Installation is easy and one person can
install the bladders in 2 1/2 - 3 days or less. Two people will take about 2 days.
remove the existing metal tanks and install the new fuel bladders in the same
fuel cavity. Taping the fuel cavity with PVC tape (supplied with the bladders
by our FAA Approved manufacturer), which prevents chafing is really the slowest
part of the entire installation. Install the supplied check valve in
the vent line and the installation is complete. We use the original Yak 52
metal tank fuel senders which you "calibrate" to the stock fuel
instrument the first time you fill the bladders.
It is highly recommended you seriously consider
installing a fuel flow instrument, such as the JPI FS450G (be sure it is the G
model) which will accurately measure not only the fuel flow, but the total fuel
remaining in the fuel tanks. Tweaking or calibrating what is called the K
factor for the fuel flow transducer is done each time you fill up for the first
few fill-ups. Once this is done, the fuel flow instruments accuracy
calculating the fuel remaining in the tanks is incredible.
The price of the bladder set, including full
foam, fuel filler plate (we use the original Yak fuel caps now) and check valve
is $5200 US plus freight. Delivery is approximately 8 weeks from receipt of order. Please don't

questions which you may have or for additional information.
