tank swap

[nckcrdn_imp]

Hello ,I have a 2013 cb100abs and was wondering if i could swap to the 2017 larger tank without a hassle ? The 13 is 3.9gal the 17 is a 4.4 I believe. Just wondering if its possible .

Forum member chync put a 2017 tank on a 2014 (I assume it was the standard), so it ought, theoretically, to go on the 2013. http://cb1100forum.com/forum/showthread.php?tid=11505

Otherwise, peterbaron will probably drop in and tell you how he put a larger capacity tank on his 2013 and 2014. His looks the same as the 2013 bike, but is larger.

Yeap, thank you Cormanus..

In my case, '13 tank was replaced with OEM/16.8 L of almost identical shape, and I used the same fuel pump assy/gasket with a 3 pin flat/rectangular connector as well as the gas cap. Part was ordered through Samurider/Takashi

When I bought my '14 model CB, I transferred 16.8 L tank to it, and I had to use original ('14) fuel pump assy with a 4 pin square connector.
Mechanically, as far as tank, pump assy/gasket and gas cap are concerned = perfect fitment. Fuel gauge operates perfectly, and never ran out of gas.

As to '17 tank fitment is concerned for your '14 model, it should be OK.
You will have to buy a new gas cap and may need locksmith engineering involvement to code tumblers in order to use your '13 OEM key, otherwise, you will need a separate key for your gas cap.

I cannot advise you as far as the fuel pump assy is concerned, as I do not have any electrical diagram of '17 model, but assuming what Chync did , your conversion seems to be successful. Ask him.
Hope this clarifies your doubt.
Good luck with your project, provide feedback and pics when completed, please or it never happened.

Peter, just for discussion purposes. IIRC, without checking the diagram, the fouth wire is for the thermister on the ‘14s pump. The main fuel pump difference is the ‘14 pump flows more than the ‘13. Pressure is the same for both. I don’t know why the flow is more on a ‘14, but I bet I could easily make a ‘14 pump work on a ‘13 by using a 3 pin connector (which I have) and just leaving the thermister not connected.

Of course I don’t have a ‘14 pump laying around or I might try it. Fuel quantity might read wrong, can’t remember the details on that right at the moment. Just thinking out loud here.

I was only swapping gas tanks, f/pumps always were the same.
If you used '14 pump for '13 model you would only have to transfer 3 wires, as you said, and must use flat/rectangular block connector from '13 to make fit to its male harness connector.
