Titan Fuel Tank.... For a HEMI!

[cdntrucker]

As of April 20th still waiting on parts. See attached for details.

Darn I'm on the edge of my seat, this better not be a cliff hanger.

Haha, thanks! How about door number three. It depends how people interpret what was written.

I added an arrow to the drive shaft for clarification of what was meant in that context. Of course the transfer case is much lower than that.

On the driver side there's part of the suspension that is already lower than the stock tank.

In both of these measurements the 50 gal tank appears to not reduce the effective clearance.

Only after installation will the hypothesis be confirmed.

When you are measuring from the control arms and the axle side of the drive shaft the you are not really saying anything about ground clearance as those parts move up and down as the rear articulates.

Waiting on Strap - No ETA yet.

for the new tank is a new fuel pump needed as the tank is deeper ? I know some on here earlier said you needed to correct your range on the computer but I’m not sure that’s right.

So mentioned a part number that might be needed. We tacked it onto my order, along with a few other things that /might/ be needed. Once the final strap arrives and everything is installed I'll ask for a final part list.

Ok I can wait to see the outcome I guess with titan / transfer flow they maintain the OEM pump . But being it’s an OEM part they do like to make everything special.

I had service department double check the list with techs and there was no mention that a new pump would be needed.

I was told still waiting on three parts today but didn't specify which ones. Going there Thursday so will provide an update then.

Really? Nobody can see that when you compare the parts list between a VIN equipped with 50 gal and a VIN equipped with 32 gal that they use different fuel pumps? How much deeper is the 50 gallon tank? I suppose that you don’t HAVE to change the fuel pump, but don’t be surprised if you have the same situation as when the CTD guys use a titan tank that uses the original fuel pump- the fuel gauge isn’t accurate for a certain amount of gallons when full and near empty. No amount of programming can change that, since programming only corrects the distance to empty.

has anyone dry fit the tank into place yet ? Do the strap mounts line up ?

it fits by measurement, we're waiting on parts and it will be installed

So your saying I should order everything now before the mad rush once you all confirm it lol

What about the actual strap locations? Assuming your tape measure hasn’t moved in the two pictures below, the straps for the 50 gal tank are ~43” apart? The straps on the 31 gallon tank are 23” apart.

I think you're saying that.. lol

Checking your local dealer for parts availability and installation costs would be the way to go before pulling the trigger for sure.

Good question. It's possible the straps are mounted on the frame at a new location.

These are going to be heavy duty straps one hopes.

 

[ThatAlbertaGuy]

I’m sure the straps are the same just would have to notch the frame and move the stud to the new strap locations ( a little more then just a bolt on install it seems )

We'll soon all know for certain. It'll be a first one for the dealership mechanics as well.

I just realized that with the 50 gallon tank on the Hemi, not only is the evap can different, but there is also a fuel isolation valve between the tank and charcoal can #1. I don’t know if the connector for the FTIV is present on all 2020+ Hemi rams, but the circuit definitely doesn’t exist on a 2019 Ram Hemi PCM (where the FTIV control wire originates). The FTIV connector and wiring will have to be overlayed in if it is not present on the 31/32 gallon tank equipped hemis.
