Six Cylinder Fuel Pumps:
AC Fuel Pump With Air Pump:
This Fuel Pump came as standard equipment on grey Holden Engines from 48-215(FX) through to FB.
From EK on the cars had electric wipers.
AC Fuel Pump:This Fuel Pump came as standard equipment on grey and red Six Cylinder Holden Engines from EK - VB.
AC Fuel Pump Diaphragm Replacement:
Carter Fuel Pump:This Fuel Pump came as standard equipment on Carburettor Blue and Black Six Cylinder Engines.
It can be fitted as a replacement for the AC Glass Bowl Fuel Pump found on Red abd Grey Engines.
Carter Fuel Pump Components:
Carter Fuel Pump Operation:
As long as the Floatbowl is full, the diaghram will stay in the downmost position holding pressure in the fuel line.
Pump Pressure and Gasket Thickness:Changing the thickness of the gasket between the pump and the block can affect the fuel pump.
A thick gasket will lower the fuel pressure by reducing the pump's stroke. A thin gasket will raise the fuel pressure by increasing the pump's stroke.
Fuel Filters:Re: The use of metal fuel filters between the pump and carby.

yea they do i have a Z200 in the engine bay of my T P I chev350 bit of heat in there so i put one in just in case. i was told the Z200 ryco will also pick up bits of metal as it is magnetic

An Inline Fuel Filter fitted to the Tank side of the Pump will save you headaches if any contaminant gets pulled through from the tank. A U-Shaped Loop will trap Water (the heavier of the 2 liquids) in the lowest point and allow the Fuel to float past on top. At the next tuneup, release the liquid in the loop and inspect for any Water.
Changing Out the Pump:Some tips. 1. Put a smear of Oil on the input pipe so that the Rubber Fuel Hose can slide on easily. Without the Oil the Hose can bind. 2. Use Thread Tape on any difficult Fuel pipe Threads to keep them from leaking. 3. Put Thread Tape on the Fuel Pump Mounting Bolts to prevent Oil from walking up the Threads. Remember that the Mounting Bolt Holes are open and face the Camshaft. When the Camshaft gets spinning it flings hot Oil at the Bolts and the hot Oil tries to walk up the Threads and drip onto the Ground. Commodores were sold with Bolts that had blue Sealant already present on them to prevent the leak. 4. After swapping out the Pump and doing the first startup, try to leave the Engine idling for 5 mins so that the empty Pump, Intake Lineand Supply Line can fill up. If you shut the Engine down too soon the carburettor will not have enough fuel to fill up properly and the next start may require Carburettor Priming. If Fuel leaks appear the Engine will have to be shutdown immediately of course.
under the glass.The Toricellian Vacuum is the vacuum that appears in the top of liquid thermometers and the same effect is what you're seeing in the filter. Consider the Fuel Supply Line to be the Thermometer with the Fuel Tank at the bottom and the Fuel Pump at the top. The vacuum appears at the top near the Fuel Pump.When you shut the engine off, a large vacuum appears as the fuel tries to run back into the tank. Old kerosene heaters used vacuum in the same way. The vacuum inside the glass supply bottle prevented kerosene from flowing out until the neck became uncovered. Once the neck became uncovered kerosene flowed into the heater until the air supply to the bottle was strangled by the same kerosene.The vacuum at the high point of the bottle stopped the kerosene from flowing out.T
