4.14FUEL PUMP
GENERAL
When servicing the fuel system, do not smoke or allow
open flame or sparks in the vicinity. Gasoline is extremely
flammable and highly explosive, which could result in
death or serious injury. (00330a)
Carefully inspect hose for cuts, tears, holes or other damage.
Replace hose if any damage is found. Even a small hole can
cause a reduction in fuel pressure.
Refer to the electrical diagnostic manual for information on the
function and testing of the fuel pump.
REMOVAL
To prevent spray of fuel, purge system of high-pressure
fuel before supply line is disconnected. Gasoline is
extremely flammable and highly explosive, which could
result in death or serious injury. (00275a)

8.17 INSTRUMENTS: FXDWG/FXDC/FXDF.
b. For FXDL, FXDB models, see 8.18 INSTRUMENTS:
FXDL/FXDB.
c. For FXD models, see 8.15 FUEL GAUGE.
4. Disconnect console wiring.
Gasoline can drain from the crossover line when discon-
nected from fuel tank. Gasoline is extremely flammable
and highly explosive, which could result in death or ser-
ious injury.Wipe up spilled fuel immediately and dispose
of rags in a suitable manner. (00259a)
5. Drain fuel tank.
a. Obtain a short section of hose (5/16 inch I.D.). Insert
bolt in one end of hose and install hose clamp to
ensure that end is securely plugged.
b. See Figure 4-34. Cut clamp (1) from one end of
crossover hose (2). Quickly replace crossover hose
on fuel tank fitting with open end of short hose while

(1) [141].
7. Remove vent hose (3).
8. Remove top plate screws (2) and discard.
9. See Figure 4-36. On FXDL, FXDB, FXDWG, FXDF and
FXDC models, rotate top plate (3) until vent tube (1) clears
fuel tank.
