Priming pump bulb pumps gas/oil mixture out on the ground. Where does the lower end of the tubing attach to? Do not have a manual There is a cap on top of the fuel container with one line attached and an opening with no tip to attach the loose end of the primer tubing coming off of the carbuerator

The fuel pump uses impulse air from the crankcase.

To check impulse air, leave the oil dip stick cap loose and resting freely on the fill tube. If cranking the engine causes the dipstick to move up/down then likely there's sufficient impulse air.

For the pump to operate, the tube from the pump to the crankcase cannot be cracked and must be secure at both ends. The oil fill cap must be in place with no gross leaks.

See attached pic for proper pump connections. Some pumps are different and can be confusing. The connection that is in a different plane (pump body) will be impulse input.

Hi there:

1. Drain the cooling system.

CAUTIONWhen draining the coolant, keep in mind that cats and dogs are attracted by ethylene glycol antifreeze and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.

1. Remove the bolts attaching the fan shroud to the radiator and position the shroud over the fan.
2. Remove the upper intake manifold and throttle body (see Fuel System ).
3. Remove the nuts and lockwashers attaching the engine support insulators to the chassis bracket.
4. If equipped with an automatic transmission, disconnect the oil cooler line at the left side of the radiator.
5. Remove the exhaust system.
6. Raise the engine and place wood blocks under the engine supports.
7. Drain the crankcase.

CAUTIONThe EPA warns that prolonged contact with used engine oil may cause a number of skin disorders, including cancer! You should make every effort to minimize your exposure to used engine oil. Protective gloves should be worn when changing the oil. Wash your hands and any other exposed skin areas as soon as possible after exposure to used engine oil. Soap and water, or waterless hand cleaner should be used.

Remove oil pan, making sure to drain oil first. Remove oil pump attaching bolts. Lift off oil pump and withdraw oil pump drive shaft.
INSTALLATION;
Prime the new oil pump by filling either the inlet or outlet port with engine oil. Rotate the pump shaft to distribute oil within the pump body. Insert oil pump drive shaft into block dwith the pointed end facing inward. The pointed end is closest to the pressed-on flange. Place oil pump into position with a new gasket and install attaching screws. Tighten the screws to 15-22 foot pounds of tourque. Clean and install the oil pump inlet tube and screen assembly with a new gasket. Tighten the bolts, then replace the oil pan.
Oil Pan;
Clean of any debris and replace gasket. Fit the oil pan bolts and tighten in two steps. Start from the rear/left hand side and tighten first, then tighten the bolt in the front/right side. Alternate from rear to front, working from back to front and front to back.

This is straight from the book.

2. Position the intermediate driveshaft into the distributor socket. With the shaft firmly seated in the socket, the stop on the shaft should contact the roof of the crankcase. Remove the shaft and position the stop as necessary.
   
4. Insert the intermediate driveshaft into the oil pump. Using a new gasket, install the pump and shaft as an assembly. Do not attempt to force the pump into position if it will not seat readily. If necessary, rotate the intermediate driveshaft hex into a new position so that it will mesh with the distributor shaft.
   
5. Torque the oil pump attaching bolts to 10–15 ft. lbs. on the 6-cylinder engines, and 22–32 ft. lbs. on the 302 V8.
   
6. Clean and install the inlet tube and screen assembly.
   
7. Install the oil pan
   

Remove the fuel fil hose,and vent hose,and remove fuel tank straps,with jack supporting tank,lower enough to remove wire connector,and fuel lines .Remove tank from under vehicle,and remove the ring retainer,and pull the fuel pump assem,from tank.Follow instructions in the box with the new fuel pump.

To me it sounds like your line is clogged. It pumps towards the tank but not towards the carb. Open it up, and check your lines out, if it's clogged it could be a little too much oil (just saying if it smokes alot when it's on).
