Specific steps and precautions must be followed for the removal and installation of intake manifolds on various engine types. For 196, 231, 252, and 350 Buick Engines, disconnect the negative battery cable. Drain the radiator. Remove air cleaner. Disconnect the upper radiator hose and heater hose at manifold. Disconnect other linkages and brackets like accelerator linkage and bracket, cruise control chain (if applicable), fuel line, booster vacuum pipe etc.On 1976 models, remove choke pipe from choke housing; label wire, hoses and bracket as necessary; On six-cylinder models, distributor cap and wires may need to be removed to access a Torx® head bolt. Also remove throttle linkage springs as necessary …then remove manifold itself. This entails using a new gasket with sealer on the rubber gasket seals …ensure proper alignment…and tightening bolts in specified order for installation purposes. For 305 and 350 Chevrolet Engines: Drain cooling system. Take off air cleaner assembly. Rmove battery ground…Then Upper radiator hose and heater hose from manifold … Then disconnect all linkages such as hoses associated with carburetor/manifold assembly,…and then distributor after marking rotor position….remove any other brackets or springs……Before unbolting it and removing it from the vehicle or engine so you can comprehend this better.…To install it back use old gaskets in opposite order while ensuring proper torque sequence is followed by bolts of the manifold will secure it tightly enough in place again . For 350 And 403 Oldsmobile Gasoline Engines: take off carburetor air cleaner first then drain radiator right away to prevent overheating…. Remove connecting upper radiator hose/bypass hose/heater hose To do this you might want to consider removing throttle linkage,vacuum & gas lines that are connected to carburetor , generator related brackets ,as well as some air conditioning parts . Then disconnect temperature gauge wire; EGR solenoid assembly, Idle Load Compensator unit and similar components. Also remove the EGR valve before taking off the intake manifold itself. Finally, clean gaskets surfaces, apply sealer, place gaskets…and secure manifold bolts in a certain sequence. For 307 Oldsmobile Gasoline Engines: take off carburetor air cleaner first then drain radiator right away to prevent overheating…. Disconnect all hoses such as upper radiator hose/bypass hose/heater hose Then, you should disconnected other things like throttle linkage,vacuum lines and gas lines. Besides, brackets related to generator/air conditioning could have been removed if necessary. As for electrical leads , they are disconnected after which components like the EGR solenoid assembly and Idle Load Compensator (ILC) are taken out . Take off the EGR valve then unfasten and take out the intake manifold bolts . In conclusion, clean gasket surfaces well using a suitable sealer. After that install all these manifolds' gaskets again properly into position while tightening their bolts in specific order only. For 265 And 301 Pontiac Engines: It is not necessary to follow a specific torque sequence during this process. Remove EGA valves except in 301 Remove intake manifold bolts after removing distributor… Drain radiator/block and remove various hoses plus brackets etc…Then you can pull out the intake manifold fast enough after unbolting it from an engine block. After that lay down new gaskets accordingly on both its sides, followed by applying sealer on them and finally fix up such with their corresponding bolts tightly. For 263 And 350 Oldsmobile Diesel Engines: take out air cleaner as well as draining radiator immediately Do so by simply undoing some hoses , brackets or even components like fuel injection pump along with its lines, vacuum pump or oil pump drive assembly …Remove also any other hardware including intake manifold bolts which when undone will lead to it coming out of the engine. Apply sealer, place gaskets and secure the manifold bolts ensuring that as well as reinstalling all removed components in reverse order.

Fuel is supplied by a high-pressure electric pump located in the fuel tank, and its pressure is regulated by a fuel pressure regulator.
