Ford Bronco/F-Series Fuel & Exhaust Systems - Haynes Ch. 4 Specs & Torque

This is the opening page of Chapter 4, 'Fuel and exhaust systems,' from a Haynes-style repair manual covering Ford Bronco and F-series trucks (it references Bronco and F350 cab chassis, and directs readers to Chapter 13 for 1984 and later models). The page includes the chapter contents listing 13 sections covering the carburetor (external adjustments, removal/installation, servicing and overhaul), automatic choke, exhaust system, fuel filter, fuel lines and valves, fuel pump, and fuel tank procedures. The Specifications section states the fuel pump is mechanical and camshaft-driven, with pressure of 6.0-8.0 psi (all except in-line six-cylinder) or 5.0-7.0 psi (in-line six), and a volume of 1 pint in 20 seconds at idle rpm. Torque specifications are given for the exhaust system: inlet pipe-to-exhaust manifold 25-38 ft-lb, MTA U-bolt 5-8, catalytic converter U-bolts 35-45, brackets 17-24, plus general bolt/nut torques by diameter (5/16 in: 12-17 up to 1/2 in: 75-105 ft-lb). The General Information section describes the fuel system layout, including auxiliary tanks with a fuel flow control valve, and notes the carburetor's interrelation with emissions controls (Chapter 6). Section 2, carburetor servicing and overhaul, begins at the bottom of the page.
