PULSE Installation, Commissioning and Servicing Manual - Revision 19
5.1 Shortening Hoses
Minor hose elongation will occur on all hoses. Gallagher supply hoses at a standard
length that maintains clearance from touching the ground, even after elongation. In some
instances however, certain fuel compositions will result in hose elongation that brings the
hose close to, or even touching the ground.
A hose that touches the ground is shortened by an amount equal to twice the required
ground clearance. Use the clearance provided by the other grades to maintain a consistent
appearance across all hoses.
i.
Secure the hose end (with the fitting still
attached) into a vice.
ii. Loosen the hose end fitting by inserting
the “T tool” and turning it anti-clockwise.
iii. Remove the hose end fitting from the
hose.
iv. Cut required length from the hose end
using the straight cut knife.
Re-Attaching the Hose Fitting
a Ensure the hose end
is 100% clean, dip in
water and shake off
any excess water.
b Push the hose end
fitting onto the hose
so that the hose is
seated properly and
visible through the
inspection hole.
c Grease the thread of the
nozzle end fitting, insert
it and tighten fully using
the “T tool”.
