with the tie wraps provided. Make sure the
hose end is securely clamped onto the regu-
lator outlet using one of the supplied #4

diagram. Connect the FMU outlet hose
(attaches to the center fitting on the bottom of

ed. Secure the fuel lines away from abrasion
and exhaust with the tie wraps provided.

um hose to the fitting on top of the FMU.
