INSTALLATION
1. See Figure 4-93. Check rubber seals on electrical and

2. Pump may be placed inside fuel tank by hand. Bending a
90 degree twist in the pump wiring will simplify locating
the fuel and electrical outlet holes. However, if problems
occur during installation:
a. Obtain a stiff piece of wire approximately 24 in.
(61 cm) long.
b. Attach pump electrical connector to wire.
c. Feed wire into tank through fuel filler cap hole and
out through electrical fitting hole (smaller hole) in
bottom of tank. Gently pull on wire to seat pump.
3. Install pump assembly inside tank through fuel filler cap
hole. Position pump assembly with filter facing motorcy-
cle license plate. When properly aligned, press both
