Additional Equipment
Although dependent on the cell most
bladders can be equipped with additional
options.  Senders and collectors, for
example, are our most common additions.  
Extra plates and fittings are also one of our
specialties and can be placed anywhere on
the cell.
We now offer repair and modification services on any fuel cell (excluding Jazz and other rubber-based bladders) with a
manufacturing date within the past 5 years.  We can add on additional features, like collectors and senders, and perform
repairs and resizing.  All repairs are guaranteed for the remaining life of the cell and all additional equipment is guaranteed
for 5 years from date of installation.  Replacement parts, including senders, plates, and fitting hardware, are also available
and refurbishing of existing plates can be done.  Turnaround time can range between a few hours to a couple of weeks
depending on the service, so please contact us with what service your fuel cell needs.
Certain costs, such as replacement foam and resizing, are dependent on the
cell.  Most services, like replacement parts and additional equipment, can be
found in our
Product Cost page.  Please contact us with questions about
other repair costs and services.
