INTRODUCTION

The 5.4L engine is available with two bi-fuel options, Liquid Propane Gas (LPG) or Compressed Natural Gas
(CNG). The fuel control system on these engines is separate from the gasoline fuel system and has unique parts.
This article only covers removal and installation procedures for alternate fuel components on bi-fuel
gasoline/LPG vehicles. For removal and installation procedures for alternate fuel components on bi-fuel
gasoline/CNG vehicles, see REMOVAL & INSTALLATION - F150 PICKUP - BI-FUEL -
GASOLINE/CNG article. Procedures for systems and components that are the same as gasoline powered
models are not included in this article. See REMOVAL & INSTALLATION - BLACKWOOD,
EXPEDITION, F150 PICKUP & NAVIGATOR - GASOLINE article. Alternate fuel powered vehicles
utilize special fuel filler valve, fuel tanks, fuel pressure regulator, fuel lines, fuel rails and fuel injectors. See
Fig. 1 .
