(9) Working through access opening at wing station 129.3 (lower wing surface), disconnect
electrical wire from fuel sender unit terminal. Remove the five bolts securing fuel sender unit
and remove sender unit from fuel cell.
(10) Inserting arm between fuel cell and top of wing, separate velcro strips which hold fuel cell in
place.
(11) Fold fuel cell into a manageable form and withdraw it through the access opening at top of
wing.
B. Cleaning
(1) New fuel cells kept in their shipping containers should not require cleaning prior to installation.
If a cell should become dirty, clean with soap and warm water.
(2) Prior to removal, a used cell should be drained, purged with fresh air and swabbed out to
remove all traces of fuel. Upon removal the cell should be cleaned thoroughly with soap and
warm water.
C. Inspection
(1) Inspect fuel cells during regularly scheduled airplane maintenance inspections.
(2) Inspect interior of each cell for cracking, porosity or other signs of deterioration.
(3) Inspect nipple as follows:
(a) Attempt to scrape the rubber off the nipple fitting with a fingernail. If rubber has not
degraded, the fingernail will glide across rubber without damage to the rubber. If an
unsatisfactory condition exists, the fingernail will dig into the rubber.
(b) Deteriorated rubber has consistency of either art gum or chewing gum. Usually it will have
changed from a light tan color to a dark reddish-brown, bluish or greenish color,
depending upon the color of fuel used.
(4) Replace any cell found seeping or with soft nipples.

(a) all sharp edges have been rounded off. Where this is not possible tape over all sharp
edges or rough rivets;

compartment.
