QuoteFuel safe has you send in your old fuel cell to them to guarantee a fit I assume. Given that they require to have your old fuel cell anyway I doubt any additional paperwork from Shelby would be helpful or what am I missing?
Bob, I do not believe you are missing anything. I was under the impression that the OP did not know the bladder manufacturer nor any of the specifications of the bladder which is why I suggested he have SAI look up those details for him.
Did not know that fuel safe requires they do the bladder installation, shipping the fuel cell to and from isn't the cheapest thing but I suppose it falls under a maintenance expense for the owner.
