Fuel Cell Super Thread

[chicane67]

Stick to one pump. Are you really set with using ATL... or are you open to options ??

Reason for question: I had a very long and in-depth conversation with Gary at Fuel Safe on just about every aspect of using the 'right' cell for the application. I'll tell you... I was all ready set to drop the $2500+ for the cell that I felt was necessary. Well... after the conversation with Gary... it was several hundred less and ended up with an even better result. I recommend that you give Gary a call... it's definitely worth your time.


Cliffnotes:



I am running a PC122'B' in aluminum. Its 25.5 x 17.125 x 13.75". It has an ST-100 sump/surge with ball check valves and I will be stuffing a Bosch (Kinsler part number 10211, found here, plus this info is a must read) EFI pump... which is the most used pump in this application. You can also find information on this specific pump at HRP. The cell has provisions for feed, return, vent, sender and a screw cap fill.

Now for the why. The cell is narrower than the stock tank by 11.5"... which helps with keeping fuel in the sump from reduced lateral fuel slosh and allows the exhaust to come out the back (like Rupp's). The cell is shorter in width than the stock tank by 6.875"... which allows you to locate the cell further forward to keep the weight closer to the axle and doesn't act as a pendulum when you are shaking the tail end and it helps with keeping fuel in the sump from reduced longitudinal fuel slosh... and it also provides you some 'crush' room in the event of an accident. Also, it allowed me to configure the structure for the chute anchor to the frame rails and build in some protection. The cell is taller than the stock tank by 4.75"... which when used with their uncut 12" fuel sender leaves you with 1.75" of "reserve" when the gage reads empty, which is 2.90 gallons... a built in safety. The particular Bosch pump is the most used pump in the our line of work... so they are every where... and finding one, if your pump dies at the track becomes easier... especially if it is the most common pump used. I also opted for an aluminum "Hat" can (similar to how Rupp did his)... so if an accident or gravity pulls the car into something more resilient... and it comes in contact with the ground or whatever... it wont spark. No spark, no combustion. Plus it's a little lighter. The "Procell" bladder is better for the climate that you (and I) live in... plus it's less hygroscopic and will live longer in the climate that you reside and the fact that you wont be emptying it and air it out after every use. FT3... is more than enough for what you have plans for.

Now... I should leave the reason for using the ball check valves vice that of the trap doors to your conversation with Gary. I'd try and explain it... but I don't have the time for the typing envolved... meaning, there are many reasons.
