Hi folks, I have a 2003 Van Diemen RFS03 sports racer that I need to replace the fuel cell bladder. The bladder resides in the cockpit all along the entire rear bulk head. It is covered by a sheet of fabricated aluminum that also serves as the seat back rest. I have removed the “inspection” plate and have tried to remove the bladder through that opening and I simply can’t compress the bladder enough to pull it through the hole because of a series of baffles built into the bladder. I believe the proper removal and instillation process is to remove the aluminum cover that covers the entire bladder. This would involve drilling out the rivets and releasing the sheet from its epoxy bond, replacing the bladder and re-epoxying and riveting the sheet back in place. Because the sheet is so thin (.050) I don’t believe it is a critical part of the tubs integrity, thus removing and replacing it would have no consequences. But to be on the safe side I thought I’d throw this out to you folks to see if anybody had some wisdom on tricky bladder replacements. I have searched the forums and have not been able to find anything on bladders. Thanks in advance for your time.
