The base Circle is the radius of the circle of the pumping cam that does not lift the pump lever causing it to pump or stroke.

I change my fuel pump , filter on my 1994 Isuzu pickup truck ,4cylinder 2.3 liters and I have no gas a carburetor. I try using starting fuel to start it and its starts and dies . How can I fix it?


Take the gas line off at carb, and crank the engine over. If gas does not start spurting out from the gas line, then the new pump is not working right. Maybe the pump arm is not situated right against the eccentric gear that makes the pump work. You would need to re-situate the fuel pump.

I HAVE A 65 MUSTANG WITH AN ELECTRIC FUEL PUMP AND I DO NOT LIKE IT BECAUSE IS TO NOISY, CAN I REPLACE IT WITH A MECHANICAL ONE?


YES if you have an early front cover on timing chain, and eccentric cam . The fuel pump on early cars ran off the cam shaft. IF this is a late model engine and fuel injection... the answer would be no.

How do you install a fuel pump on to a 1966 mustang with a straight 6?


Apply sealer to both sides of the gasket and position it on the pump. Hold the pump in position on the mounting surface and make sure the rocker arm is hitting the cam eccentric. Hold the pump tight against the block and install the bolts. Tighten them alternately, hook up the fuel lines and start the engine to check for leaks. Hope this helps.

I need to replace the fuel pump in my 1985 Chevy S10 pickup, need all help. What is the procedures?


EXACT PROCEDURE ! Please Rate Me Fairly for this!! Thank you And Good Luck !!


ELECTRIC PUMP

REMOVAL
  1. Before servicing the fuel pump the fuel system pressure must be relieved. See: Fuel Pressure Release
  2. Disconnect the negative battery cable.
  3. Raise the car on a hoist.
  4. Remove the fuel tank. See Fuel Tank / Service and Repair.
  5. Remove the fuel tank sending unit and pump assembly by turning the cam lock ring counterclockwise. Lift assembly from the fuel tank.
  6. Pull the fuel pump up into the attaching hose while pulling outward away from the bottom support. Take care to prevent damage to the rubber insulator and strainer during removal. After the pump assembly is clear of the bottom support, pull the pump assembly out of the rubber connector for removal. NOTE: Inspect the fuel pump attaching hose for any signs of deterioration. Also check the rubber sound insulator at the bottom of the pump. Replace damaged or deteriorated parts.
INSTALLATION
  1. Push the fuel pump assembly into the attaching hose.
  2. Position the fuel tank sending unit and pump assembly into the fuel tank. Use a new "O" ring seal. NOTE: Care should be taken not to fold over or twist the strainer when installing the sending unit as this will restrict the flow of fuel. Also, verify that the strainer does not block the full travel of the float arm.
  3. Install cam lock over the assembly and lock by turning clockwise.
  4. Reinstall fuel tank.
MECHANICAL PUMP

REMOVAL and INSTALLATION

NOTE: To ease pump installation, rotate the camshaft so the camshaft eccentric is out of the way of the fuel pump rocker arm.

  1. Disconnect fuel lines from fuel pump.
  2. Remove fuel pump mounting bolts and the fuel pump.
  3. Remove all gasket material from the pump and block gasket surfaces. Apply sealer to both sides of new gasket.
  4. Position gasket on pump flange and hold pump in position against its mounting surface. Make sure rocker arm is riding on camshaft eccentric.
  5. Press pump tight against its mounting. Install retaining screws and tighten them alternately.
  6. Connect fuel lines. Then operate engine and check for leaks.

How to change fuel pump ?


  1. Disconnect the negative battery cable.
  2. Disconnect fuel tank hose at the fuel pump, and plug the hose with a bolt or wooden dowel to keep any fuel from flowing out wires. Check the hose and if it is frayed or cracked, replace it with new fuel line hose.
  3. Disconnect the outlet line to the carburetor. Use a wrench on the fuel pump fitting and another on the line nut.
  4. Remove the two attaching bolts and remove the old fuel pump. Clean off any old gasket material from the mounting surface of the engine.
Installation:
  1. Apply a coat of gasket sealer on both sides of the new gasket. Put the attaching bolts through the new pump and slip the gasket over the bolts.
  2. Install the new pump on the engine. Make sure that the rocker arm in the pump is against the eccentric inside the engine, or that the push rod is correctly installed in both the engine and the fuel pump. If the push rod slides out, you can pack it with some heavy grease to hold it in place while you install the pump.
  3. Attach the fuel outlet line that runs to the carburetor. If it's difficult to connect, remove the other end of the line from the carburetor. Connect the line to the fuel pump, and then reattach the other end to the carburetor. Use a wrench to hold the fuel pump fitting and tighten the line nut with another wrench.
  4. Attach the fuel inlet hose from the gas tank, and the vapor return hose (if the vehicle is equipped with one). Tighten all clamps.
  5. Reconnect the battery ground cable, start the vehicle and check for leaks.
Hope that works
