggin' rods holding the column in place are genius.

That thing is gonna be too nice to be a rat, you better start picking a paint color.
 
There's other options besides "GO" color ...? :shrug

-----------------------------

And on a side note, I took the rat for it's first maiden, non-powered cruise last night. :yah
I wanted to test the steering while under movement. My driveway has a slight slope to it, so I unblocked the wheel, gave it a slight push, jumped in the seat and away I went down the drive, into the cul-de-sac.... and then out into the street. Little farther than what I intended.

But the steering works beautifully! It turns fairly sharp for what is, and it actually turns TOO sharp as the back of the tires will rub the front wishbones on a hard left or right turn. I will need to make some stop positive stops on the front axle for the spindles to cotntact & stop on.
 
Since my mojo is still going, I'm starting to mock up the location of the gas tank & figure out the mounting bracket.

This is the location that I have been thinking:

First, is the tank upside down though? Isn't that the supply tube adjacent to the sending unit hole?

The pic makes the tank look beat up for some reason, but it's not. It was actually a freebie from my Dad. It was too big to fit the turtle deck of his T-bucket. It's a brand new tank. And as you can see, there is no sending unit, etc. Maybe the local, resident sending unit specialist :::cough, cough, Craig, cough::: can provide me with some assistance on what to get, where to get it, etc.

The tank will hang down a bit, fairly close to the drive shaft, so the mounting bracket for the tank will incorporate a drive shaft loop in it as well. And the thought is to make the tank appear like it is floating, the bracket will all be below, and mostly out of site.

On that thought,

I made some assembly tables for our shop many moons ago and used the frame (2x4 box steel) as the air tank. Just had to make sure the corners were open and that the welds were good. It worked great as a air tank!

Sure that isn't the vent tube? Supply should be part of the sending unit.

Looks like it belongs there! Keep up the good work and the pictures :pbj
 
Naaaaa, I remember ACs doing a bike like that. If they do, it's got to be OK.


As far as the tank, it looks like it sits correctly to me. My fuel cell has all the plumbing on the top.

There is another tube, adjacent to the filling tube inlet on the side. I thought that was vent...?

You're right, I didnt see that one till you mentioned it. Does the tube on the top continue down into the base of the tank?
 
That tank does have me intrigued. Hot rod tanks typically have the sender on top of the tank and the inlet on the end like yours is shown. What I'm not sure about is how the fuel is delivered. Below are two pics of a few tanks

No it does not continue inside. Hence why it makes me think it's upside down. Much like our Mustang gas tanks. The outlet & sender are on the bottom.

But if I flip it, the fill tube will be on the bottom & facing downward. :shrug

:confu Last guess for me..... maybe the supply comes from sending unit and thats a return for EFI cars....
 
Just modify to work as you need it. Something tells me you might have the skills to pull it off.
 
What are your plans for a fill tube... will the cap be vented? It seems to me as that would govern what you do with the top vent port. If you have a long fill tube, then the side vent will run to the top of the filler pipe. I think you would be fine with a supply tube incorporated into the top mounted sending unit. Once the tube is primed, I wouldn't expect the gas to flow back so long as the bottom of the supply tube is always submerged... on the other hand, where the tank is exposed, I don't think I'd want the fuel line running above the tank for both cosmetics and also the potential for the sun to bake the line on hot days... it should be very easy to install a bottom mounted supply line, especially with the large access hole on top. btw, progress looks great, nice work on the connecting rods...
