Section 86 (Engine Removal, Overhaul & Installation - F150 Pickup - Bi-Fuel): 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, overhaul and installation procedures for alternate fuel components on bi-fuel vehicles. Procedures for systems and components that are the same as gasoline powered models are not included in this article. See REMOVAL, OVERHAUL & INSTALLATION - BLACKWOOD, EXPEDITION, F150 PICKUP & NAVIGATOR - GASOLINE article. Alternate fuel powered vehicles utilize special fuel filler valve, fuel tanks, fuel pressure regulator, coalescent filter assembly, fuel lines, fuel rails and fuel injectors. See Fig 1-Fig 3 .
