Change in 2017 Fuel Cell Rules


Recommended Posts

I'm looking at the change in the fuel cell rules for 2017, namely where the 2016 rules stated: For those teams having a STOCK fuel tank of 18-20 gallons, Chumpcar will allow the use of an SFI/FIA certified 22 gallon fuel cell. 


This rule notably absent for 2017, replaced with: Fuel cells shall be limited to the stock, OEM fuel capacity for the make/model of car, plus-or minus (+/-) two (2) gallons.


We have a 19 gallon OEM tank and had initially planned on getting a 22 gallon fuel cell as it is a very common size available (picked one out from JAZ). However, with this new rule I believe we can only go up to a 21 gallon fuel cell which I haven't found yet. Do I need to be looking for a custom fuel cell? Are cars which previously had an 18 and 19 gallon OEM tank banned from using the fuel cells they installed in their car for 2016?


I can look in to getting displacement balls for the tank, but a gallon's worth of balls is significant and I've never had much good come from having a lot of them tied up in the tank.

Might take a look at this thread if you haven't seen it.  Also, I found 1 gallon blocks on the internet for 85-100 bucks.  I don't know how cheap JAZ cells are, but a good one from ATI or FuelSafe seems to run around $1,000 depending on the capacity, features, options, etc.  If you're spending that much, another hundred bucks doesn't seem like a big deal.  Or you could go with an 18 or 20 gallon cell since those are both legal...

The 22gal cells are common in circle track and can be bought on the cheap.  I bought ours used, with complete fill plate and rollover valves for $400.  Although I still have over $1000 into it after replacing the foam, bought new pump, lines and installed it.  I do feel much safer with the cell though, it was worth the cost IMO.


Dimond, we're in the same boat except ours is already installed.  Run the 22gal and put in a displacement block.  Take a pic of the block installed (since that is supposed to count as proof :wacko:).

I tried to use oil quarts bottles for displacement, and even though I thought I had removed all the decal glue, I plugged my fuel filter and burnt out a pump. At least I think that is what did it. So I pulled the quarts bottles and put in metal quart paint cans from home depot. There were only a few dollars each and come as bare steel, maybe a small barcode sticker to be removed. To displace 1 gallon with 4 quarts cans would be easy, but I have foam to keep things from banging around and I have a lot more than 4 quarts cans in my cell !


All I learnt from this experience, is don't assume a new cell is clean inside and/or don't assume that you can clean all the sticker glue off a plastic oil bottle. The gas will eventually remove it and plug your filter.
