the larger (3/8) line coming to the tbi is the supply the smaller (5/16) line is the return
tbi
Differences with the rear main bearing, and the intake manifold angles
Info can be found here http://www.allpar.com/fix/80s-codes.html26 Peak injector circuit voltage has not been reached (need to check computer signals, voltage reg, injectors) (SEE NOTE #4 BELOW)NOTE #4.During cranking, the computer will test the current through the injector to see whether there's too much resistance in the injector's path. If there is, code 26 is set.The problem may be cured with tuner cleaner on the connectors.For TBI engines, the injector's cold resistance should be between 0.9 and 1.2 ohms (specs vary with year). This is a peak-and-hold injector. With the engine idling the peak period should be about 1.2 milliseconds whereas the hold period will vary. If it's lower than this at idle, then the injector's shorted or there's a defect in the injector driver circuit. (Bohdan Bodnar)
A tan/white wire goes from the sending unit to the fuel gauge typically on a (example) 1985 Chevrolet Silverado 305 tbi.
back by the distributor there is the fuel lines side by side... you will see the line with the pressure valve screw on cap... that is the feed line
depends if its fuel injected or carburated. tbi under drivers side door, carb urated should be right by carb
The fuel pump relay on 1986 Chevy Elcamino 4.3 TBI is in the Fuel Injection Tank.
Usually located on frame rail driver's side, follow fuel lines if its FI or TBI its always in the gas tank.
tbi is Chevy's abbreviation for Throttle Body Injection. In this type of fuel injection system fuel is squirted into the throttle body above the manifold.
The fuel pressure regulator in that 96 GMC 4.3 TBI is located in the throttle body.
THEY ARE THE FAN AND FUEL PUMP RELAYS,,,
AnswerIn the fuel tank Actually the fuel pump is only in the tank on the tbi models, if it is carborated then it is on the front of the engine on the bottom right side(facing the block)
fuse link wire on 1983 crown Victoria that goes to fuel pump was getting hot with ignition switch off?
If it is a -TBI- then the pump is mounted in the gas tank, but if it has a -4bbl- then it should be mounted on the engine block passenger side.
your fuel injectors are mounted on each side of the intake manifold....if V-6,youll have 3 on each side, if V-8, youll have 4 on each side. Unless it is "TBI" Throttle Body Injected...then the above does not apply.
