Custom fuel cells

[SchimmS]

After I received a quote from ATL for the custom fuel cell tanks we`re about to use on a GTR build I felt the strong urge to look for alternatives and found "Fuel Safe" in the US. Apparently they already built custom fuel cells for an Ultima which you can find here:
www.fuelsafe.com/catalog-2011/Page 18.html
Anybody here who knows about them or even uses these cells?

[RAT GTR]

I bought two for my GTR a year ago, and they should have all the dimensions necessary. The cells have passed safety tech for the racing I do with no questions asked. They are great people to work with, and been in the business for a long time with an excellent reputation.
PM me if you want any more contact information.

I still beleieve that once one of the new builders builds a tank that runs from side to side behind the seats in front of the engine we are all going to wonder why two tanks were nessescary. The room is there for at least 18 gallons of fuel in a single tank, lower in the car with way less plumbing and much less change in Center of Gravity during the fuel burn. Use the modern in tank pumps with remote pickups and filters inside the tank. Guys lots of folks have spent huge amounts of time and effort on all kinds of changes in the cars, different engines, tranny's ect. This effort will change the car more than all the twin turbo multi cammed piss pots that make less pOwer than the LS7 for considerably less time and money. O.K. I'm done with my rant. Lee ps as a idea of what could be done, what could you do with the headers if the tanks wern't in the way

Hey Bob, thanks for the reply - tried to send you a PM but the email system appears to be down right now. Could you please post the contact details here?

I have less than an inch between the pulleys and the firewall. This is a result of the dry sump setup and the G50/52 (requires motor to be positioned one inch forward). The only way to get a tank that is transverse in my car would be to put it in the cabin behind the seats, not interested. Agreed, this would be a nice option.

This would not be possible in the UK for IVA regulations unless a whole new bulkhead was created to separate the tank from the passenger compartment.

I wouldn't be happy with this without altering the chassis design in the engine bay either.

[ROWDYRENAULT]

Steve: The idea is to leave the exsisting frame structure where it is at, leave out the alloy verticle structure to the first cross member above the floor, Then develope a new steel bulkhead directly behind the seats. I come up with 16.75 gallons when I only use the space directly behind the seats not the side pods. This would put all of the fuel inboard, behind substancail frame work if you were hit in the side. Obviously you would need a tunnel in the middle for shift cables and brake cables but this tunnel could be built an inch or two above your floor so that fuel could move from side to side. You would need to baffle this compartment to avoid sloshing. I am going to try to copy a rough make that very rough scetch with this. Lee

it has already been done... rustys black gtr..

I do agree thjat those side tanks are a risk and my plans are to modify the chassis that a 100 - 120 L of Fuel will fit in a centre tank that will give me at least for normal driving a distance between 500 - 600 KM between refill.
I will also fit a Catch tank in the system in case of track day driving during low fuel runs to avoid fuel starvation issues.

Thanks to Bob (RAT GTR) I found a company in the US who builds the fuel cells way cheaper than ATL for instance. They have all the accessories I need for the modification (internal collector tanks with submerged Bosch 044, etc). I hope it`s ok if I post a pic of a custom Ultima fuel cell:

[deadscoob]

Those with internal 044s look perfect for Ultimas - how much were they? PM if you don't want to post?

It's things like this I wish/would like Ultima to be able to offer as an option to standard.

Thanks

[Steven Hung]

I am interest in the fuel cell. Where did you purchased them from in the US? Please PM the information.

I finally received the first "prototypes" of the racing fuel cells for the GTR we`re about to build. I must say that the overall quality is outstanding, the guys I dealt with were extremely helpful and experienced with this type of tank (surprise).
The fuel cells each have a built in catch tank with a Bosch 044 fuel pump that feeds the outlet on the inside. The tanks are connected via a D-16 connection in order to keep them level although that is not a big issue due to the 2 pumps feeding one fuel rail individually. On top you can see the sender unit (which can be calibrated to factor in the shape of the tanks), the tank vent (D-6) with the fuel pump wiring next to it and the filler neck that can be cut to the desired length. On the bottom of the neck there`s an aluminium housing which acts as a check valve in case of a roll over.

They do look cool but I dread to think what they have cost you.

Plus how much less (useable) fuel they will hold compared with standard.

The cells are of the highest quality with a seamless coating and have a FIA homologation number. The entire setup cost about 50% more than the factory fuel system with surge tank etc (which I admit works perfectly fine for all applications, these fuel cells where built after customer demand).

[crafty]

Guys,

Im clearing out Ultima stuff.

I still have a pair of brand new Fuel Safe cells - listed in classifieds

I paid USD4300 for them, they are sitting here doing nothing, so best offer by end of January gets them.

[crafty]

Anyone want these?

[deadscoob]

I can't believe you haven't had any offers. If I was building I'd have these over the factory tanks for sure.
