I need to put a fuel cell in my '71T with a 3.2.
The Porsche specific ones are very nice but spendy.
Can anyone share their install of a "generic" fuel cell?
Thanks

Todd,
Unfortunately, those 911-specific fuel cells are expensive but darned well worth every dime.
The generic cells position the fuel several inches higher in the chassis due to the required steel box and given the weight of gasoline (8 lbs/gallon), thats a very significant difference in front CG.
My VERY best advice is to save your money to do this very important task the right way as you'll never regret it.

I completely agree with the principle of what you have stated re weight distribution and placement of the fuel supply in a 911, Steve, but I would remind you that today's unleaded gasoline actually weighs approximately 6.25pounds per U.S. Gallon at a temperature of 70 degrees Farenheit, not 8 lbs. as stated above. Doesn't significantly change the point you've brought up, but it's an inaccurate detail we don't need to propagate.

I would agree, spend the money on a proper cell that won't require cutting your chassis and drilling unnecessary holes. I helped design the first ones for the 911 with Fuel Safe and they fit pretty well.

If you want to go racing and are put off because a correct fuel cell is Spendy? you should stop now. The fuel cell will be the least of your Spendy items if you want to be competitive in the land of Cubic Money Racing.

Mine was just like the one above, a "911 specific" cell....but totally in black.
Looked great in the car.
One thing to remember is that the bladders don't last very long.
In reality, 5 years is tops for a bladder in a fuel cell.
I almost got 10 years out of mine before it started leaking fuel everywhere (didn't know at the time about the life expectancy of bladders....oops).
The replacement cost for these "911 specific" cell bladders is very high....nearly the cost of a new cell.
Think I was quoted something near $2000.
So factor that into your decision.
The square one's sit higher, but the bladders are much cheaper.
The "911 specific" cells fit the car much better, but will always have a higher operating cost.
Hope this gives you some more info.
ps: I had a lightweight aluminum skidplate made to protect the bottom of my cell....especially the square leading edge the hangs down low.
