I have a 1997 2500 with a 24 gal fuel tank and would like to change it to a 35 gal. tank will it fit?

 

yes, but you might have to change the straps. and the fuel pump for sure, and the fuel lines themselves might not be long enough.

 

if you have a Club Cab or Quad Cab style Ram
you need the special
34 gallon fuel tank
found on V10 engined 2500 series Rams

this special 34 gallon tank
has a different shape than the long bed 36 gallon tank

Living in a rural area, I need all of the fuel tank range I can get. I've
been wanting to convert the fuel tank on my 2001 Ram short bed to the larger
34 gallon tank from the 2500 series for several years now.

I completed the swap today with the help of a dealer about an hour away. I've
personally gotten a lot of misinformation from owners and dealers alike as
to what parts are needed to make this switch work. Here's some information
for anyone wanting to do this:

The part number I used for the tank is for the ¾ ton of the same
year-52102241AD.

This tank is 8 gallons longer, but is the exact same depth as the 26 gallon
tank. So, no new sending unit or gauge assembly is needed. The old unit
swapped with no issues.

The mounting straps are the exact same for both tanks. Some pictures I
looked at on the web showed an additional bracing shelf was used across the
front of the tank. I found that the front end is very tight and does not
flex at all, so I chose not to add this shelf.

The old tank heat shield continues to be used. You don't have to purchase a
longer shield because the 34 gallon tank has some kind of attached heat
shield ( looks like tin foil).

I was told there was no computer reflash available for the onboard computer,
so I don't know how accurate the Distance to Empty will show. I'll find out
when I fill the tank up (yet to do).

I was initially quoted 3-4 hours labor for the swap, but the dealer got it
done in less than 2 hours. I don't know how much of this works on other year's
trucks. Overall, I'm very pleased. Hope this helps anyone considering doing
this.

Hello to the forum!

I've got a 2000 Ram 1500 quad cab short box, 5.9L. It's got a 26 gallon tank, and I find it to be very limiting when towing my camper around - 8-9 mpg won't get you too far with only 26 gallons

I see that the short bed 2500s for the same year have a 34 gallon tank, and that would make me feel a lot better while tooling around in the backwoods of Idaho.

Is there any reason why I couldn't swap in a 34 gallon tank in my truck?

Thanks!!
Dan

 

No reason I know of that this can't be done, but I've merged your thread with one that has more info.
